Hello, I'm learning SW and I'm not sure if I'm going about this correctly or not, but I have an imported 3D model that I have split using a Planar Surface. I then used the Move/Copy tool to separate the 2 bodies, filled-in surfaces the open sides and knitted them. Then I've added 2 male pin extrusions on one body but I'm having trouble figuring out how to subtract the matching female pin holes on the other body and move the bodies back together.
