I have an assembly that all parts are constrained to and centered on the Origin. All of the sub assemblies, and parts in the sub assemblies are also built around the origin, but they do involve imported bodies from 8020. When I add a constraint, it moves the parts as far away as is possible. When I do a zoom all, the main assembly is a spec in the corner, and I can't even find the part that flew to the other side of the world.
Is there anything I can do to change this behavior? Is there some "best practices" that I'm not following?
