Union of marked area objects

The given mode is intended for union of area objects marked by means of Search modes or by Grouping mode. Thus only the area and closed linear objects located in one map sheet are handling. The following operations order is recommended for work:

- select type of created area objects;

- indicate whether it is necessary to delete the initial objects after creation of new objects;

- indicate, whether it is necessary to check coincidence of semantics values;

- click Ok button.

It is possible to interrupt the mode execution by Exit button. Recreated objects are the outcome of operation, thus the touched each other objects will be united into one. If semantics at united objects coincides, it remains and at the united object. If values of same semantics at objects are different, then at the included check of semantics such objects are not united; if the check of semantics is switched-off, objects are united, and the united object will has value of semantics of the first object. If one of joinable objects has any semantics, and another one hasn't the same one, missing semantics is added to united object.

Use Undo mode to cancel creation of objects.
