You can extract AutoCAD entities from an Autodesk Civil 3D surface.
Extracting individual components from a surface enables you to manipulate these components without exploding the surface object. The surface data available to extract is based on the display properties of the selected surface.
The following table lists the extracted objects for each type of surface components.
Surface component ... | Is extracted as ... |
---|---|
Points (2D and 3D) | Point objects |
Triangles (2D and 3D) | 3D face objects |
Border (2D) |
|
Border (3D) |
|
Major Contour (2D and 3D) | LWPOLYLINE object |
Minor Contour (2D and 3D) | LWPOLYLINE object |
User Contours (2D and 3D) | LWPOLYLINE object |
Gridded (2D and 3D) |
|
Directions (2D and 3D) | The type of object depends on the surface style settings. See To Create a Surface Style. |
Elevations (2D and 3D) | |
Slopes (2D and 3D) | |
Slope Arrows (2D and 3D) | |
Watersheds (2D and 3D) |
