Function Entry

• Edit Data Tab -> Feature Editing Group -> General editing -> Partition -> Object Split

Operation Instructions

1. Set the layer containing the line or region objects to be split in the map to an editable state.
2. Select a line or region object in the editable layer as the object to be split. In the Edit Data tab, under the General editing dropdown menu, click the Object Split button in the Partition group to perform the object split operation.
3. At this point, move the mouse to the current map, and the mouse prompt will show: 'Please select the object to split.' Select a line object or region object as the splitting object, which means that based on the intersection of the two objects, the object to be split will be divided.

Notes:

• When multi-layer editing is enabled, users can simultaneously split lines or regions in multiple editable layers.
• When selecting the splitting object, only simple 2D line or region objects are supported. Otherwise, the output window will prompt: 'The selected object is not a simple 2D point, line, or region object. Please re-select.'
