Re: [CAD_CAM_EDM_DRO] threads in 3D CAD

Steve,
 
Though not parametric, you can model a thread in Rhino by sweeping a curve along a helix.   It isn't as easy as I would like but it can be done.

Subject: [CAD_CAM_EDM_DRO] threads in 3D CAD

 
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
