NOTE Foundation slabs are added below the level in which they are drawn. Therefore, if you add a
foundation slab in Level 1, it is added below Level 1 and will not be visible in the Level 1 plan view.
To see the foundation slab in a plan view, create a new level below Level 1, for example, Foundation
Level. When you create a new level below Level 1, you will also be able to see the foundation slab as
an underlay (displayed in halftone) in Level 1.
