Modifying a 3D Mesh Layer

Elevation values in an area of a 3DML are modified using a modify mesh object. The surface of the 3DML is raised or lowered according to the elevation values of the modify mesh polygon's points. Different elevation behaviors allow replacing, cropping above or cropping below the original values of the terrain. The interior of the polygon can be flat or irregular in shape.

Note:    Modify mesh objects are supported for all mesh layers except imported OGC 3D Tiles.

To modify a 3D mesh layer:

1.     In the Project Tree, select the required layer.

2.     On the 3D Mesh Layer tab, in the General group, click Modify Mesh Layer. The Modify Terrain property sheet is displayed.

3.     In the 3D Window, left-click to place the modify mesh polygon’s waypoints, and right-click to complete.

4.     In the property sheet, set the modify mesh polygon’s properties. See “Modifying the Terrain” in the “Objects and Labels” chapter for more information.
