Im working in a Titleblock family (but it would be same case for any family). I have this little situation:
I want to set a formula with a YES/NO parameter of visibility, involving other YES/NO parameters.
In other words, I want an element to be automatically visible only when others two (YES/NO) parameters are checked.
The formula I'm assigning to that parameter goes like this:
[SAMPLE 'YES/NO' PARAMETER]= AND(SAMPLE1=<true>, SAMPLE2=<true>)
Revit bumps be an error that goes: "Improper use of boolean expressions"
I want the output to be (<true>,on,yes) when the condition Im setting is satisfied, wether (<false>, off, no) when it isnt.
Any help?
Thanks in advance.
