Union of marked linear objects

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

- select type of created linear objects;

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

- specify, whether to check the 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 incorporated object. If values of the same semantics at objects are different then at the included control of semantics such objects are not united; if the control of semantics is disconnected, objects are united, and the incorporated object still 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.

If the Form multilines (polylines) option is enabled, then objects that do not touch will be added to the first found object as subobjects, taking into account the specified control of semantic characteristics for matching.

Use Undo mode to cancel creation of objects.
