DIVIDE allows you to break a selected entity (excluding
circles) into three separate entities defined by two
intersecting entities.

Select the portion of the break entity that will take on 
the new attribute settings.

Select the first of the two intersecting entities near 
the intersection point of the entity to be broken.

Select the second of the two entities in the same manner,
near the intersection point of the entity to be broken. 
The reference entity can be selected again if it 
intersects the entity to be broken at a different point.

The entity to be broken is redrawn as three separate
entities. The first of the three entities is on the 
outside of the first intersecting entity and keeps the 
original attribute settings. The second entity lies 
between the two intersecting entities and takes on the 
current attribute settings. The third entity is on the 
outside of the second intersecting entity, and like the 
first one, keeps the original attribute settings.
