This family was done in Revit 2017.
I am trying to create a family for a client.
I want to nest an array of rails in a host family. The array count will change depending on dimensions changing in the host family.
I tried using array formulas and couldn't get it to work well, so now I am trying the nested family approach.
I have created a Family Type parameter, but when I change it in the different types of the host family, nothing updates.
I am sure I am missing something simple, but can't get it to work at all.
any guidance would be appreciated.
