Function Description

The Change Direction button provides the function to change the node order of selected lines or regions.

The Change Direction button is available only when there are lines or regions in the current selection and the selected object layer is editable.

Objects that support the node order reversal function include: 2D line objects, line3D, 2D region objects, region3D, and compound.

Function Entry

• Edit Data tab -> Feature Editing group -> General editing -> Trimming -> Change Direction

Operation Instructions

1. With the layer editable, select one or more lines or regions. You can hold down the Shift or Ctrl key to continuously select multiple line or region objects, or use drag-selection to select multiple lines or regions.
2. In the Edit Data tab's General editing drop-down menu, click the Change Direction button in the Trimming group to perform the operation of changing node order. Then, the direction of the selected object lines will change.

Notes:

• When multi-layer editing is enabled, users can select multiple lines or regions from multiple editable layers simultaneously to change their line directions.
• If the selected geometries include both line objects, region objects, and other geometries, and there are both editable and non-editable objects, then after performing the change direction operation, only the node directions of editable line and region type geometries will be changed.
