How to control a check box in a revit family with another check box

[Jrooker06]

How can I control a check box with a if/and formula in a revit family using another check box? 

Example: I would have (4) Yes/No check boxes in the family (Switch 1, Switch 2, Blue, Yellow). When I check the box Switch 1, I want it to check the Yellow box and uncheck the Blue box. When I check Switch 2, I want it to check the Blue box and uncheck the Yellow box.

Hi @Jrooker06. You needn't 2 switch checkboxes. Just write not(Blue) to Yellow formula.

 

Or use one switch checkbox.

 
Don't use if in formulas. Write only conditions. See example below.

Hi,
Is it possible to still use the Check1 & Check2 controls but enable the colour yes/no for selection (so the Check1 & Check2 are grey & the colours are selectable)
Thanks
