Imagine these scenarios:

1) You have two different nested families in your family. You only want one or the other displayed. You create a single YN parameter called OptA.

Now the first nested family has its visibility set to the value of OptA (just like we would do it now). The second nested family would have its visibility set to Use Formula and the assigned formula would be Not(OptA).

2) Your family has THREE nested families. One or both of the first two nested families can be seen at a time but if neither are shown, the third one should be shown.

So the first fam would have its visibility set to Opt1, the second would be set to Opt2. The third would be set to Use Formula which would be And(not(Opt1),not(Opt2)). So now if neither one of the first two is shown, the third will be shown.
