Is this possible:

The equivalent of a Yes No parameter but where the value is yes - it would have a value. Im hoping it would apply to this scenario; a Windows position in a family is constrained by two dimensions (this isnt usually possible) but im hoping that there is some formula to select which dimension (length) parameter is the one you wish to use.

Any ideas?

I don't understand.  Just use a formula that uses the y/n parameter.

Im finding it hard to explain..

Suppose you had 2 seperate dimensions linked to 2 separate length parameters - both dimensions were linked to the same modelled object in different ways but you wanted to choose which dimension could control the object (one at a time) to avoid the overconstraining. An equivalent way of doing the above (as im not sure if its possible) is what im after.

thanks

Still not sure what you are asking.  You do know with if statements that it is either or and that you can nest if's like the formula below?

 

if(OH Braced, if(End Pilaster Bottom = 0', 0', OH Brace Height), 0')

I beleive I see what you are trying to accomplish, and the answer would be no. Why are you trying to do that? If you tell us what you are trying to end up with we might be able to help you come up with a better solution.

Ive now assumed it cant be done - but it was basically for a window that could do most things including having its dimensions being referenced from one side of the wall or the other side depending on your choice. obviously flipping the rfa would flip not just the dimensions but everything else in the family.

Thanks for the responses!
