Draping Map Data Over 3D Surfaces
To drape 2D map data over a surface in your map, switch to a 3D view.
AutoCAD Map 3D automatically drapes 2D map data and displays everything
in 3D, creating a texture map.
For example, if you have a map with 2D raster satellite images, a 2D parcel
layer, and a 3D Digital Elevation Model (DEM), you can switch to 3D to drape
the satellite images and parcels over the DEM.

NOTE You cannot edit 2D data while it is draped in a 3D view. Switch back to
2D.
