Function Description

Accurately splits line objects through different break methods.

• The function of accurately splitting line objects is applicable to line layers and CAD layers.
• The break methods are divided into two-segment and multi-segment settings. When Two-segment is selected, you can choose to break by percentage or distance:
  • By distance: Accurately splits the line from the endpoint using the specified distance value. After breaking, the line object is divided into two segments.
  • By percentage: Accurately splits the line from the endpoint using the percentage of the total length of the line object. After breaking, the line object is divided into two segments.

  When Multi-segment is selected, you can choose to break by number of segments or by interval:

  • By number of segments: Breaks the line object by the number of segments, allowing users to split the line object into several segments of equal length according to the specified number. After breaking, the line object is divided into the specified number of segments, creating one or more new objects.
  • By interval: By using the specified interval size, the application automatically calculates the number of segments. The last segment that is less than the interval value will also be broken into a segment. For example, if the line object length is 13 and the interval size is set to 5, after breaking by interval, the line object is broken into two segments of length 5 and one segment of length 3.
• Breaking of closed objects. In SuperMap, closed line objects (e.g., circles, rectangles, etc.) are considered as objects where the start and end points coincide. This coincident start and end point is called an endpoint. For closed line objects, after performing the break operation, the system will automatically break the endpoints of the closed object simultaneously.
• Break result description. The original line object is deleted, and multiple new line objects are generated. Their system fields are assigned by the system, and non-system field properties retain those of the original line object's non-system fields.

Operation Instructions

The following will take multi-segment break as an example to explain the break operation in detail.

1. In the current editable layer, select the line objects to be split.
2. In the Gallery control of the Features tab's Feature Editing group, click the Accurate Split button to perform the accurate split operation.
3. In the popped-up Precise Break Settings dialog, you can view object information, including object ID and object length, and set the accurate split method. Two methods are provided: Two-segment and Multi-segment. Select a break method according to operational needs, and enter the break parameter values in the parameters.
4. Click the OK button to complete the operation. The broken objects are highlighted in red and blue on the map.
