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

Choose YES from the displayed NO/YES menu to delete those
entities that intersect with the defined plane. Choose NO
to exclude them.

Select those entities desired for deletion using a
Selection Menu option.

Define the desired plane by choosing a Plane Definition
Menu option. An icon is displayed illustrating the
orientation of the new plane. Using a Position Menu 
option, indicate the side of the plane on which entities 
are to be kept.

The entities that lie on the other side of the plane are
deleted.

If you chose to delete entities that intersect the plane,
they are also created.

If you chose not to delete intersecting entities, only the
entities lying on the opposite side of the plane are
deleted. Those entities that intersect the plane remain.
