Suppress features using equations

Design Tables are probably best suited than equations to control suppression. You could probably put the equations in an Excel Design Table... Another approach would be through a macro, or even a macro feature... Could you provide more details on what you're trying to do ?

I have created lots of parts files for our model library that are based on design tables. In them I have used equations, suppressed/unsupressed features, etc. Check out the SW model library and look at the RC Sprocket for a good example.

has all the teeth created based on equations and input parameters, and all the hub/keyway/setscrew combinations available.
