But I guess it is possible with Solid++. I remember seeing something exciting on their old website - helix around curve even with scaling rail option! (it means the helix diameter, not diameter of "wire", altered smoothly). We want it :) -Petr

Hi Petr, yup there are actually several things that are technically possible but that I have not had a chance yet to create UIs for...

Unfortunately the UI design can tend to be the most difficult part, just having the engine part work is not really the whole thing, although it certainly can help!
