topology edit node
Feature Description
The Topology Edit Node function is used to edit topology edges or object nodes. After enabling Topology Editing, you can move, delete, or add nodes while maintaining the connectivity of shared boundaries. If a node is shared by multiple layer objects, all referenced objects will be edited synchronously.
Access Point
- Edit Data tab -> Feature Editing group -> Topology editing dropdown menu -> Topology Edit Node.
Operation Steps
- Enable the editing state of relevant layers in the Layer Manager, then in the Edit Data tab -> Feature Editing group -> Topology editing dropdown menu, enable the Topology Edit Switches. After enabling, a topology map will be overlaid on the map.
- Select a topology edge, click the Topology Edit Node button, then all nodes on this topology edge will be displayed in an editable state, and you can perform the following operations on the nodes:
- Move Node: Select one or more nodes (support multiple selection by holding down the Shift or Ctrl key). Hold down the left mouse button to drag, and during the move, a rubber band preview will appear on the map showing the stretching effect. After dragging to the specified position, release the left mouse button to preview the moved effect, and then click the left mouse button again to complete the move operation.
- New Node: Click the left mouse button on the selected topology edge at the position where you want to add a node to add it.
- Delete Node: On the topology edge, select one or more nodes, and press the Delete key to delete the selected nodes.
- For topology nodes (ordinary nodes not on edges), only move operations are allowed. After selecting, directly hold down the left mouse button and drag.
- When editing nodes, if you do not want the shared objects connected to the selected topology edge or topology node to be modified, you can uncheck them in the Shared Object panel.
Notes:- Supports setting topology edit tolerance. Tolerance refers to the distance between object nodes; within this distance range, edges and nodes are considered to coincide and share the same position.
- By default, the system automatically calculates the minimum tolerance value based on the data, and in general, it is recommended to use the default value.
- If modification is needed, click the Tolerance Settings button, and you can manually modify it in the pop-up Topology Edit Tolerance dialog box; after modification, you can click the Reset button behind the input box to switch back to the default value.
