A roof slab is a flat roof that is similar to a slab except it is drawn above walls instead of below.


After you draw a roof slab, you can modify it as you would other entities using mod- ify entity commands.


For example, roof slabs can be easily moved and resized rela- tive to a wall. You can also use the Properties pane to change the thickness, style, etc. And when you select a roof slab, grips display allowing you to resize and reorient the roof slab in real-time.
