Cutting a Volume out of a slab

[lily.beyer]

I'm trying to cut a depression into a floor slab in Revit 2012. I've tried to make a void form, on the grounds that I'm trying to make a void in my slab, but it doesn't show up unless I'm cutting a void in a mass. I also tried to use the shaft command, without extending it completely through the floor, but as soon as it reaches the floor it cuts completely through.

Is there a way to cut a volume out of a floor slab without cutting completely through the slab?

Thanks.

Try this, it works for rectangular openings.  Just create different family types for depth of depression.

How about "Opening--Shaft" with defined constraints?

This may not be the best solution, but if I have a 6" slab and need a 2" depression, I cut a hole through the slab. Then I place a 4" slab in the void 2" down then join the 2 slabs. This gives me the appearance I need and the correct volume of concrete.

This worked perfect! Exactly what I have been looking for. And I was able to modify it so the depth was adjustable. Thanks jbrazier!!

I beleive a shaft opening will always cut all the way through a floor/slap that it touches- you can't partially cut with a shaft opening.
