# Working with Slab Edges and Polygonal Slabs

There are two ways of forming slabs, either by using Polygonal Slab, or the Slab Edge.

**Slab Edge**

A **Slab Edge** is a single line shape with a default elevation of 1 ft.

Use the **Slab Edge** shape to create Slabs that have multiple sides.

Multiple Slab Edges connected together are commonly used for grade beams of varying thickness. Although most of the time a Slab Edge is used for a fully contained shape, their use is not limited to these situations. You can use a **Slab Edge** shape to define the side of single-sided wall formwork common to retaining walls.

Use the **Polygonal Slab** shape to create Slab Edges with multiple sides of the same length.

One of the main features for drawing Slab Edges is that the Formwork is drawn horizontally, or *laid down*, for Slab thicknesses (height) under 2 ft.

Since Slab Edges are fairly complex, there are many optional locations for you to place Ties. Refer to *[Working with Ties in Handset Designer](/wiki/spaces/ADH/pages/2238874100/Working+with+Ties+in+Handset+Designer)* for more detail on how to manually place Ties in a drawing.

You can configure the Slab elevations for a single edge or as a multi-sided Slab shape.
