How do I create an object with specific insertion points? I'm developing a terrain model with curbs and gutters, walks etc. The Solid Element Operations I used on the meshes are associative. I found the only way to get rid of that association and keep the changes is to save the individual 3d mesh as an object. But, the problem is that I need them to all to fit together and line up somehow. Is there a way to give them all the same relative insertion point?
