Adding Surface Point Data from AutoCAD Drawing Objects
 
 
 
Bottom of the Page

Use AutoCAD objects such as 3D lines to add surface point data to the surface definition.

The selected AutoCAD objects are interpreted based on their points, and specific point data is created for each object type that you add to the surface definition.

For several object types, you can specify whether to maintain the object edges when adding the object points to AutoCAD Civil 3D.

Note

Drawing objects added to the surface are added as point data. After the point data has been added to the surface there is no relationship between the surface and the original drawing objects.

You can select the following AutoCAD drawing objects to add points to a surface definition:
