Feature

Feature Description

Accurately splits line objects through different splitting methods.

• The precise split function applies to line layers and CAD layers.
• Two splitting modes are available: Two-segment and Multi-segment. When selecting Two-segment, choose between percentage or distance splitting:
  • By Distance: Splits the line from the endpoint using a specified distance value. After splitting, the line object will be divided into two segments.
  • By Percentage: Splits the line from the endpoint using a percentage of total length. After splitting, the line object will be divided into two segments.

  When selecting Multi-segment, choose between segment count or interval splitting:

  • By Segment Count: Splits the line into equal-length segments based on specified quantity. Creates one or more new objects after splitting.
  • By Interval: Automatically calculates segment count using specified interval value. The remaining segment shorter than interval length will still be created. Example: For a 13-unit line with 5-unit interval, results in two 5-unit segments and one 3-unit segment.
• Closed Object Splitting: In SuperMap, closed line objects (e.g., circles, rectangles) are considered as objects with coincident start/end points (endpoints). Splitting closed objects will automatically split both endpoints simultaneously.
• Result Description: Original line object is deleted. Newly created line objects inherit non-system field attributes from original object, with system fields automatically assigned.

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

Steps

The following demonstrates multi-segment splitting as an example:

1. Select the line object to split in the current editable layer.
2. Click Precise Split in the Gallery control of Feature Editing group under Features tab.
3. In the Precise Split Settings dialog: View object information (ID and length), select splitting method (Two-segment or Multi-segment), and input parameter values.
4. Click OK to complete. Split objects are highlighted in red and blue on the map.
