Thanks Box!
I've got it sorted. I appreciate your time in walking me through the process. A few more questions for you.
First, do you know if CNC milling machines can reset dimensions in the same way you've described for .stl printing files? I'm not sure what's required at the machine, but fabrication companies ask me for a .step or .iges which I generate from my .stl files with FreeCAD. Perhaps there's a better way to do this?
Second, in order to create the stop chamfer on the edges of the model where there is a radius transitioning into a perpendicular surface (ball-end mill). I have been manipulating a 45 degree face with a radial bending tool to pull off the edge at a point. Then deleting everything except for one welded line as the desired path. Followed by recreating a triangular shape and running the follow me tool. Finally subtracting the solid chamfer shape from the solid body. Is there a better way to do this?
Thanks again for all your help.
