Hi! I am coming from the Vectorworks environment, and there is something there that I miss in Revit (not many things though)
In VW there are Storeys, and they are defined with a height relative to the 0.00 level of the model/project.
Than each storey has "reference levels" that are defined with a relative height to the corresponding storey.
That makes it incredibly easy to define families in relation to these relative heights, as the heights can have a coherent name across storeys...
You place a wall Type-A in the ground level and it will bind itself to the defined heights.
You place a Type-A wall in the 1st level and it will adapt itself to the corresponding heights without any need for intervention.
I guess we have "similar" processes, but not completely automated like in vectorworks, right?
Thanks in advance and cheers!
