Merging zone polygons

With this functionality you can merge the polygons of all or all active zones of a main zone or the polygons of all zones per main zone. For the main zones, the merged polygons of the allocated zones are used as new main zone polygon.

This functionality is particularly useful if the allocation of the zones to main zones has been modified, for example in the zone lists or when reading in a network file, and the main zone polygons need to be updated.

Note: Once the zone polygons have been merged, a main zone polygon can also have several faces if the polygons of the zone do not overlap beforehand.
