> >Mini-Review of IronCAD 6
> >
> >Although IronCAD LLC has undergone many changes over the years, its core
> >MCAD product, also called IronCAD, has remained the company's
> >foundation. IronCAD made its debut in 1998 and immediately gained a lot
> >of attention by employing innovative dragging techniques for creating
> >and editing solids. In late 2001, the developers premiered the
> >InnovationSuite, which included IronCAD, a scaled down version of
> >IronCAD called Inovate, and TeamVault for PDM (Product Data Management).
> >Last year, InnovationSuite 2002 was released. And just this month the
> >package has been upgraded again. Unlike in the March 2002 CADENCE
> >magazine review in which I covered the entire package
> >(https://www.cadenceweb.com/2002/0302/fr0302.html), in this mini-review I
> >am only going to focus on IronCAD 6 (keep in mind that the other
> >components have also been updated).
> >
> >New Surfacing Tools
> >
> >One of the biggest enhancements in IronCAD 6 is the introduction of
> >surfaces. Actually, the program has had the ability to create extruded,
> >revolved, swept, and lofted surfaces for a while, which I will talk
> >about later on, but Version 6 adds six new surfacing tools.
> >
> >All of these new surfacing tools only work with 3D curves, so let's
> >begin with those improvements. For starters, there is a new option to
> >turn 2D curves into 3D ones. In addition, creating 3D curves from
> >scratch also just got easier due to an assortment of new tools. Two of
> >my favorites are: the ability to reverse a curve's end tangency and the
> >way users insert new points on a spline--albeit there doesn't seem to be
> >a way to delete these new points.
> >
> >After I created my first 3D curve, I selected one of its control points
> >and used IronCAD's TriBall to edit its location. Although the program
> >now has the ability to edit points via X, Y, and Z coordinates, most
> >users will prefer the TriBall, which is IronCAD's dynamic positioning
> >tool. It also can be used to copy the curve with or without
> >associativity. After doing so and tweaking each one, I had three
> >different curves in position. I then used the new Loft command. After
> >the first curve is picked, IronCAD needs to know where to anchor that
> >curve. This means another mouse click is required, which really should
> >not be necessary. However, after that it is just a simple matter of
> >selecting the other two curves, and the software gives visual feedback
> >in the form of a red dashed line. This lets the user know which curves
> >make up the loft and the order that they will be used in.
> >
> >IronCAD still maintains its old way of creating a loft, which acts more
> >like a variational sweep as it sweeps a single curve along another
> >curve, and then asks how many loft cross sections are desired in
> >between. It is then possible to go back and edit the cross sections or
> >the curve that defines the path; however, only 2D curves can be used in
> >this original Loft command.
> >
> >While IronCAD 6 doesn't offer true freeform surface deformations, it
> >does allow you to edit underlying curves normally, and then the surface
> >built off of them will automatically update. Technically, the original
> >curves are not part of the surface, as IronCAD preserves them and
> >essentially uses duplicate curves to make the surface. While keeping the
> >original curves can be handy, I feel this should be an option rather
> >than the only choice because having two curves in the same location
> >sometimes results in selection problems. The software also houses new
> >tools for creating swept and revolved surfaces; although, as is the case
> >with lofting, the old techniques are still available with basically the
> >same differences and limitations.
> >
> >Other Surfacing Tools
> >
> >Mesh is a totally new surfacing tool, and it creates what is commonly
> >known as a UV surface. Mesh takes a grid of curves roughly oriented
> >perpendicular to each other and essentially does a bi-directional loft.
> >The 3D curves used in this tool must be touching wherever they
> >intersect, which is a fairly common rule for most programs (except
> >exclusive surfacing applications such as Rhino).
> >
> >Another new surfacing tool is called Edge Surface, which is known as a
> >boundary or fill surface in most 3D applications. This tool is ideal for
> >closing gaps in imported surfaces, by allowing the edges of the opening
> >to be picked, thus forming a boundary. While this is a nice addition to
> >the IronCAD 6 toolbox, the program is limited to only 3- and 4-sided
> >surfaces. There is a tangency control setting to ensure a smooth blend
> >between the new surface and the old, but this can only be set after the
> >surface is built. Also, when I zoomed in on the result, IronCAD did not
> >create a completely watertight surface, as gaps were still apparent.
> >Oddly, if I turned off the tangency setting, these gaps were alleviated,
> >but then the transition wasn't as smooth. IronCAD also allows surfaces
> >to be thickened into a solid, which is handy, and a surface can be
> >duplicated with zero offset and then moved into position with the
> >TriBall.
> >
> >While these tools help make IronCAD more attractive to the product
> >designer, some tools do need a bit more work as well as more options. In
> >addition, there are commands missing such as surface filleting,
> >blending, extending, trimming, untrimming, and zebra stripe analysis.
> >However, even without any of these tools, IronCAD is still an excellent
> >program for conceptual modeling by virtue of how dynamic dragging is
> >incorporated extensively throughout it.
> >
> >Other Enhancements
> >
> >IronCAD 6 also features other modeling improvements. For instance, there
> >are now more ways to specify a chamfer, and the developers also
> >incorporated several miscellaneous assembly enhancements. The 2D
> >drafting capabilities have also been beefed up with the addition of hole
> >tables, auto ballooning, an aligned section tool, new dimension types,
> >and more.
> >
> >Conclusions
> >
> >IronCAD 6 deserves a look by anyone considering the purchase of a solid
> >modeling program (with integrated PDM)--not so much based on what's new,
> >but what's old. I'm not putting down the new stuff--it is helpful--but
> >the strength of the program is still in its intuitive approach to solid
> >modeling, something no other MCAD vendor has been able to duplicate.
