How to make a creo .prt file have zero density (mass= 0)?

How to make a creo .prt file have zero density (mass= 0)?

I know I can adjust the density value to a min and get a .prt that has a very low density.  But how to make it have zero density?  Like in the case where you have an envelope that represents the movement of a part.  But it in your assembly?

I'm thinking I might try an make the part a surface part.  But finding oyt how to make the density zero would be nice.

Thanks for any help.

I am not sure when the changed happened, but PTC no longer allows densities of 0.

Can you do it in a skeleton part?

If you really want to do this another option might be to find a model made in 2000i (or older release) that has a density of 0 and then rename it, delete all of the features and go from there. I have one so I know at some point in time it was allowed.

You can't even "assign" the mass or density as zero.

I think you are stuck with using a surface model. That's my preference anyway, I use either models with just curves or just surfaces to represent motion.
