Revit Family Parameter List

[Anonymous]

Is there a way to turn off multiple parameters within a formula? Example, "A" if turned on then turn off "X", "Y", and "Z"? Right now I have a parameter as such: Parameter "A" : not(X) . Which turns off the parameter I want but I want to turn off more than one parameter if that one is turned off. In other words I just want to have one option/parameter visible at any given time. I could also do a drop down setting but not sure how to use that feature so if that is a better way to do this pointing me to some tutorials for that would be appreciated.

What parameter are you using for that?

[Alfredo_Medina]

The "See item" parameter is an integer. Sometimes I call it "See this".

There are a number of ways to approach this depending on the circumstances.  For instance, you can approach through Formulas using several Conditional Statements in one that evaluate multiple Parameters using logical "AND" and "OR".

If you want A to control X, Y, Z then the formula should be assigned to X, Y, Z, not A.

X=not(A)

Y=not(A)

Z=not(A)

Or perhaps, your example is not reflecting the real scenario that you are after because no sane person would need 3 different yes/no parameters that always have the same value.
