(I think this is the best place for this since it seems to me that the surfacing community usually has some extra tricks up their sleeves):
I would like to cut a body with a surface that is moved along a profile. I could sweep a surface but it would have only a 2d profile, i'd like to take a 3d profile and sweep it to generate a new surface that I can then use to cut a body.
I'm looking for a way to cut a body with another (surface) body that is tracking along some motion path. Two examples I can give are the following:
1) I'm making a part that wants to snap to itself. It has a 90degree rotation followed by a 180 rotation (think two open scissors). However, the snapping path is not along the shared axis of the objects but rather it operates in another specified direction.
2)I want a custom gear/cam profile. I have a custom "saw-toothed" rack and I would like to roll a wheel along the length of it and cut away the wheel with the shape of the rack.Something like this: http://mathtourist.blogspot.com/2011/05/riding-on-square-wheels.html Alternatively I'd like to generate a tooth profile such as a cycloidal gear where the tooth shapes are not rolling but tracking a path in and out of the teeth.
