Family table need to be regenerate twice so I need a workaround

[asikatz]

Hello,
I have a problem with family tables regeneration, to be more specific:

I'm modeling a family of components and I know every component's mass. I need to extract the component density.
The generic model includes this lines in the relationship section:

mp_density=catalog_mass/mp_volume("")

catalog_mass is a parameter that contains (as the name implies) the components mass.

The thing is when I open an instance I need to regenerate the component twice in order to get the mass calculation right.
I tried using feature analysis and then replace mp_volume("") with volume:fid_analysis1 but I still need to regenerate twice.

This thread thread554-24699 implies that I can workaround this problem but I don't know how.
Any help will be great.
THANKS.
Asi.

Sorry for my English.

Asi,

First of all, congratulation you were searching on this forum to find a solution to your problem.

The diference between your case and Oxana's case is that you will add a new relation to extract the density function of your density_catalog variable.

Oxana only wanted to extract the mass from the part after a single regeneration.

I'm affraid there is no workaround to have the right mass after a single regeneration.

But... if your parts will not change in time, (because if they change, you'll need to modify also the catalog_mass) then why not to assign the right density to your parts? In this way, following the theard you mentioned you can use that method.
