DEL/CHG allows you to delete or change the existing
attributes of entities that lie on a user-specified side 
of a defined plane.

Delete or change the existing attributes by choosing from
the following options:

DELETE - to delete entities that intersect a user-defined
plane.

CUR ATT (current attribute) - to change the attributes
(color, line type, line width, pen number, and level) of
entities that intersect, or lie on a selected side of a
user-defined plane, to those attributes currently in
effect.
