Function Description

In practice, we may need to merge objects. For example, if we want to merge the three provinces of Heilongjiang, Jilin and Liaoning into the Northeast Region on the national administrative division map, we can select the three face objects of the three provinces of Northeast China and use the merge operation to synthesize the Northeast Region.

Merging supports face or line object 。

There are a number of special cases that occur during the merge operation, which are described below.

1. The current layer is a face layer
   • If the faces participating in the Object Operation intersect at a point, these face objects are merged into a complex face object (as shown in the following figure, a complex face object with two sub-objects is generated).
   • If the faces participating in the Object Operation intersect on a line, the adjacent edges between the face objects disappear and merge into a single simple face object.
   • If the faces participating in the Object Operation intersect at a face, they are recombined into a simple face object.
   • If the faces participating in the Object Operation do not intersect and are not adjacent to each other, a complex face object will be generated after merging (as shown in the following figure, a complex face object with three sub-objects is generated).
2. Current layer is a compound layer
   • In the CAD layer, after the line object, curve object, Elliptic Arc and Arc participate in the operation, the type of the generated new object is line object; after the face object, Rectangle, circle object and oblique Ellipse participate in the operation, the type of the generated new object is face object.
3. Cross Layer Merge
   When merging
   • across layers, selected objects on other layers are merged with objects in the Current Editable Layer. After the operation, only the objects in the Current Editable Layer will change, and the objects in other layers will not change. When Multi-Layer Editing is turned on, you need to select the editable layer in which to merge the objects in the Merge window.

Function entrance

• Object Operation tab-> Object Editing group-> Merge.
• Map-> Context Menu-> Merge button.

Operating instructions

1. With the layer editable, select two or more objects.
2. On the Object Operation tab, in the Gallery control in the Object Editing group, click the Merge button to bring up the Merge dialog.
3. In the dialog box, set the objects you want to keep. Refer to the Property processing dialogs description for descriptions of the Object Merge Attribute Processing dialog and the parameters on the dialog.
4. Click the OK button to complete the merging of the objects.
