BREAK allows you to break selected entities at their
intersections with a user-defined plane.

Select the desired entities to break, using a Selection
Menu option.

Define the desired plane by choosing a method from the
Plane Definition Menu.

An icon is displayed that illustrates the current position
and orientation of the new plane.

Using an option, indicate a side of the plane on which the
entities stay the same. The system identifies the
intersections of the selected entities with the defined
plane. If intersections are found, the entity is broken to
the defined plane.

The entities on the selected side of the plane keep their
original attributes, while the entities on the other side
take on any new assignments.
