I am making a furniture piece for a project that I am doing for my office and The furniture piece has brackets to keep the countertop up. The furniture system changes in length and depending on the length, two of the brackets may or may not be there. I was wondering how I could set a tolerance for the Yes/No Parameter so they go away when the length is below a certain length? I tried putting it in, but they didn't turn off. Anyone know?

Create a "Length" Parameter for the overall length.

In the Family Types Dialog Box, in the formula for your Yes/No Parameter, create an equation that reads: Length > X'-X" ...This will turn the parameter ON if it is greater than that length. Make sure you have the Visibily for each bracket set to the Yes/No Parameter.
