Align Edges
Feature Description
The Align Edges tool is used to snap edges that share two topology nodes, allowing for quick gap filling between two objects to achieve seamless boundary alignment.
Function Entrances
- Edit Data Tab -> Feature Editing Group -> Topology Editing Drop-down Menu -> Align Edges.
Operating Steps
- Enable the editing status of the relevant layer in the Layer Manager, then open Topology Edit Switches in the Edit Data Tab -> Feature Editing Group -> Topology Editing drop-down menu. After enabling, a topology graph will be overlaid on the map.
- In the Edit Data Tab -> Feature Editing Group -> Topology Editing drop-down menu, click the Align Edges button.
- Move the mouse over the map; a prompt will appear: "Solid lines indicate edges to be modified." Click the solid line part, and that edge will align to the dashed edge.
- Hover the mouse over the edge to be edited; the edge to be edited will be highlighted with a solid line.
- Click the edge highlighted as a solid line, and it will automatically align to the edge highlighted with a dashed line.

Notes:- Supports setting the topology edit tolerance. The tolerance refers to the distance between object nodes, within which edges and nodes are considered coincident and share the same location.
- By default, the system automatically calculates the minimum tolerance based on the data. Generally, it is recommended to use the default value.
- If modification is needed, click the Tolerance Settings button. You can manually modify it in the popped-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.
