unable to associate nested parameters (tutorial not match my program)

Hello,

I made a child family rfa 1 (built with all parameter formula eg X) then nest to a parent family rfa 2,

then I want to associate a parameter of rfa2 (say Y=2X) with the child nest rfa 1 (X).

In all tutorial video I searched, there are a botton beside the parameter for such association, but,

this association botton not exist in my program (RVT 2021), 

whatever I tried "family tpye" or "shared parameter", or tried "type" or "instance)---the formula in child rfa 1 just unable to be transfered to parent rfa2 -- so how can I control Y of parent to follow X of child (Y=2X)?

The buttons are found in the  child not the parent. You associate from the child to the parent (children are the dependent)

 

To do what you want 

  1. Create a Paramter in the Parent also call X
  2. Set a formula for X Parent = 0.5*Y
  3. Select child >> edit type >> associate to X in Parent

hello Mr RDAOU,

 

so that means the nest shall be from parent down to children (reverse from my current process), 

OK I try, (as I am developing a full parametric wood structure system to control the cutting machine production line)

Many thanks Mr RDAOU

Yes...The parameter values are passed on from the Host/Parent to the Nest/Child.
