Feature

Feature Description

Splits line or region features using a temporary drawn split line.

The Line Split button becomes available only when the current map contains editable layers with one or more selected objects.

When multi-layer editing is enabled, the drawn temporary split line will divide all selected line/region features across editable layers that it intersects. These objects may reside in different layers.
