yes/no parameter

[Anonymous]

I have 3 yes/no parameters in the file that i would like to have when 1 parameter is checked the other 2 are no longer checked. This is similar to the not formula but with more than 2 check boxes. Is there anyway to make this work? Any help would be appreciated.

Thanks

... just bouncing ideas, but would an IF parameter work on the other parameter? You may find it locks you out of one combination though... i have done this before the same way, but it limited me to 2 options instead of 3...

Also Family Types make it easy to preset them and allows users to choose the correct version based on the types you create. That's how Revit means for us to work unless these choices are subservient to primary types you've already got defined and it means doubling or tripling the number of types required.
