How to create locking features on a split part?
I create a ring shaped part and split it in the plane of the rotation. Now I have two parts (A&B) with identical mating surfaces.
Next I want to create a torus shape (2 in fact one with slightly larger cross section) central and along the line of the original rotation.
Now add one of the torus shapes onto part A, subtract the other from part B to form a circular positional interlock between the parts, once 3D printed.
Sounds good but how do I go about it? I can create the elements but cannot seem to be able to select them for the Boolean operations. Is there a better way to achieve the same effect.
My apologies in case this question has already been asked but I did not know how to phrase search criteria for this condition.
