The mode is designed for splitting areal objects into parts by the contours of reference objects. Areal, linear closed and unclosed objects can be used as reference objects. When splitting multipolygons, the split parts of objects are written as simple areal objects. By default, the metric of the reference objects is consistent with the editable ones: intersection points are inserted into the reference objects. If there is no need to edit the metric of reference objects, the matching of reference objects can be disabled.
