Add to object («U»)

When creating a linear object, it is possible to add the created object to the contour of an existing linear object. After pressing the «U» key or selecting the appropriate auxiliary mode, the operator is asked to select the object on the map to which the created contour will be added. The selection can be made only among linear objects. The type (code) of the selected object may not coincide with the type of created one. After adding, the type of an existing object, as well as the direction of digitization and the set of semantic characteristics, do not change. Digitized section is added to the nearest end of the selected object. If the created or existing objects consist of components (subobjects), the contour (s) of the created object will be added into the selected existing one as subobjects.
