Inertia data Wz to calculate tau stress in a torsion of a beam.

[gusi_cl]

I've spend a lot of time to try to insert inertia data Wz automatically in a custom profile.

If you use a profile standard generated from the inventor content center this data is inserted correctly and automatically compare in the section properties of the beam. Thia is usad correctly in IFA and in Inventor Nastran too.

Creatina a simple beam with same dimensions, this property is Wz=0 and non calculated automatically.

Other data are comparables.

I tried to insert this Wz in a column in the tables of the family in Content Center, serching in .xlm files in Design Data but nothing change.

Can someone help me? Alternatively I have to insert all data manually...
