Is it possible to control visibility of Void in a family?
Of course there is no 'visible' option in Void as above shown. Then we can think it can be controlled with using dimension like below.
Yes, if a family has a Void which can cut a host, it MUST cut a host.
But, It says just 'Cutting', not a 'Big Cutting'.
So, here is a solution. just make one more tiny, little, small cut in the family.
