Adding Physical Properties to STP Files

[Anonymous]

I'm trying to add some material properties to a STP or IGES file I've received from a customer (in Inventor 2011). Is there any way to add a density for example, so I can obtain the mass of the model? I've tried doing it through the iProperties menu but it's not giving me a mass.

Any ideas/

and are these imported parts composed of only surfaces..hint hint..

Yes, they are imported, surfaces only. Therein is my question: any quick way to convert these surfaces so I can assign material properties?

Yes,
If

the geometry is good - use the Repair or Construction Environment to stitch to a solid.

If it is really good, there might be a set of settings on Options to do this automatically on opening.

if the geometry isn't particularly good you still might be able to repair and stitch.
