void in family not cutting

[Bryan Thatcher]

I have a face based family with a void that i cannot get to cut it's host. I have also tried a wall based family that I cannot get to cut. How can I get a void to cut it's host, thanks.

In the family, you have to set the void to cut the host.

Yea, thanks, tried everything.

Is the face or wall based family nested ?
