PRO_MP_DENSITY change

I have one catalog part from one supplier, that in it's catalog he says what it's part's weight. He suplies a 3d simplified part, so CREO is unable to calculate it's weight. I'me building a family table with all the family components.

So, is there any way to change PRO_MP_DENSITY to have the final weight of the part, according to the provided part?

Example: the catalog says one family item weighs 3.1Kg, but Creo according to the simplified drawn part, calculates 5.2Kg, so for measuring correctly the assembly weight, e need that part to weighs the 3.1 Kg.

Yes, you can use assigned values.

Well it looks that i still have a problem.

I have made a few tentives to solve this. But no way.

At the moment, I have created a mass properties feature, to calculate the volume of the part, and in initial relations

the following relation.

MP_DENSITY=PESO/VOLUME:FID_VOLUME

"PESO" is the parameter that contains the value of part's weight.

I've inserted this relation in post relations, and there is always requesting regeneration, it looks that it's in a infinite loop of regenerations.

I tried to use, the PRO_MP_VOLUME, but part's weight, isn't according to the parameter that I've created (PESO).

At the moment is working, but I'm having that alert message.
