Hello all,

By default, when you try to compute the weight of a part made of surfaces using the B.I Essentials/Weight Definition command, the result is 0kg and you get the message "This element consists of surfaces without any thickness". Even if you have applied a Covering Material with a thickness it will not work.

What you need to do is to apply a thickness on the surface(s) using the Thin Part Attribute command from the Generative Shape Design App. 

Then you will be able to compute the weight of the Part using maybe a Covering Material or a Core Material.
