When Edit the interior stairs and go to "Headroom Clearance" then click on the "Create Framed Hole" command for creating
the hole in the main floor joist to provide for stair and headroom clearance no hole gets cut in the floor ? I've tried it when
the active drawing and stairs are on the Main Floor and also when the active drawing and stairs are at the basement level.
I've even tried to use the command while in Floor System Mode and none of these do anything ? The stairs have not been
exploded. Is there some step I am missing or ....... ?
