Attached is an assembly created using Atom3D. I'm not sure if it's entirely self contained so I uploaded the parts files as well. I managed to set the constraints to place the standoffs on the base and I can drag them around just fine but I can't figure out how to precisely place the assemblies on the base. So there is a base assembly, a left set of 4 standoffs that are pinkish, and a right set of 4 standoffs that are orange. For example if I wanted the lower left standoff on the left assembly to be placed at x=6mm and y=10mm how would I do that?
