Equality Constraint in custom foundation family

[Joe_Hughes]

Hi,

I'm trying to apply equality constraints in a custom foundation family to ensure the triangular extrusion & void are located centrally as shown in Image 1 below.

However as shown in Image 2, when I increase the height of the segment the triangular extrusion & void are not centrally positioned.

Revit family attached.

Thanks in advance!

Hi,

The best way to make family's is to "create" your shape only with refplanes (bones)--> change values and see if the refplanes does wat you want. Then create your final family (flesh) and attach (lock) to the refplanes.

But here is your family adjusted.
