Editing objects is a common operation for Geometry. For example, when we draw Boston Map, we need to merge the South China Sea Islands into a complex object to facilitate unified operation. For another example, when dealing with land change, you can use the Local Update function to update the changed land boundary. The product provides up to 49 common editing functions, which brings great convenience to data processing.

The Object Operation tab is a contextual tab, which provides the function of Object Drawing and editing on the map, and is bound to the Map. This tab appears on the ribbon only when the currently active window in Application is Map.

The Geometry Object Editing functions provided by the Object Editing group are performed while the layer is editable, so to edit a Geometry in a layer, the Layer Settings must be editable.

Basic editing operations : introduces several operations commonly used in maps, such as copy, cut, paste, redo, undo, delete, etc.

Edit Node : describes how to edit the node of an object, including move, delete, Add Node, etc.

Trim : describes how to trim a selected line object (baseline) and another line object (trim object) that intersects with it at the intersection.

Extend : Describes how to extend disjoint line objects to ensure that they eventually intersect.

Break : describes how to break a line object into a new object at the mouse click position.

Accurate Split : describes how to break a line object at a specified position. Provides methods to Accurately Split lines by distance, by percentage, by number of segments, and by spacing.

Change Direction : Describes how to change the direction of a line object.

Fillet : describes how to extend or trim the adjacent endpoints of two line segments and finally connect them to form a fillet.

Chamfer : describes how to extend or trim the adjacent endpoints of two line segments, and finally connect them to form a chamfer.

Central Point Adjustment : It introduces how to perform adjustment calculation on the nodes on the adjacent line objects within the adjustment range to generate a new node and connect the adjacent lines.

Explode : Describes how to decompose a line object into a simple object containing only 2 endpoints.

End-to-end Connection Line : Describes how to connect two or more simple line objects into one line object.

Curve Resampling : describes how to remove some nodes while keeping the line shape as much as possible.

Curve Smoothing : describes how to smooth a line so that the line object becomes a continuous smooth object.

Specify Offset : Describes how to create a new object whose shape is parallel to the source object with the source object as a reference.

Positioning Copy : Describes how to copy a selected object to a specified location.

Mirror : Describes how to create a mirror object that is symmetrical to the selected object.

Rotate : Describes how to rotate an object by a certain angle.

Line Split : Describes how to split a line or face object with a temporary split line drawn.

Polygon Split : Describes how to split a face object by a drawn temporary split face.

Object Split : Describes how to split a line or face object by selecting a line or face object.

Local Update : Introduction to updating a part of the shape of a line object or a face object with a drawn polyline.

Style Brush : Describes how to assign an object's style to another object.

Attributes brush : describes how to assign the Attributes of an object to other objects.

Merge : Two or more objects are merged into a new object through the merge operation.

Intersection : Obtain the common part of two or more objects through the intersection operation.

Combination : Combine any objects (of the same type or different types) into a Compound through combination operation.

Split : Split one or more complex objects or Compounds through the split operation.

Protective Decomposition : Decompose a complex face object with multiple layers of nested island holes into a face object with only one layer of nested island holes through Protective Decomposition operation.

Exclusive-or : The removal of the common part of two or more objects and the Compose as one object of the remaining part by an exclusive-or operation.

Erase : The part overlapping with the erase object in the Target is deleted through the erase operation.

Donut Polygon : Process (delete or retain) two or more face objects with containment relationship in the overlapping area, and finally form a Donut Polygon.

Line to Point : Describes how to Convert to Point a selected line object.

Line to Region : Describes how to convert selected line objects into face objects.

Region to Line : Describes how to Convert to Line a selected face object.
