Copying of object fragment

 This mode is applied to the spatial topological join of the objects having common border (if this join was not made at the creation of these objects on any causes).

For the objects join it is necessary to execute following operations:

- select object of which one the contour fragment should be patterned into other object;

- select source object fragment which one should be copied;

- select edited object;

- select edited object fragment  to be replaced.

Selection of fragments is made by three points.

As edited object and object - source must be only line or polygon objects.
