I'm trying to make a simple mold by combine/subtracting one part from another. I had it working the other day, but I had to start over again, and now I can't figure out how I got it centered inside the box. Is there something better than the insert feature/ move/copy?
If both parts are created symmetric about the reference planes, those planes can be used for location.
