That was someone else's comment ( tucker_arch ) but I think what they are trying to say is :
If you set a Yes/No parameter to have a formula of 1=0, Revit will return <False> or an unchecked Yes/No parameter.
The formula doesn't have to be 1=0, it can be any false statement... 10<230, (1*2)=10000000000, I can dance! (well maybe not the last.)
Making a true statement will result in a "Checked" box. 1<2, 1=1, etc etc.
Now just paste the true formula into the formula cell of the types you want to HAVE a sill and the false formula into the types you don't.
I wish tucker_arch had an account or contact info so I could have asked what they truly meant. If that's you (or you know tucker_arch) let me know and I'll add your comments here.

Hi Erik,
I saw your tip on the CAD Shack blog about formulas in Revit. Here's
the link to the blog:
http://cadshack.blogspot.ie/2012/01/revit-family-formula-examples-and.html
I have a question for you that you might be able to solve. I am making
a new window and I want to have the option to turn the visibility of
the sill on or off, depending on the type of window I use. I have
nested the sill into the family, and I have assigned a visibility
parameter to the sill, but how to I assign a formula to be able to
turn it on and off? You wrote on the CAD Shack blog about 1=0 and 1=1,
however I'm lost as to how you enter these into the formula column?!
I would really appreciate you advice on this.
