I am making some commonly-used library models. In the case of some of the more complex assemblies, I thought it would save load/open time if I saved the sub-assemblies as parts, so a complex assembly with 91 parts can be reduced to a simpler assembly of 11 parts.
All seemed to be going well, until I checked the mass properties of one of the parts representing a sub-assembly.
It seems that, when I save an assembly as a part, the appearances are copied across, but not the materials. Thus, my new part has a density of 1000g/cc (i.e. 1000 times as dense as water) and weighs the same as a small planet.
In the new part, each assembly part is represented by a solid body. I have discovered that I can assign materials to each solid body, but this takes some time and effort, neither of which I am keen on expending.
Is there a way to copy, automatically, at the time of creation, the mass properties of an assembly into a multi-body part?
