Hello Jerry

As to exporting to STL both Silo and Blender will export to that format. Personally I feel that Blender would be the more robust of the two ...

I second the motion, and not just because I'm a Blender-phile. I have the latest Windows and Linux versions of Silo: there are still issues. Tried both flavours on two widely different systems: Silo still locks up on me and/or crashes in certain situations. Which is a pity, as I was using it to do Fugazi's modelling tutorials... now, I'll have to sort out how to do what Fugazi does in Blender. And Silo just does certain things differently.
