Hi all, I'm exploring Mathematica as a tool to design 3D solids. The shape I'm working on now is a cylindric solid with a few cylinders bored out of the side (like screw holes into a cylinder). So far, I've figured out that I can use RegionPlot3D to do this, since the shape specification is a boolean expression. However, since RegionPlot3D is based on sampling, sometimes artifacts show up in the model. Since I have expressions for all the surfaces, I'm thinking that adding / subtracting 3D solids "at the mesh level" would be better. Are there functions in Mathematica to specify 3D solids? For example, a rectangle twisted around a spiral axis (for threading). I'm wondering if anyone has experience doing this kind of thing in Mathematica. I'd love to hear your approach and tools of choice. TIA, Brien
