threads in 3D CAD

Have you looked at Alibre CAD 3D 2013 $99, they also have a CAM module,
which is I think $800. Older versions 2009/2010/2011 Alibre CAD/CAM,
sometimes sell on ebay for $200-$250 for the pair.

Hello group

Some years ago I took several trade school classes in CNC. The software
was Inventor and Mastercam. Although I knew that I could never afford to own
either, using them in class conditioned my expectations of what software
should do, and I assumed that over time less costly programs would come to
offer similar capabilities.

Getting to the point, IIRC, parametric generation of threads of virtually
any spec was easy in Inventor, and I assumed that some similar, if not so
elegant, capability would be included in any 3D modeling application. Now I
have just learned to my great surprise that Rhino, which had become my aim
to acquire, has no thread modeling capabilities.

So my question is: do most 3D CAD have integral parametric thread
generators, or is this considered a special capability?

TIA
Steve
