Split
Function Description
Split is used to break a line object at a specified position into new line objects.You can specify the break point by clicking with the mouse, and the snapping function can be enabled to assist precise positioning. It is suitable for scenarios where line features need to be split at specific positions, such as splitting line features like roads and pipelines at intersections, for segment management or attribute assignment.
This function only supports line objects in 2D, 3D line layers, and CAD layers. When using this function, the layer of object to be split must be in the Editable state.
Function Entry
- Edit Data tab -> Object Editing group -> Line editing -> Connect and break -> Split
Operating 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 split operation.
- The mouse prompt in the map shows: click to break. Click at the corresponding position of the object to be split to break it. The two newly generated line objects are temporarily displayed in different colors (red and blue) to distinguish them.
- When performing split features, if the selected break point is an intersection of multiple objects, the objects to be broken can be set. In the Select the object that you want to break dialog box, you can check the objects to break in the list. The selected objects will be highlighted in the map.
- After the operation is completed, the original line object is deleted, and multiple (number of splits + 1) line objects are newly generated. Their system fields are assigned by the system, and non-system fields retain the attribute values of the original line object.
Note:- Splitting parametric objects such as arcs, three-point arcs, and splines is not supported.
- In SuperMap, closed line objects are considered as objects where the start point and end point coincide. This coincident start and end point is called an endpoint. For closed line objects, such as circles and rectangles, after performing a single split operation, the system automatically splits the endpoints of the closed object simultaneously, thus generating two line objects.
