Thanks Carl, Wow you're were right, is really easy using Blender 3D. I'm using the 1.187 version of CW designer. Do I have to purchase the STL importer add on to make this work? I've got a few add ons with my designer, mostly like centerline text, conforming vectors, and the pattern editor for the probe. I think each one of these were $100 at the time.
Again thanks for taking the time to make this video on making gears in Blender 3D.
