System Variables
HPBOUND
Controls the object type created by HATCH and BOUNDARY.
HPBOUNDRETAIN
Controls whether boundary objects are created for new hatches and fills.
HPSEPARATE
Controls whether a single hatch object or separate hatch objects are created

Create a Blank Area to Cover Objects
Create a polygonal area, called a wipeout to mask underlying objects with the
current background color.
A wipeout object covers existing objects with a blank area to make room for
notes or to mask details. This area is defined by the wipeout frame, which you
can turn on for editing, and turn off for plotting.
Use the WIPEOUT command both for creating a wipeout object, and for
controlling whether wipeout frames are displayed or hidden in the drawing.
If a polyline is used to create a wipeout object, the polyline must be closed,
contain line segments only, and have zero width.
