Accurate Split

Function Description

Accurate split is used to precisely split a line object into multiple parts at a specified position. It is suitable for scenarios where line features such as roads and rivers need to be split by a specific length or ratio.

This function only supports line objects in 2D and 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 -> Accurate Split

Operation Instructions

  1. In the current editable layer, select the line object to be split.
  2. On the Edit Data tab, in the Line editing drop-down menu, click the Accurate Split button in the Connect and break group to pop up the Precise Break Settings dialog box.
  3. In the pop-up dialog box, you can browse object information, including object ID and object length, and also set the accurate split method. Two splitting methods are provided: Two-segment and Multi-segment. Select a splitting method based on your operation needs.
    • When Two-segment is selected, you can split by Percent or Distance:
      • By Distance: Use a specified distance value to accurately split the line from the endpoint. After splitting, the line object is divided into two segments.
      • By Percent: Use a percentage of the total length of the line object to accurately split the line from the endpoint. After splitting, the line object is divided into two segments.

    • When Multi-segment is selected, you can split by Classes or by Interval:

      • By Number of Segments: Split the line object by a specified number of segments, dividing the line object into equal-length segments. After splitting, the line object is divided into the specified number of segments, creating one or more new objects.
      • By Interval: Using a specified interval size, the application automatically calculates the number of segments to split. The last segment that is less than the interval value will also be split into a segment. For example, if the line object length is 13 and the interval size is set to 5, after splitting by interval, the line object is split into two segments of length 5 and one segment of length 3.
  4. After setting, click the OK button to complete the operation. The split objects are highlighted in red and blue on the map.
  5. After splitting, the original line object is deleted, and multiple new line objects are generated. The system fields of the new objects are assigned by the system, and the non-system field attributes retain the attributes of the original line object.
Notice:
  • Parametric objects such as arcs, three-point arcs, and spline curves are not supported for splitting.
  • Splitting closed objects. In SuperMap, closed line objects (e.g., circles, rectangles) are considered as objects where the start point and end point coincide. This coincident start and end point is called the endpoint. For closed line objects, after performing the split operation, the system will automatically split the endpoints of the closed object simultaneously.
