To Create a Slab or a Roof Slab

Use this procedure to add a new slab or roof slab that has the properties specified in the slab or roof slab tool you select.

You add the slab or roof slab by specifying points to define its perimeter as follows:

• The first point determines the insertion point of the slab or roof slab and the start of the baseline. This point also locates the default pivot point of the slab or roof slab.
• The second point determines the endpoint of the baseline.
• Subsequent points establish the vertices of the perimeter.

1. Open the Design tool palette, and select the Slab tool or the Roof Slab tool.

   (You may have to scroll to display the desired tool.)

   Note: Alternatively, you can click Home tabBuild panelRoof Slab drop-downRoof Slab , or Home tab Build panel Roof Slab drop-down Slab .
2. Specify the start point of the slab or roof slab.
3. Specify a second point to define the first edge (baseline) of the slab.
4. Specify further points to finish defining the perimeter:

   If you want to…	Then…
   close the perimeter by drawing two edges that meet at a right angle	specify a point in the direction in which the perimeter is to close; then enter o (for Ortho). The edge is extended until it meets another edge perpendicular to the first edge.
   close the perimeter by adding an edge from the previous point to the start point of the baseline	enter c (for Close).

5. Press Enter.
