Well, I'm not banning this type of questions from MBDyn's forum, since 
they originated from its use, but I believe they are more appropriate 
for a Blender forum, as there's nothing (at this stage) that is specific 
to MBDyn, and probably only a few MBDyn users can answer them.

At some point, if there happens to be some script that allows to 
generate inertia information from a graphical Blender model, it would be 
nice to be able to automatically convert that info into the data of 
MBDyn's rigid body, but I believe right now this is just another entry 
in the wish list.

Cheers, p.
