I notice some parts had a material applied to their body and thus mass could be calculated.
But when inspected with B.I Essentilas "Core Material definition" they appear as incomplete.
Applying the material to the 3D shape or part solved this but I want the material to be applied to the Part Body.

1. What use is there to "defining the material"?
2. Is there a way to recognized material that are already applied in on the body by the "Core material definition" in order to get the "Material definition complete" status?

3. Any trick to do this in batch?
