To Work With Regions

Regions are 2D enclosed areas with physical properties such as centroids or centers of mass.

Define Regions

1. Click Draw menu > Region.
2. Select objects to create the region.

   These objects must each form an enclosed area, such as a circle or a closed polyline.

3. Press Enter.

   A message at the Command prompt indicates how many loops were detected and how many regions were created.

Define Regions with Boundaries

1. Click Draw menu > Boundary.
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.

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