[IFC] weight for an element from Pset_MaterialCommon

1. A by Arv on 9 Feb 2023, edited 11 Feb 2023 #

   Hi, I am trying to get the gross and net weight for an element instantiated with IfcRectangleHollowProfileDef and IfcMaterial assigned as Aluminum. I have also assigned MassDensity property Pset_MaterialCommon for Aluminum and also added the SI unit for Mass unit.

   However, the weight of the instance is coming as 0.0

   Any idea what is the mistake that I am doing

   I saw this post from @Moult on this subject regarding confusion on IfcMaterialProperties.

   So I guess its not really possible to link the density of the material to get the weight of the object?

   Are you trying to do it with a python script of through the Blender UI?

   This functionality does not exist yet I think. Would you mind filing it as a bug?
