Headroom as a boolean object?

[Kamelite]

Is it possible to use the headroom-figure to make a hole in a slab?

You could try it yourself: use the Solid Element Operations Palette and use the stair as Operator and the slab as Target, then you will see if it works. I I cannot try it myself, because I'm not at my computer at the moment.

I already did, but as i select the overhead-figure, I also select the stair. And doing a boolean operation just removes the footprint of the stair.

Just wondered if there were any clever tricks to accomplish the task.

Thanks anyway!
