Define Regions with Boundaries

2. In the Boundary Creation dialog box, in the Object Type list, select Region.
3. Click Pick Points.
4. Specify a point in your drawing inside each closed area that you want to define as a region and press Enter.

   This point is known as the internal point.

   You can make a new boundary set to limit the objects used to determine the boundary.
