Intersection of area objects

This mode serves for intersections search of area object. The work should be built as follows:

- choose sequentially two objects (and the first object should be area object and can have subobjects, and the second object can be area or linear closed object, but should be without subobjects);

- choose a type (sample) of created area or linear closed objects.

As a result it will be the created objects of the chosen type being intersections of initial objects.

Use One step undo mode to cancel creation of objects.
