To add an irregularly shaped slab to the current plan, use the following steps.

1. In a plan workspace, select Slab  >  Create Irregular.
2. Click an initial corner for the slab.
3. Click another corner in either a clockwise or counterclockwise progression from the previous corner. The Point Select dialog opens.
   
   Tip: The Point Selection dialog will not open if the program detects you have indicated an existing slab corner.
4. (Optional) Specify an X Offset and Y Offset value (relative to the point highlighted in a red circle), Distance, and Angle value to place the point at another location.
5. Click OK.
6. Repeat steps 3 through 5 to select each additional vertex point on the slab.
7. Right-click to stop adding corners. The Slab Details (Irregular) dialog opens.
   
8. Specify the slab details:
   1. Type label, material, geometry, and load parameters.
   2. Specify the direction the slab spans: Two Way, One Way, or Distribute on Selected Edges.
      Tip: The resulting dimensions determine the recommended default direction. If one or more slab spanning directions is determined to be unsuitable based on the dimensions, it is disabled.
      Tip: Cantilevered slabs can be specified using the Distribute on Selected Edges option and clicking a single, supporting edge.
9. Click OK. The slab is drawn in the Plan | Slab page graphical view.
10. Repeat Steps 2 through 9 to continue drawing irregularly shaped slabs.
