I have an assembly which I am controlling with a global parameter file. The assembly is somewhat complicated in that there are about a dozen or more different add-ons that can be added, like different adaptor plates, handles, and extra parts, etc. Is there a way to use the global parameter file to selectively hide or show these extra parts? Or selectively suppress or activate them? This would be very helpful, because a different configuration for each add on would be an enormous amount of configurations.
