Copying CATIA Version 4 Model Data to CATIA Version 5
This task shows you how to copy the specifications or geometry of a CATIA Version 4 model to CATIA Version 5.
The following data can be copied from CATIA Version 4 to CATIA Version 5:
surfaces (both polynomial and BSpline)
faces
volumes
skins and exact solids
mockup solids (see remarks regarding copy/pasting mockup solids below)
polyhedral surfaces and solids
circles
ellipses
points
lines
planes
clouds of points
edges
parabolas
hyperbolas
curves (both polynomial and BSpline)
CCVs
NURBs (curves and surfaces)
PIP elements (Tubing)
GPR elements (AEC Primitives)
STR elements (planar structures, linear structures)
The following task describes how an entire model is pasted from Version 4 to Version 5. You can also select the geometric elements listed above and insert them into an already existing Version 5 document.
Open the document LAMP.model.
You should have already completed the task Checking CATIA Version 4 Model Data Before Copying It to CATIA Version 5.
You may want to customize certain settings before proceeding with this task. For more information, see Customizing Compatibility Settings.
Open a new CATIA Version 5 CATPart document. To do this, refer if necessary to "Creating New Documents" in the CATIA - Infrastructure User's Guide.
In the specification tree or geometry area where the Version 4 model is displayed, select the geometrical element or elements you wish to convert.
If you intend to copy the geometry you can either:
drag and drop the element(s) onto the appropriate location in the CATIA Version 5 document. The cursor changes slightly i.e. the symbol appears indicating where a drop is allowed. If the cursor changes to the symbol , the drop is not allowed in that location.
or:
a. Put the element(s) you have selected in the clipboard by clicking the Copy icon , select the Edit->Copy command or select the Copy command in the contextual menu.
b. In the specification tree of the CATIA Version 5 document, select the appropriate item (for example, PartBody or Body.1, Body.2, etc. in the PartDesign workbench).
c. Click the Paste icon or select the Edit-> aste command or select the Paste command in the contextual menu.
This operation recovers the specifications previously put in the clipboard.
If you intend to copy the specifications:
a. Put the element(s) you have selected in the clipboard by clicking the Copy icon , selecting the Edit->Copy command or selecting the Copy command in the contextual menu.
b. In the specification tree of the CATIA Version 5 document, select the appropriate item (for example, PartBody or Body.1, Body.2, etc. in the PartDesign workbench).
c. Select the Edit->aste Special... command or select the Paste Special... command in the contextual menu.
The dialog box below appears:
d. Select CATIA_SPEC and click OK. This operation recovers the specifications previously put in the clipboard.
Click the Update icon to view the copied data or use Edit -> Update.
You may want to click the Fit All In icon to fit all data in the window.
Notice that the toolbars change depending on whether a CATIA Version 4 model or a CATIA Version 5 document is selected.
If you copied the geometry the result should look something like this (using the Window->Tile Horizontally command):
If you copied the specifications the result should look something like this (using the Window->Tile Horizontally command):
Bear in mind the following when copy/pasting:
The migration of V4 model data to a V5 document generates a report (.rpt) file named after the model migrated:
on Windows: in C:\Documents and Settings\jdy\Local Settings\Application Data\DassaultSystemes\CATReport
on UNIX: in /u/users/username/CATReport
But this depends on the path setting in env file.
If you used the CATIA_SPEC option mentioned above note that only the paste operation is included in the report i.e. the actual update of the CATPart document is not taken into account.
For more information about the usage of the V4/V5 BREP Info Checker, please refer to Comparison of Result Option in Batch: V4/V5 BREP Info Checker.
When copy/pasting mockup solids : If the solid has a history then the V5 specifications are created. However, if the solid has no history or if the CATIA_RESULT option is selected (using the Paste Special... command) then a cgr file is generated containing the visualization information of the solid. The name of this file is "mymodel_SOLMxxx" and is located in the same directory as the V4 CATIA model. This file can be inserted into the Product Structure application.
When copy/pasting sets of surfaces : If you want to get a unique surface in V5, it is more efficient to perform the join in V4 before the migration than in V5 on the resulting surfaces.
