Creating 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/roof slab tool you select.
To specify your own settings when you add a slab or roof slab, see “
Creating a Slab/Roof Slab with User-Specified
Settings ” on page 1307.
You add the slab/roof slab by specifying points to define its perimeter as follows:
■
The first point determines the insertion point of the slab/roof slab and the start of the baseline. This point also
locates the default pivot point of the slab/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.)
2 Specify the start point of the slab/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:
Then… If you want to…
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 drawing two edges that meet at a
right angle
enter c (for Close). close the perimeter by adding an edge from the previous
point to the start point of the baseline
