So, I searched and searched, and I know there is at least one thread about this on the forums, but I just couldn't find it. Sorry!
Anyway, I'm trying to make a sink that will cut into a counter-top family we've already made. We build these vanities the same regardless of the purpose, and just mount sinks to them if we need them. Obviously, the ideal way to do this is to make a face-hosted sink family with a void to cut the counter top. However, I can't make it work for the life of me. It can cut walls, floors, etc... but it won't cut a counter top. Even more annoying, it will host in the counter top, but won't cut it. The counter is a simple casework family.
What in the world am I missing?
