Feature Description

The Split function divides line objects into new segments.

• This feature allows breaking line objects at any clicked position.
• Applicable layers include line layers or CAD layers containing line objects. The target layer must be editable.
• During splitting operations, the snapping function can be activated for precise positioning, particularly useful when breaking at line intersections.
• When selecting intersection points of multiple objects, the Select the object that you want to break dialog appears, enabling object selection with highlighted visualization in the map.
• Special considerations for closed objects:

  In SuperMap, closed line objects are considered as features with coincident start and end points, collectively referred to as endpoints.

  For closed line objects (e.g., circles, rectangles), a single split operation will automatically break both endpoints, generating two separate line objects.

• After splitting, newly created line objects are temporarily displayed in distinct colors for differentiation.

Feature Entry

• Features Tab->Feature Editing Group Dropdown->Split.

Steps

1. Click the Split button in the Feature Editing group under the Features tab to initiate the operation.
2. Map cursor prompt: "Click to break". Click the desired position on the target object to split it. New segments temporarily display in red and blue.

   Post-operation, the original object is deleted and replaced with (number of splits +1) new line objects. System fields are auto-populated, while non-system fields retain original attributes.

3. When splitting at multi-object intersections, select target objects through the Select the object that you want to break dialog. Checked objects highlight in the map.

Note:

The split function is unavailable for parametric objects (e.g., arcs, three-point arcs, splines). Parametric objects exist in CAD datasets.
