I saved an assembly as a part. It has more than 1000 bodies and surfaces at this point. Made hundred or more features yet. It is sized over 400 mb. I want to make this smaller and easier to work with. Right now, it is tiring just to do an extrude if it succeeds. My job is to merge all bodies but there are gaps between them, so I am filling them manually. It is gonna be 3D printed.
What can I do to make this part smaller and lighter?
