Weight definition problem in B.I. Essentials

Hello,

On an Assembly design, I'm running the weight definition in the B.I. Essentials in order to define and export the weight properties of the assembly. I've updated all the properties last week and saved (the weight properties were in computed or declared) but when I run the weight definition today all the information is a missing state.

Does somebody have an idea on this problem?

I've tried:

  • To extend the design tree to load the 3D shape of each object. 
  • To make updates (global update, characteristics update, global refresh, and the weight update in the BI essentials).
  • Use "switch to Product" on bodies but it doesn't change anything. ​
