property part

[nerork]

Hello, guys.
I'll ask you the question.
I have a part with assigned the material.

in the property tab I would like to add, among the parameters, the item "weight".
I would like this weight to be updated independently, so the procedure : add external property-> mass type -> and then write by hand the weight value... does not satisfy me;
I would like to open the property tab and find the updated weight.
I tried the Czech to work on the formulas, but I couldn't do it and so I turn to you.

thanks:36_6_6:

in theory with the "measure inertia" tool calculates the mass automatically, then you just have to pounce on "measure preserve"... but it doesn't work very well to me: it doesn't take me into account the core mass of the material. . .
