mass and density components in family table

[kertus]

Bye to all,
I have commercial components reproduced in family table and I need to close this in the morning so I need your kind help

I do not want to declare the material, but manually provide the value of the mass to datasheet and indirectly calculate the density value using the volume I create automatically calculates as "reported property mass " (pro_mp_volume).
I did as follows:
-) in the mass properties I went to "alternated mass" and I popped the parametric voice.
-) I put in family table the pro_mp_alt_mass parameter, manually inserting mass values for each instance of the family table
-)I wrote the following report for density (in practice the ratio between the mass defined by me and the volume of time calculated)
mp_density=pro_mp_alt_mass/pro_mp_volume

the problem now is that, if I go to calculate the mass "computed" he always takes to reference the calculated volume of the parent component of the family table, and then he screws the calculation of the inertial properties because I fake the density of the component.

Can you tell me where I'm wrong?

I also tried to use the pro_mp_alt_volume parameter by forcing the system and writing pro_mp_al_volume=pro_mp_volume (since in the calculation of mass properties "computed" makes use of the "alternated" quantities)
I also tried using mass and volume parameters from but introduced and writing mp_denisty =mass/volume where mass=pro_mp_al_mass and volume=pro_mp_volume......but none of the methods to be matched.

if you decide that the mass commands on the calculations, you do not have to relate the density, but you already have it with pro_mp_alt_density.

hi 320i, that parameter on my creo 2 is mp_density. so you say that as pro_mp_alt volume take what calculates I create automatically (i.e. pro_mp_volume)?

Yes, you do not have to enter further relationships when fixing mass or volume or both, the density is calculated accordingly by the system.
were the old pro-e who needed an additional relationship, already from wildfire 3 (or perhaps even from 1) it is no longer necessary

I try as soon as I'm in front of the pc and I'll tell you grit for now

I tried 320 i but what I feared happens. I'll get you some pictures.
I removed the relationship and put only the pro_mp_alt_mass in family table to insert the mass from datasheet. in case 1 sees the right foeume and I get a right density. in case two if I make the mass ratio on volume indicated in the mass properties does not come that density value. Moreover the volume would not be even that because in the case 2bis I bring back the pro_mp_volume that should consider for the calculation, according to what you say (default without report).

Can you help me figure out where the bug is?

Thank you.

attention I create makes a mere mathematical calculation, if you expect certain values and these do not come to you, it means that there is a mistake in the data you enter (or those calculated with the volume of mathematics).
have you tried instead to move from the mass, to the density?
