Working with Keep-in/Keep-out Areas
A Keep-in area is a polygon that you set so that when objects are moved
outside of it, a DRC error is generated. Conversely, a Keep-out area
generates a DRC error when objects are moved into it.

The Keep-in/Keep-out properties dialog box lets you place a polygon that
will act as either a Keep-in or a Keep-out area. By default, a Keep-out is
placed.
Complete the following steps to add a restricted area:
1. Choose Place»Keep-in/Keep-out Area.
2. Left-click all points that are to define the polygon, ending with the
starting point.
