Feature Editing : Edit
 

Edit

 

A feature is edited using the Edit Feature command. When this command is active, area and line features are shown with yellow squares representing the vertices and nodes.

A node is the point where two edges meet. A node is represented as a large yellow square.

Point features have a single yellow square, representing the actual position of the point.

Editing of a line or area typically involves changing the shape of the feature by adding, moving, or otherwise modifying vertices.

When a vertex is selected, it turns red. You can select single or multiple vertices.

When you edit a feature, it is locked to prevent other users from editing it at the same time. The feature remains locked until you save it, reload the workspace, or end the current session.

If you try to edit a feature that is locked by another user, a message informs you that the feature is not available for editing. You will have to wait until the feature is available.

Some features share some of their geometry with other features. To apply changes to all features that share the geometry, the Edit All Features command must be active.

If editing would result in invalid geometry or if the changes could not be shared unambiguously, the shared features might not be edited.

The following editing can be performed:

Move a Point

Move a Vertex

Add a Vertex to an Edge

Delete a Vertex

Split Edges

Merge Edges

Smooth Line

Filter Selected Vertices

Redigitize Edges

Trim/Extend an Edge

You can also use the Coordinates window to move vertices and point features. See Coordinates Window.
