density of extracted body changes in multibody part
density of extracted body changes in multibody part
(OP)
Hello all,
I have some multibody parts where 1 body is derived from another via the extracted body feature.
Both bodies have different solid density assigned.
Now every time any feature in the part is changed, the extracted body inherits again the density from the originating body, throwing my weight calculations out of whack.
Same thing happens with material assignments.
Is this intended behavior or a bug.
And does anyone have a workaround?
Thanx
PS, working with NX7.5

Sorry about the missed word in the question

thanks for your reply.
The model in question is a complex shaped exhaust muffler , partially filled with mineral wool.
To model the wool and calculate the weight I made an extracted body of the muffler body and added some features ( offset , trim , .. ).
You are saying the extracted body , by definition has the same density, I don't agree.
I am able to assign different density and even different material assignment to the different bodies.
If the densities were by definition identical, I should be able to do this.
Problem is that after a change the density is reset to the original density.
Does that make sense?
bye

But for now I have one question about the company that you are at . . . A long time ago was it based out of Racine, WI ?

I'm actually based in Europe working for one of the big worldwide exhaust suppliers.
