Object editing refers to common operations on geometries. For example, when creating a Boston map, we need to merge islands in the South China Sea into a complex object for unified operations. Similarly, when handling land updates, the local update functionality can be used to modify changed land boundaries. provides 49 commonly used editing functions, offering great convenience for data processing.

The Object Operations tab is a contextual ribbon tab providing feature drawing and editing functionalities bound to the map. This tab only appears when the active window in the application is a map window.

All geometric editing functions in the Feature Editing group require editable layers. To edit geometries in a layer, the layer must be set as editable in Layer Settings.

Basic Editing Operations: Introduces common map operations including copy, cut, paste, redo, undo, and delete.

Edit Node: Explains how to edit object nodes, including moving, deleting, and adding nodes.

Trim: Describes how to trim intersecting line objects (trim objects) at intersection points using a selected baseline.

Extend: Explains how to extend non-intersecting line objects to ensure they eventually intersect.
