How to move these automatically?

[cba2KUJ4]

Hey People,

I have exhaust hoods family here.

When I change the length for it, I want the two extraction holes to move along, so that they are automatically 1/4 of the total length.

Can somebody help me with that?

Hi,

Add a parameter in the dimension that you want the 1/4 of length.

Then in Family Types at this parameter add a Formula like =0,25*L (I notice that you name "L" the length)

There is no need to add any parameter.
