Break
Function Description
The Break function is used to split a line object at a specified location into new line objects. You can determine the breakpoint position by clicking with the mouse. The Snapping function can be enabled to assist with precise positioning. It is suitable for scenarios where line features need to be split at specific locations, such as splitting road, pipeline and other line features at intersections, to facilitate segmented management or attribute assignment.
This function only supports line objects in 2D/3D line layers and CAD layers. When using this function, the layer containing the object to be broken must be in the Editable state.
Function Entry
- Edit Data Tab -> Feature Editing Group -> Line editing -> Connect and break -> Split
Operation Instructions
- In the Edit Data tab, from the Line editing drop-down menu, click the Split button in the Connect and break group to perform the break operation.
- The mouse prompt on the map will show: click to break. Click once at the desired position on the object to break it. The two newly generated line objects will be temporarily displayed in different colors (red and blue) for distinction.
- When breaking features, if the selected breakpoint is an intersection of multiple objects, you can set the object to break by joining. In the Select the object that you want to break dialog box, you can check the target object in the list. The selected object will be
. - After the operation is completed, the original line object is deleted, and multiple (number of breaks + 1) new line objects are generated. Their system fields are assigned by the system, and non-system field attributes retain the non-system field attributes of the original line object.
Notes:- Breaking parametric objects, such as arcs, three-point arcs, and splines, is not supported.
- In SuperMap, a closed line object is considered an object whose start and end points coincide. This coincident start and end point is called an endpoint. For closed line objects, such as circles, rectangles, etc., performing a single break operation will automatically break the endpoint of the closed object simultaneously, resulting in two line objects.
