What material property is rubber in NX

[Jashe]

Im trying to get a mass for rubber parts in NX and I don't see a "Rubber" material within the library. Is there a name they use in place of rubber within the library?

If all that you're looking for is the mass property values, such as the weight, why not just assign the Mass Density for the rubber that you're working with. After all, there is an alternative way to assign a Mass Density to a body that does NOT require that you assign an actual material. Just go to...

Edit -> Feature -> Solid Density...

...and select the solid body and enter the Mass Density using whatever units that you have.

Okay. That works perfectly. Thanks. Now I'm just having trouble picking a another body within the part to change the density on. For some reason it's not letting me do that.
