Hi Clark
BTW, What's in your planning hopper for TF Rubies? I really appreciate your hard work and commitment to SU modelling and sharing this with us.

I will add one wish list item. SU deals with surface modelling only and not as a solid?
Is there a method to convert an SU TF model into a solid equivalent.(dxf,dwg or
other software?)
Cheers
