Hello,
I want to control the nested family type with a formula (see blue underneath). If b1 is shorter than 6000mm, than the nested family (name nested family= glass, has very much types) is type G22, otherwise type G21.
But I get warning about glass. it says glass is not a valid parameter.
How can I to fix it?
The easiest way is to go to Revit forum an ask the Q there. You missed it AUTOCADARCHITECTURE forum
What kind of parameter is "W_S02"? Is it a Text parameter? If so, you need quotation marks, e.g. =if(b1<6000, "glass : G22", "glass : G21").
