So I'm working on a project and we created a rim lock system for a lens to connect on. In the picture shown you can see the bottom frame has a rim and the top part has the slot for the rim to connect in. I made the rim and slot by making a 3D sketch around the structure and then used sweep boss/cut. But for some reason I am struggling to make them line up so they can connect in the assembly. Anyone have any tips on how to make them line up and fit together perfectly? Thanks a lot for all the help, I appreciate it.
