AHU with optional for rectangular or round supply connection?

[christo4robin]

I'm new to using MEP. Constructing an AHU family and wondering if it is possible to have a supply connection that can be round or rectangular?

I don't see a way to drive this switch with a paramater and the only solution I can see is to have two connections one on top of another, and then allow the user to tab through to the one they want. Is that correct?

TIA.

There isn't any good way to do this.

You can't switch between the two-
You can't put both in the family and turn one off-

I think you are stuck with 2 families.
