How to get Mass/Area/Volume of a Comp in a macro

Hi everybody,

does anyone how to get the area / mass / volume of a component in a macro?

I'm searching for anything like:

' set area [hm_getcomparea $comp] '

or structural / non-structural mass or volume of this component.

I need it especially for Nastran models, but it would be great to have a solver-independet way (for at least: area, volume and total mass).

Can anybody help me?

Thank you...
