Usability  
Improving the usability of Unigraphics NX continues to be our focus as it has been for a number of releases. This release continues to emphasize making Unigraphics NX easier to learn for new users, easier to understand and more consistent.  
This release particularly focuses on Drafting, Modeling and Shape Studio improvements. Drafting has dramatically streamlined creating and editing of dimensions and notes, utilizing a dialog-less interaction that directs the users focus directly to an always up-to-date preview in the graphics window. Annotation settings can quickly and easily be changed by using on-screen icon boxes or MB3 menu options during preview. Views are now selectable objects and can easily be edited by using a view-specific MB3 popup menu.  
Modeling has a brand new Part Navigator that represents a different way of looking at the data in your part file. Use the new Part Navigator to organize, select and control the visibility of your data as well as simply browse to understand it. Drafting information is now included as well. Selection Intent has been added to most Modeling features that select multiple curves, edges and faces. This lets you define your intent at a high level - selection is more efficient and you also increase the robustness of updates during edits. Many Modeling functions have a new streamlined user interface; for example, Extrude, Dynamic Law Extension, Four Point Surface, and Sketcher.  
Shape Studio offers a dramatically improved X-Form and Match Edge functions to adjust curves and surfaces. New visualization techniques such as Mirror Display, Non-Proportional Zoom and Highlight Line Analysis assist you in analyzing your model quality. You will find more details on all of these improvements throughout this What抯 New Guide, denoted by the icon shown below.  
Finding Usability Enhancements  
Usability enhancements are spread across the various product lines in this release. Each Usability enhancement is documented in this What's New Guide in the topic for that particular product. For example, you'd find CAM Usability enhancements in the Manufacturing topic. Usability enhancements are denoted by the following icon to the left of the enhancement name, for example:  
Palette Support  
Palette Enhancements  
What is it?  
In the first release of Unigraphics NX, we introduced the ability to use palettes to drop objects into a Unigraphics session. In this release, we've extended this functionality by allowing you to:  
add objects from a Unigraphics NX session to a palette using drag and drop or cut and paste menu commands  
display a specific menu by right-clicking in a palette or on a palette entry. Menu options depend upon the palette or entry type.  
customize palettes with a new Palette Customization dialog  
modify palette properties with a new Palette Properties dialog  
edit a palette entry with a new Edit Entry dialog  
view palette entries using additional view types: Previews, List View, Icons, Tiles, or Thumbnails  
insert a specific palette or template type: Open, Bookmark, Inferred, Component, Master Model template, Master Studio template, Non-master Drawing template, (generic) template, or Visualization Template  
use an open, XML-based and internet-ready format for third parties and other high level applications  
Why should I use it?  
Use it to easily add, view, and edit palette objects.  
Where do I find it?  
You can find these new features on the Resource Bar.  
Visualization Settings Templates  
What is it?  
A visualization settings template is an easy way to capture Unigraphics NX visualization settings and propagate the captured settings into other parts. For example, you might have an existing part that has visualization settings that are 90% of what you want for a new part. You can now easily propagate those settings into a new part or modify settings in an existing part.  
This feature allows you to:  
Extract visualization settings from existing parts  
View visualization settings so you can verify them or perform modifications  
Save visualization settings in a template file  
Drag and drop a visualization settings template file onto a new or existing part  
Choose from a variety of standard template files, as an alternative to creating custom template files  
Why should I use it?  
You might use visualization settings templates:  
as a starting point for standard industrial design  
to maintain company standards  
to retain settings for demonstrations  
Where do I find it?  
From within any standard palette window, click on MB3 and select Insert->Visualization Template.  
This option is not available in "non-standard" palette windows, such as the History palette. Therefore, to create a visualization template, you must open a standard palette window or create one and then perform the MB3->Insert->Visualization Template operation. To open an existing palette, click on a palette tab on the Resource Bar. To create a standard window palette window, from the History palette, click MB3 and select "New" or select Preferences->User Interface and create one using the options on the Resource Bar page.  
Studio Showroom Environment  
What is it?  
In this release, enhancements have been made that improve the usability of the Studio Showroom environment. You use the Studio Showroom Environment to set up an environment that allows you to see how your model will look in various settings and at different angles. Enhancements include:  
Supports the environment cube in Studio Display mode. It was previously only supported in High Quality Shading.  
Provides dynamic cube editing. You can dynamically edit cube size, location, and orientation. It also allows you to try out different environment images and see the reflection of the environment on the model. Furthermore, it allows you to easily view and navigate the model within the environment.  
Provides default environments. Unigraphics NX provides several default environments (showroom, outdoor scene, etc.). This allows you to select a predefined environment. The default environments are easily accessible from the Default Environment palette in the Resource Bar.  
Allows you to assemble user-defined environments. Showrooms provides an easy user interface allowing you to create and edit your own environment. You can assign a different TIFF file to each wall and dynamically view the result, such as the reflection of each wall on the model. The system stores the environment files that you create in a directory specified by the UGII_USER_SHOWROOM_DATA_DIR environment variable. We recommend that you define this environment variable and use its associated directory as a central storage for all User Showroom Environment files. The directory must have full write permission. Unigraphics NX searches in this directory to resolve all part references to environment files. If not defined, the system uses the UGII_TMP_DIR/user_showroom_data_dir directory to store all user showroom environment files.  
Turntable feature. Provides an easy interface to create turntable viewing within the environment cube. Provides two turntable modes: Part Rotate and Walk Around. Part Rotate allows you to define the speed and axis of rotation. In this mode, the background remains fixed. You can view the reflection of environment on all parts of the model as it rotates. Using Walk Around, you can set the "eye point." In this mode, the model remains fixed; the background changes as the "eye" moves around the model. Same as the current animation turntable.  
You can easily turn the display of the environment cube on and off by clicking the Show Environment Cube icon on the Visualize Shape Toolbar.  
Why should I use it?  
Use it when designing home, office, or any industrial product that requires aesthetic engineering.  
Where do I find it?  
To open the Environment dialog, click on the new Studio Showroom Environment toolbar icon on the Visualize Shape toolbar or select View->Visualization->Showroom Environment.  
Materials and Textures UI Enhancement  
What is it?  
The user interface for High End Visualization has been partially redesigned for improved ease of use. We have enhanced our Materials UI by moving much of it to the Unigraphics NX Resource Bar and providing immediate access to a wider range of materials. The Resource Bar now provides access to:  
a pre-defined palette of materials  
a user's working palette of materials  
Lightworks and third-party supplier archive libraries of materials  
This redesign also incorporates new functionality, providing access to more materials and improved access and control over archive libraries. The additional functionality:  
improves the material editor  
generates thumbnails for all material entries on palettes  
improves material previewing  
provides drag and drop support from palettes to the model  
Also, to follow suit with Lightworks direction of providing a material with texture attributes, we have combined Materials and Textures. This simplifies the user interface, and, as suggested, aligns us with all archive library entries provided by Lightworks and their affiliated third-party library suppliers.  
Why should I use it?  
These improvements make it easier to create more realistic models, both in Studio Display Mode and in Photo-Realistic Rendering. You have access to a wider range of materials. You can also edit archive material attributes, view better previews of materials, and place materials on surfaces more easily than before, both from within the materials context or while in global selection.  
Where do I find it?  
Selecting the Materials toolbar item or selecting View->Visualization->Materials displays the palette items for the pre-defined palette and your working palette, as well as the navigator for the Lightworks Archive Libraries.  
Snap View  
What is it?  
Snap View orients the current view to any of the standard orthographic views. The Home and End keys orient the current view to TFR-TRI and TFR-ISO.  
Press the Snap View function key, F8, to orient the current view to the closest orthographic view. Press Home to align the current view to TFR-TRI. Press End to align the current view to TFR-ISO.  
Why should I use it?  
To orient the view to any of the standard view orientations. This allows you to manipulate views quickly.  
Where do I find it?  
The F8, Home, and End keys.  
Snap Point  
What is it?  
The Snap Point tool, which provides inferencing and graphical feedback while you specify a point, is now available in more places throughout Unigraphics NX. In many functions, you will now see Snap Point graphical feedback and point inferencing as you specify points. You can turn specific inferencing options on and off in the Snap Point toolbar or display the full Point dialog from the toolbar. In the Point dialog, the inferred mode also provides Snap Point feedback and inferencing. To specify a point without inferencing, switch to one of the more specific modes in the dialog. The Snap Point toolbar will not appear in this case.  
Why should I use it?  
Use this tool to quickly indicate a point.  
Where do I find it?  
Most functions which previously displayed a Point menu now use Snap Point. You will know Snap Point is active when graphical feedback and snapping occur during Point specification. When Snap Point is active, the Snap Point toolbar should display automatically. If it is not displayed, open the MB3 popup menu in the toolbar area or select Tools->Customize and choose Snap Point on the Toolbars page.  
Geometry Tools Enhancements  
What is it?  
There are several enhancements to geometry tools in this release. The enhancements:  
provide new options for -XC, -YC, and -ZC on the Vector Constructor dialog and the embedded Vector Tool menu.  
provide one step to set the WCS to the Absolute CSYS, one step to set the View to the WCS, and one step to specify X, Y, and Z constants in the Plane dialog. Use it when you are specifying a vector, CSYS, or plane.  
Why should I use it?  
It provides quicker access to functionality.  
Where do I find it?  
You can find it anywhere you specify a vector, CSYS, or plane.  
Cut, Copy, and Paste Enhancements  
What is it?  
This feature extends cut, copy, and paste operations to almost any object. Instead of using an import/export operation, you can now accomplish the same task with a few keystrokes. In general, geometry re-use is much easier and faster.  
Select the geometry you want, then click Cut (Ctrl+X) or Copy (Ctrl+C). Move to a different part, location, or drawing, and click Paste (Ctrl+V).  
The system performs paste operations relative to the WCS. To transform geometry, cut or copy, double-click the WCS and reposition it, and then paste.  
To paste to a different or absolute coordinate system or to a different layer, use Paste Special.  
Why should I use it?  
Use it to make you more productive.  
Where do I find it?  
You can find it on the Edit menu or through the standard cut, copy, and paste shortcuts.  
Part Attributes  
What is it?  
You can now create, edit, and view part attributes using a part's Properties pop-up menu on Windows Explorer. You can also cut and copy part attributes from Windows Explorer and paste them to:  
the Attributes page in an active Unigraphics NX session (File-&gtroperties->Attributes)  
another Unigraphics NX part  
a text editor  
This feature does not require an active Unigraphics NX session and works only for parts created in Unigraphics NX2 and later.  
You cannot view or edit the cached part attributes that are saved for the component in higher-level assembly parts with this method.  
Why should I use it?  
Use it to create, view, modify, and delete part attributes without fully loading the part.  
Where do I find it?  
Click MB3 on a Unigraphics NX .prt file in Windows Explorer.  
Directory Selection Tool  
What is it?  
The Directory Selection tool allows you to browse and select a directory.  
Why should I use it?  
Use it because it’s easier to find and correctly specify a directory by browsing to it rather than typing in the path to the directory in an entry field.  
Where do I find it?  
Select the Browse button in the following dialogs, directories, and reports:  
Load Options dialog  
(File->Options->Load Options, select the Define Search Directories… button)

Delete Key Accelerator  
What is it?  
While in Global Selection, the delete key now deletes all selected objects.  
<Ctrl>+<D>, which is synonymous with the Edit->Delete menu option, is still available at all times.  
Why should I use it?  
Use it as a shortcut to delete objects.  
Where do I find it?  
It is available at all times in Global Selection.  
Export to Spreadsheet  
What is it?  
The new Export to Spreadsheet option lets you export the contents of a navigator or a tree-based dialog to the spreadsheet.  
The Export to Spreadsheet option is similar to the Export to Browser option, which exports dialog or navigator contents to your default browser.  
Why should I use it?  
The spreadsheet tools give you many options for analyzing and publishing the data. Among other actions, you can sort or modify the data, and change the cells' colors and text. See the Gateway Help for more information about the spreadsheet.  
Where do I find it?  
On the background menus of many navigators (such as the Assembly Navigator) and tree-based dialogs (such as the Mating Conditions dialog)  
MODELING  
Associative Offset Curve in Face Enhancements  
What is it?  
Enhancements have been made to the Offset Curve in Face function:  
Offset Curve in Face now creates an associative feature that appears in the Model Navigator.  
You can now select multiple sets of curves on multiple sets of faces.  
You can now use chordal and geodesic methods to offset a curve.  
Different spanning methods let you fill the gaps between the curves.  
The previous Offset Curve in Face menus have been replaced with icon options and a standard dialog.  
Offset Curve in Face now has options to trim or not-to-trim against the selected faces boundaries.  
Why should I use it?  
These enhancements can have many uses. For example, you could use offset curves as the path curves in the creation of associative flanges.  
Where do I find it?  
Modeling-> Insert-> Curve Operation-> Offset in Face  
Casting Design Tools  
What is it?  
Parting functions are required for patterns, core boxes and any tooling die work within the casting design process. The new Casting Design tools introduce functions that let you easily create the parting sheets. You can create the following types of parting sheets:  
Planar Parting Sheets - These are the most common type of parting sheet.  
Natural Parting Sheets - These are created by using a profile of parting lines, which you select. The following types of natural parting sheet are supported: Extrude Surface, Bounded Plane, Swept Surface, and Enlarge Surface.  
Stepped Parting Sheets - Creates a stepped parting sheet and joins it with a main parting sheet.  
There are also the following enhancements:  
Ramp Surface - Creates a planar transition between two different levels of parting sheets.  
Minimum Tool Land - Lets you specify a minimum tool land, a minimum dimension measured adjacent to a feature that necessitated the step, such as the width of a flat step parting.  
To operate:  
First, select the product body.  
Define the draw direction.  
Choose the type of parting sheet and follow the steps.  
Why should I use it?  
Certain manufacturing processes produce parting sheets as input for creating double-sided tapers on the product body. This new tool lets you easily create the parting sheets for the casting body.  
Where do I find it?  
Modeling-> Tools-> Casting Design  
Dynamic Extrude  
What is it?  
Dynamic Extrude improves how you create extrusions, and is more powerful and easier to use than the former method. Improvements include trimming options of Distance, Symmetric Distance, Until Selected, Until Next, Through All and new symmetrical offset and symmetrical taper options.  
Drag handles let you define limits, taper and offset values, and MB3 functions let you open options for taper, offset and trimming.  
Why should I use it?  
Dynamic extrude replaces the existing Extrude feature option. Use dynamic extrude to create new extruded bodies, and to subtract or add material to a body.  
Where do I find it?  
Creation: Modeling-> Insert-> Form Feature-> Extrude  
Edit an Extrude Feature: Edit or Edit Parameters from MB3 on the Extrude feature from either the graphics window or the Part Navigator
Dynamic Law Extension  
What is it?  
You can now create a law-controlled extension using on-screen dynamic handles. You can also use the standard procedures that were available in Unigraphics NX.  
To create a law extension dynamically:  
Choose a point along a curve.  
A WCS-like tool appears. Rotate the handles to specify the angle law and the length law. Alternatively, you can select the handle and enter a numeric value into the dynamic input box.  
Dragging an offset cone handle on the major direction changes the extension length from the point along the direction. You can also select the handle and enter a numeric value into the dynamic input box.  
Click MB3 or OK/Apply to create feature.  
Why should I use it?  
The Dynamic Law Extension lets you specify the angle or length law interactively while building a law extension surface. Dynamic feedback keeps you updated as you create the feature.  
Where do I find it?  
Insert-> Free Form Feature-> Law Extension or from the Free Form Feature toolbar.  
Enlarge Moved to Edit Menu  
What is it?  
The Enlarge function has been moved to Edit-> Free Form Features-> Enlarge (it was formerly found under Insert-> Free Form Feature-> Enlarge).  
Where do I find it?  
Edit-> Free Form Features-> Enlarge  
Extend and Trim  
What is it?  
The new free form feature Extend and Trim lets you trim or extend a set of faces (the target) by another set of faces (the tool).  
To operate:  
Specify the target by selecting a set of connected edges or faces.  
Optionally select the tool faces or edges or distance to limit the extensions.  
Why should I use it?  
Extend and Trim can be useful for the Body in White (BIW) process, removing unnecessary fillet types of surfaces from body panels in designing stamping dies, and in creating workarounds for feature modeling problems.  
Where do I find it?  
Modeling-> Insert-> Free Form Feature -> Extend and Trim  
Feature Data Access  
What is it?  
Feature Data Access lets you migrate an I-DEAS feature model into a Unigraphics NX feature model. The support of semantic data developed in I-DEAS is continued when you switch to Unigraphics NX.  
To operate:  
In Unigraphics NX, choose File-> Open.  
Go to your part file directory and choose the .xpk file type.  
Select the .xpk file your want to load.  
Use Model Navigator to review the model.  
Why should I use it?  
You would use this functionality whenever you decide to shift your feature-modeling platform from I-DEAS to Unigraphics NX.  
Where do I find it?  
File-> Open.  
Four Point Surface  
What is it?  
The new Four Point Surface tool lets you create a degree 1X1 surface by simply specifying four corners of a quadrangle on the screen or on the scan data.  
To operate simply specify four points on the screen. You can specify the four points using any of the following methods:  
Pick an existing point on the screen.  
Pick another arbitrary point on the screen.  
Define the coordinate location of the point in the input box.  
Pick a base point and create a point offset from the base point.  
Point specifying conditions:  
No three selected points can be collinear.  
No two selected points can be the same or at the very same location in space.  
Any four points specified by any or a combination of the above methods will always create a surface with degree 1X1, with the specified points as the corners of the surface.  
Why should I use it?  
You can use this new capability to create base surfaces that support the surface based (control point edit methodology) Class-A workflow. You can easily modify such a surface by increasing the degree and patch into a more complex surface with the desired shape.  
Where do I find it?  
Freeform Shape toolbar  
Insert-> Freeform Feature-> Four Point Surface  
Imageware Integration Enhancements  
What is it?  
Imageware Integration has been enhanced further.  
You can now perform digital inspection on Unigraphics NX data using the Imageware Inspection module. This lets you import "Scan Lines" into Unigraphics NX as degree 1 splines from Imageware, which helps you compare and modify the Unigraphics NX data to the evolving design.  
Why should I use it?  
Use this whenever you need to compare the geometric data with the physical data.  
Where do I find it?  
Tools-> Imageware Integration  
File-> Import-> Imageware
Model Compare  
What is it?  
The new Model Compare function lets you compare the geometries of bodies in two unrelated parts. It also lets you compare the features and expressions in two parts.  
To operate:  
Click the Body Compare or Part Compare option.  
Select the first body or part.  
Select the second body or part.  
Click Compare.  
Why should I use it?  
Use this function to compare two bodies or parts.  
Where do I find it?  
Model Compare is available in the Model Compare toolbar in the Modeling application.
Part Navigator  
What is it?  
The new Part Navigator represents a different way of looking at the data in your part file. Use the new Part Navigator to organize, select and control the visibility of your data as well as simply browse to understand it. In addition, Drafting as well as Modeling data is included in the Part Navigator.  
To open the Part Navigator, click its icon on the resource bar. As you construct your model or drawing, data is populated into the navigator window. You can double-click items for edit, select them for use in functions, and check and uncheck them to control their visibility or suppression status. Use MB3 to access a context specific popup menu on both the background area and on individual nodes.  
Why should I use it?  
The new form of the Part Navigator is based on reference sets, and within them the bodies that you have modeled, and below those bodies their features. This lets you find the relevant parts of your model extremely rapidly, and also lets you quickly make simple changes without having to first understand the model.  
Where do I find it?  
You can find the Part Navigator on the resource bar. Click or move the mouse over to the navigator region to make it appear. Double-click to pop the Part Navigator out of the resource bar for docking elsewhere.  
Part Navigator Dependency Panel  
What is it?  
The Dependency Panel is a special extension to the Part and Assembly Navigators that lets you quickly and efficiently check dependencies when editing your part or assembly model.  
To expand and use the panel in either of the navigators click on the arrow and then simply select the object of interest.  
You can explore items that use the selected object (children) or items on which they depend (parents).  
Use the Forward button to re-focus the display on the object of interest.  
Use the Details button if you抮e browsing features or components but want to understand the relationships at the edge, curve or assembly constraint level.  
Why should I use it?  
Use the Dependency Panel as a fast and easy way to understand dependencies and prevent problems, such as before proceeding with an edit. For example, before mating a new component you might want to understand how an assembly is currently constructed. Or, you may need to change a sketch, but must first check to see how many features reference it.  
Where do I find it?  
You can open the Dependency Panel from the bottom of the Part or Assembly Navigators. If your navigator display is of an appropriate shape, the panels may appear at the side with a separator bar between them and the main navigator; click on this to expand the panel area or collapse it.  
Part Navigator Dynamic Filtering  
What is it?  
The new Part Navigator includes filter masks that can be applied temporarily or permanently for normal display.  
You can filter the display both statically to remove data that is never of interest, and dynamically to allow you to find items or concentrate on particular areas of interest.  
Use the new filters to add or subtract items from the navigator and add them to a 搒um?that accumulates with what is displayed. You can add a filter quickly and then remove it. Or, you can edit more complex filters from the background popup filtering dialog. Available options include those to simplify the entire tree structure by removing construction information, removing all types or categories of feature, focusing on particular timestamps, and more.  
Why should I use it?  
Use the Part Navigator to filter views of the Model and Drawing data in your part.  
Where do I find it?  
You can invoke the filtering from the background popup, which also allows you to remove the last filter you applied, making it easy to quickly filter and restore the display. To open the filtering menu click MB3 on the title bar at the top of the navigator, the white space below the data it shows, or to the left of the tree in empty space.

Why should I use it?  
Use this function when you need to add strengthening ribs to a plastic part.  
Where do I find it?  
Modeling-> Insert–> Plastic Feature–> Plastic Rib
Plastic Snap Latch  
What is it?  
This new function lets you create a plastic snap latch feature, typically for the purpose of adding a lock to a plastic part.  
To use this function:  
Specify the latch type.  
Specify the match area.  
Specify the corner line.  
Define the projection direction.  
Select the base body.  
Specify the location of the latch.

Where do I find it?  
Modeling-> Insert–> Plastic Feature–> Plastic Latch
  
Taper Enhancements for Casting  
What is it?  
A new Body Taper function supports the casting process.  
Body taper (also called double-sided taper) involves the tapering of faces on both sides of a parting sheet or datum plane. You can make these tapers match at the parting by selecting the Match taper option. You can also use a body taper to create three types of tapers:
Double sided tapers – Used for faces that cross the parting sheet/datum plane. These faces will be split by the parting and the resultant halves will be tapered in opposite directions.
  
Undercut tapers – Used to cover undercut regions in the body.
  
Highest Reference Point tapers – Used to taper faces, using the highest reference point on the face.
  
To create a body taper follow these general steps:  
From the Body Taper dialog choose either the Edge or Face creation method.  
Specify the objects for the various selection steps.  
In the case of undercut tapers, you don’t need to specify a parting entity.  
To create tapers using highest reference point select the Highest Reference Point option.  
For double-sided tapers, based on the method of taper creation, specify two sets of edges (one on either side of the parting) or faces to be tapered. If you specify edges, they should satisfy the following constraints: they should not cross the parting; they should either be connected end to end or they should be such that the taper surfaces created from the edges can be trimmed by the body.  
The same Body Taper dialog is used for both creation and edit. However, when you are making modifications, you can only change the angle of draw or the match option, or switch between double-sided taper and highest reference point taper. To modify the selected objects use the Redefine Feature in the Model Navigator.  
Why should I use it?  
Use body taper features to prepare the concept part for molding and casting. These types of tapers have significance from the manufacturing process perspective and as such are best used after the concept part has been prepared.  
Where do I find it?  
Creation: Modeling-> Insert-> Feature Operation-> Body Taper  
Edit: Modeling-> Edit-> Feature-> Parameters  
The edit dialog is also accessible through MB3 on the feature in the Model Navigator. This feature also supports redefine (rollback edit), accessed through MB3 on the feature in the Model navigator.
Selection Intent and Section Building  
What is it?  
Selection Intent has been added to most Modeling features that select multiple curves, edges and faces. In addition, a new Section Builder tool can be used in parallel with Selection Intent for features that require a profile. (Selection Intent was formerly known as Smart Collectors, and was first introduced in V18 for the Taper function.)  
You use these tools when creating and editing features. First set an appropriate collection method in the Selection Intent Toolbar during object selection of an enabled feature. Then select the base object or objects to define the collection.  
Why should I use it?  
These tools let you define your intent at a high level. Not only is selection more efficient, you also increase the robustness of updates during edits by relying on higher level entities that capture your intent instead of low level curves and topology.  
Where do I find it?  
Most Modeling features that previously selected multiple curves, edges and faces now use Selection Intent and/or Section Building.  
For example:  
Modeling-> Insert-> Form Feature-> Extrude  
Modeling-> Insert-> Feature Operation-> Edge Blend  
Modeling-> Insert-> Free Form Feature-> Styled Blend  
Refit Face  
What is it?  
Refit Face is a new editing tool that lets you modify an aesthetically displeasing face to produce acceptable results while maintaining close tolerance with the original geometry. You can modify the data size of the resulting geometry by specifying new values of degree, patch count and tolerance.  
To operate:  
Select the face to refit.  
Select the refit direction or accept the default.  
Select the refit method or accept the default.  
Specify new values for the degree, patch count or the tolerance or accept the default.  
Check for any fitting errors. If acceptable, use Apply to refit the face.  
Exit the dialog or continue to refit another face.  
Why should I use it?  
Refit can be very useful wherever you have a need to modify existing geometry for any of the following reasons.  
The existing geometry is aesthetically unacceptable.

Sketcher Enhancements - Working in a 3D Context  
What is it?  
Sketcher has a new procedure to let you project curves into a sketch. This replaces the old Add Extracted Curve to Sketch function.  
The process is the same as that used by the Add Extracted Curve to Sketch function, except that you can now project a curve non-associatively into a sketch. You can also remove the associativity of a projected curve in the sketch.  
Why should I use it?  
Use this function to project entities onto the sketch plane and to solve and define a sketch.

Sketcher Enhancements - Spline by Points and Poles  
What is it?  
Sketcher now has two new methods for creating splines:  
Spline by Points.  
Spline by Poles.  
Simply select screen locations to indicate the defining point or pole locations. Before exiting the dialog you can make adjustments to the spline shape by dragging the point or pole handles.  
Why should I use it?  
Spline creation within Sketcher now provides immediate visual feedback, and is more interactive and easier to use than the traditional spline creation methods.  
Where do I find it?  
Modeling-> Sketcher-> Insert-> Spline by Points or Spline by Poles  
Sketcher Enhancements - Rectangle  
What is it?  
Two new methods for creating rectangles in the Sketcher are now available.  
Use these new creation methods to indicate an angle at which you would like to create a rectangle. After selecting one point to start the rectangle creation, indicate the angle by specifying where the second point is located.  
Why should I use it?  
This function lets you create rectangles that are not parallel to XC and YC. This relieves you of having to use the Profile or Line function to create such rectangles.  
Where do I find it?  
Modeling-> Sketcher-> Insert-> Rectangle  
Sketcher Enhancements - Dimension  
What is it?  
The process of creating and editing dimensions in the Sketcher is now done without using dialogs. And, you can perform both of the operations at the same time.  
To create dimensions choose the Sketch Dimension icon option and then select the geometry on which you want to create dimensions. To edit dimensions, select the dimension.  
Why should I use it?  
These enhancements let you create dimensional constraints to fully define a sketch. You can easily edit the dimensions to modify a sketch.  
Where do I find it?  
Modeling-> Sketcher-> Insert-> Dimensions.  
Note that both Dimensions and Create Constraints have been moved from the Tools-> Create Constraints menu to the Insert menu. In addition, Create Constraints has been renamed Constraints.  
Sketcher Enhancements - Filleting of Splines, Conics, and Projected Curves  
What is it?  
All supported curves in the Sketcher that include Splines, Conics, as well as Projected (Extracted) Curves can now be filleted.  
Why should I use it?  
This enhancement lets you fillet all curves in the Sketch.  
Where do I find it?  
Found in the Sketch Task Environment under Insert-> Fillet.  
Sketcher Enhancements - Normal Snapping for Line  
What is it?  
During creation, Lines snap normally along their length to the short listed curves, including Lines, Arcs, Ellipses, Conics, and Splines.  
Why should I use it?  
Enhances constraint inference during curve creation.  
Where do I find it?  
Available in the line creation function inside the Sketch Task Environment.  
Sketcher Enhancements - Suppress Constraint Inference in Curve Creation  
What is it?  
Constraint inference can now be suppressed using an accelerator key during curve creation.  
Why should I use it?  
You can quickly suppress constraint inferencing without having to go into the Infer Constraint Settings dialog.  
Where do I find it?  
On UNIX the accelerator is <CTRL> + <ALT>.  
On Window the accelerator is <ALT>.  
Sketcher Enhancements - Tangent Snapping for Line, Arc, and Circle Along its Length  
What is it?  
During creation, Lines, Arcs, and Circles snap tangentially along their length to the short listed curves, including Lines, Arcs, Ellipses, Conics, and Splines.  
Why should I use it?  
Enhances constraint inference during curve creation.  
Where do I find it?  
Found in all curve creation functions inside the Sketch Task Environment
Show Poles  
What is it?  
This button lets you display the control polygon structure of any B-surface or Spline.  
To operate:  
Select any surface or curves.  
Choose Show/ Hide Poles from the Analyze shape toolbar.  
You can also select the display of control polygons while creating or editing any feature that includes the output of a B-surface. This includes Deform, Transform and Match Edge.  
Why should I use it?  
This option lets you examine the control polygon structure of a surface anytime without having to open the Info-> B-surface option.  
Where do I find it?  
Analysis --> Show Poles, or "Show Poles" from the Analyze Shape toolbar.  
X-Form Enhancement  
What is it?  
The X-Form function has the following enhancements to allow quicker access to its most commonly used features while increasing its overall functionality.  
Settings are now retained through out the current session.  
Falloff on selected poles has been added. This lets you deform a selected set of poles while influencing concavity and convexity.  
Falloff is most useful when trying to deform a curve or surface to more accurately match a scan or section. Falloff works while translating, rotating, scaling or editing and maintains the slope/curvature, thus allowing finer control over the transition shape of your curves and faces.  
You can find falloff under the X-Form advanced options.  
You can now snap while working in a constrained direction.  
One example of how this is useful would be when trying to line up poles to an existing curve end, but only in a specific direction. Select the direction you would like to align the poles in and be sure to have snapping turned on.  
A tool for incremental step has been added. This lets you move, rotate or scale by specified increments.  
Stepping is quite useful when moving small distances, or for moving a known distance. To use step you must have a constrained direction set, and be in either the rotate method or in the scaling method while using a discrete vector.  
Redo has been made available while in the X-Form tool. You can find it on the MB3 pop-up menu just above Undo. You are allowed 10 redo steps.  
An option to change degree/patch has been added to let you refit surfaces with either a precise increase in degree or an approximate decrease in degree.  
This can be helpful in reducing the number of patches, or in increasing the amount of control in the face, without changing the degree of the face. The fewer the number of patches the less likely it is that you will have unwanted inflections.  
Context sensitive MB3 radial menus have been added to X-Form.  
These allow accelerated access to some of the most common options, such as editing direction and raise/lower degree.  
Why should I use it?  
These enhancements increase the overall ease of use of X-Form. The dialog now requires less interaction to accomplish required tasks.  
Where do I find it?  
Edit-> Free Form Feature-> X-Form
Grid Section Analysis  
What is it?  
You can now select faceted bodies in Grid Section Analysis.  
No changes have been made to the current Grid Section Analysis dialog.  
Why should I use it?  
When you use faceted bodies for reference from which to design models, you can now analyze the faceted bodies through Grid Section, and create section curves at key locations.  
Where do I find it?  
Analysis-> Grid Section, or from the Analyze Shape toolbar, choose Grid Section Analysis.  
Match Edge Enhancements  
What is it?  
Match Edge has the following enhancements:  
You can now lock the opposite edge when matching surfaces, and can make the opposite edge free or hold the opposite edge up to G3 continuity.  
There is improved indication of when selections are made for both match and reference surfaces.  
You now have separate control for the edge conditions (iso u,v, perp, etc.) for each corner of the patch (Start and End of the edge).  
You can now fix either end of the control rows for position (G0). This effectively lets you lock one or both of the edges perpendicular to the edge you are matching while keeping the interior poles free to move according to the other settings.  
There is now a Projection option under the pole movement item in the pull-down menu. Using this mode lets you move the poles by the minimum amount possible to achieve a required match.  
There is now an option to force a linear change in the length of the mesh segments from edge to edge of the rows being matched. This is provided under the "pole movement" item in the pull-down menu.  
You can now specify a vector along which all adjusted poles will travel.  
You can now perform G3 matching.  
You can now match as a feature.  
A new user interface provides an efficient workflow for improved productivity:  
Improved interpretation of match results.  
A clear and consistent indication of what options are in use and respective settings for them.  
Dialogue controls are now on a single layer.  
Use of handles to support usability and accelerated workflow.  
Why should I use it?  
This release sees significant enhancements to the usability of Match edge, while at the same time providing many more options to control the result.  
Where do I find it?  
Edit-> Free Form Feature-> Match Edge  
Mirror Display  
What is it?  
The Mirror Display analysis lets you view a mirrored image of current geometry across a defined mirroring plane.  
To select the mirror display, click the mirror display toolbar button. You can quickly do this at any time.  
To set the mirroring plane choose the mirroring plane option button from the toolbar. To change the plane, drag the plane definition handle.  
Why should I use it?  
By selecting the mirroring display while designing one side of a symmetric model, you can see the mirrored results immediately while adjusting the shape. This will help you balance the shape across the center plane, or adjust the shape so that each side will form a smooth transition across the center plane.  
Where do I find it?  
Analysis-> Mirror Display, or from the Analyze Shape toolbar, select Mirror Display  
Non-Proportional Zoom  
What is it?  
Non-Proportional Zoom lets you exaggerate the spatial relationships on an entity for visualization and editing purposes, by stretching the view in one direction.  
You can select the non-proportional zoom by clicking the option on the toolbar button at any time. When selected, you can drag a box around the area you would like to zoom in on.  
To return to the normal view deselect the toolbar icon.  
Why should I use it?  
When you are designing a part that is largely flat, use Non Proportional Zoom to accentuate the curvature in one direction, to let you better evaluate minor undulations over a large area, which are harder to see in the normal view ratio mode.  
Where do I find it?  
Analysis-> Non-Proportional Zoom or from Analyze Shape toolbar, select Non-Proportional Zoom.  
Styled Blend Radius Constraint  
What is it?  
A new Radius Constraint option has been added to Styled Blend that lets you specify a minimum radius over the entire region of a blend surface, or a constant radius at the nose of the blend.  
There are three options you can use for the Radius Constraint: None, Min, and Peak.  
Choosing None produces the same result as that in Unigraphics NX 1 styled blend.  
If you choose Min or the Peak option you can specify a constraint value. For the Min option, this value is used to ensure that no region of the blending face has a radius value smaller than the given value. For the Peak option the constraint value is used as a constant radius along the peak of the blend face.  
Why should I use it?  
The Radius Constraint lets you create blends that meet design and manufacturing criteria, by constraining the blend with necessary radius values.  
Use the Radius Constraint ?Min option if your blend needs to achieve a certain minimum radius, either due to safety regulations or tooling considerations.  
Use the Radius Constraint ?Peak option if your design requires a constant radius value along the nose of the blending surface.  
Where do I find it?  
Insert-> Freeform Feature-> Styled Blend  
or from Freeform Shape toolbar, Styled Blend  
Highlight Line Analysis  
What is it?  
The Highlight Lines analysis lets you evaluate the aesthetic form of a model. There are two methods of generating Highlight Lines, reflection and projection.  
Reflection recreates the way a simulated set of tube lights reflect at you when positioned in a fixed location. The reflection lines dynamically update as you rotate the model in the graphics window, allowing you to make crucial design decisions.
  
Projection maps a simulated set of tube lights to selected faces, but does not reproduce the reflections. This is useful for evaluating the consistency of shape in a set of faces, or for evaluating the geometric quality of surfaces by easily locating depressions in faces or discontinuities between faces.
  
Both the reflection and projection methods include options to create the lights uniformly, through selected points, or uniformly between two selected points.  
Uniformly lets you define the number of lights and the spacing between them.  
Through selected points lets you create Highlight Lines exactly at points of interest.  
Between selected points lets you select two points that define a range. The number of lights you specified are then created between the selected points.  
Why should I use it?  
Highlight Line Analysis is an extremely useful tool for industrial designers creating aesthetic surfaces. During the creation of Class A surfaces the need arises to evaluate the way in which light flows across a set of faces or how faces will reflect light. This is a mandatory check of surface quality as well as a necessary set of tools for the creation of aesthetically correct surface form.

Snip Surface  
What is it?  
The new Snip Surface function lets you break a surface at a specific point or snip off unneeded portions of a surface.  
If two or more sheets that need to be matched overlap one another considerably, then you can snip the sheets to bring their edges close enough to enable good matching. In such cases, snipping can provide an alternative to trimming.  
This function works by modifying the topology and the geometry of the input sheet. The resulting surface is a new bounded surface with a modified control point structure.  
To operate:  
Select the face to be snipped.  
Select the Bounding objects (these can be curves, strings of curves, and planes).  
Specify the region to be kept.  
Apply to accept the result or use one of the Refit methods to refit the newly created snipped surface and accept the result.  
Why should I use it?  
It is useful to use Snip Surface to cut or break a surface in cases where you expect to use the new surface as an input to another operation. As snipping modifies both the topology as well as the geometry of the new surface, it is possible to use it for options such as Match Edge and X-form.  
Snip Surface has proved useful for surface creation using the Control Point Edit method. Trimmed sheet does not provide this ability.  
The only limitation with Snip Surface is that, unlike a trimmed surface, a snipped surface cannot be unsnipped.  
Where do I find it?  
Edit-> Free Form Features-> Snip Surface
Assembly Arrangements  
What is it?  
You can define assembly arrangements to specify alternative positions for one or more components in your part, and store those alternatives with your part. An arrangement determines:  
The position and orientation of the immediate child components  
The Variable Component Positioning (VCP) of any subcomponents  
The Used arrangement for each immediate child component.  
The system automatically creates an arrangement (and sets it as both the active and the default arrangement) when:  
You have not created an arrangement by the time you add or create the first component in a new part.  
You convert a pre-Unigraphics NX 2.0 part.  
Two new arrangement-related columns in the Assembly Navigator are:  
Arrangement -- this column specifies the Active arrangement for the displayed part. For each component in the assembly, it specifies the Used arrangement.  
Arrangement Specific -- this column indicates whether the component is "arrangement specific," which means that you want to force edits to happen in that particular arrangement.  
Several arrangement options are on the new Arrange cascade menu, which is located in two places: the graphics window pop-up menu and the Assembly Navigator pop-up menu. The Arrange cascade menu contains:  
Arrange Position toggle -- if this is toggled OFF, you will receive a warning that arrangement-specific edits will be deleted for the selected components.  
a list of arrangements in the part -- you can select one to make it active.  
Edit Arrangements -- which brings up the arrangements dialog to let you edit arrangements in the selected components. This option is also located on the Assemblies-> Components menu.  
Many arrangements can now be created and updated based on the loading of I-DEAS Assembly Configurations from .xpk files. When Unigraphics NX part files are loaded into I-DEAS, only the currently active arrangement is loaded into an I-DEAS Assembly Configuration.  
Why should I use it?  
Arrangements let you switch easily between different alternative component positions in your assembly. You can save as many arrangements as you need, which keeps you from having to individually specify the variable positions that you want to reference when you open your assembly.  
Where do I find it?

Assembly Navigator Preview Panel  
What is it?  
The Assembly Navigator preview panel is an expandable area of the navigator that displays the stored preview of loaded or unloaded components. This helps you open the exact part that you need.  
Open the Assembly Navigator and select any component. To view a preview, click the Preview banner displayed at the bottom or side of the navigator. You can leave the view expanded, and browse the assembly component-by-component.  
Why should I use it?  
When you are working with a large assembly, you can use the Preview panel to open only the parts that you need. This keeps the memory usage low for better performance.  
You can also use the Preview panel to make sure that parts have reasonable previews, or to simply view the components in your assembly for better understanding.  
Where do I find it?  
At the bottom or side of the Assembly Navigator (which you open with the Assembly Navigator tab)  
Assembly Navigator Dependency Browsing Panel  
What is it?  
The dependency browsing panel lets you view the dependencies in a selected object within your part or assembly. The panel, which is a special extension to the Assembly Navigator and the Part Navigator, replaces the Object Dependency Browser and the Information-> Feature functions.  
The dependency panel handles components, parts, and assembly constraints for the Assembly Navigator.  
Dependency information for the selected object's node includes:  
Parents -- objects that the selected object depends on  
Children -- objects that depend on the selected object, or objects generated by the selected object (such as members of an instance array)  
You can click the Detailed View button to check relationships at the edge, curve, or assembly constraint level.  
You can use the Forward and Back buttons to navigate between the dependencies of the most recently selected objects.  
Why should I use it?  
You can use it to analyze the potential impacts of a planned modification to your part or assembly.  
Where do I find it?  
At the bottom (or possibly the side) of the Assembly Navigator or the Part Navigator  
Assembly Subsequences  
What is it?  
You can now create subsequences restricted to a particular group of components in an assembly.  
You can also refine a sequence step that assembles or disassembles a group of components in order to reference a particular sequence for that group.  
Why should I use it?  
You can use it when you need to create a sequence for a limited group of components within an assembly, rather than using all the components.  
This functionality is also useful when you want to define one or more sequences within the context of a larger sequence.  
Where do I find it?  
In the Sequence Navigator, commands for subsequences are on the pop-up menu of a Step node that assembles or disassembles a group of components.  
In the Assembly Navigator, you can create a sequence specific to a particular component group by using the pop-up menu on a Filter node (that contains those components) in the Filters in Part folder.  
Deformable Components  
What is it?  
Deformable components have been enhanced in the following ways:  
The lightweight reference set for components that have been promoted or deformed now displays a facet of the promoted or deformed geometry (rather than the original geometry, as previously).  
You can now deform a component in an assembly when the deformable component and the assembly use different units. The units of the deformable component are automatically converted when you deform it. (You will receive a warning message before the conversion occurs.)  
You can use the new Deformed Component Open API to automatically create deformed components.  
Why should I use it?  
The lightweight reference set can have significant performance improvements over more detailed reference sets (such as the model reference set). The other enhancements let you use deformable components in assemblies where you could not use them before, and increase the methods you can use to create them.

Tools-> Define Deformable Part  
Assemblies-> Components-> Deform Part  
Improved Display Property Synchronization  
What is it?  
When you use copy display properties from subassemblies to assemblies that use those subassemblies, the copied properties now include:  
Materials  
Textures  
Individual object (such as a face) properties that will now be copied onto the corresponding assembly object  
Previously, only colors, translucency, partial shading, layer settings, and attributes on components were copied.  
Also, when you create a non-master part, display properties are now automatically synchronized from the master to the new non-master. Any objects that are blanked in the master will be blanked by default in the non-master, and the non-master is created with the same viewing direction and scale as the master. This lets the non-master match the appearance of the master as much as possible.  
This is not supported for non-masters in UG/Manager or functions where non-masters are created automatically (such as template drag and drop).  
Why should I use it?  
When you copy display properties, more types of properties are now copied, increasing the synchronization between the original objects and the corresponding objects.  
Where do I find it?  
The Display button in the Synchronize Subassembly Properties section of the Assembly page in the Component Properties dialog  
Mate B-Surfaces  
What is it?  
You can now select B-surface faces, such as parametric or swept surfaces, for mating.  
Where do I find it?  
Assemblies-> Components-> Mate Component  
Mirrored Assemblies  
What is it?  
You can now mirror an assembly with respect to a plane. Use the options on the Mirror Assemblies wizard to specify the details of the mirrored assembly.  
Components must be children of the work assembly to be selectable for the mirrored assembly.  
You can reposition components so that they appear in a different location in the mirrored assembly.  
You do not have to mirror all the components; you can specify components to be excluded.  
Why should I use it?  
Often assemblies are really one side of a fairly symmetric larger assembly, such as the right or left side of an automobile. After you have created one side, you can use the mirrored assemblies functions to quickly create the opposite side.  
Where do I find it?  
Assemblies-> Components-> Mirror Assemblies  
Parts List Relocation  
What is it?  
The Parts List functions have been removed from the Assemblies pulldown menu. You can now create a parts list from inside the Drafting application by choosing the Parts List folder on the Tables palette.  
Where do I find it?  
see Parts List in the Drafting section for more information  
Save Work Part Only  
What is it?  
When your work part is an assembly, and you want to save the work part -- but not any of its components -- you can use the new Save Work Part Only option.  
Why should I use it?  
Use this option when you want to save your assembly work part, but not any modifications to its components. For example, you might use this option to save time in a large assembly if you do not yet need to save the changes at the component level.  
Where do I find it?  
File-> Save Work Part Only  
Scripts  
What is it?  
The scripts functions have been relocated to Assemblies-> Advanced-> Scripts. The old-style component filters options (which are obsolete since filtering functions were moved to the Assembly Navigator) have been removed from the dialog, and the dialog has been renamed Scripts.  
If you need access to any existing old-style component filters, you can locate and edit them in the Assembly Navigator while it is in filtering mode.  
Where do I find it?  
Assemblies-> Advanced-> Scripts  
Annotation Origin/Leader Definition  
What is it?  
A new Annotation Placement toolbar provides a quick, dynamic way to choose origin and leader placement when creating annotation. The new interface:  
Infers the leader type to create.  
Infers the alignment method based on the object preselected.
