I'm fairly new to nested families and I'm trying to use a sink family provided by Kohler in a cabinet family I've created. The family is a face based family that comes with void form but for some reason it will not subtract from my countertop/cabinet volume. Can anyone give me any possible tips. I've read some things about needing to match the category of the various elements involved. The cabinet family is currently a casework category. Any help is greatly appreciated.
