Drawing Subpolygons
While in polygon mode, you can define either one polygon or a series
of subpolygons. Like a polygon, a subpolygon is a closed sequence
of connected line segments. For example, the block letter C is one
complete polygon. However, the block letter D is actually two
subpolygons: the outline and the ‘hole.’
Figure 21-7 Drawing Subpolygons
To create one polygon, for example, the letter C, move the pen to the
starting location for the polygon, then use the Polygon Mode (PM)
command to enter polygon mode. Define the shape of the C using
the appropriate commands and coordinates, then exit polygon mode.
Now draw the polygon using either the Edge Polygon (EP) or Fill
Polygon (FP) command.
