AutoCAD Map 3D includes tools
to help you view and analyze raster-based 3D surfaces, such as Digital
Elevation Models (DEMs), ESRI Grid files, and Digital
Terrain Elevation Data (DTED).
For example, you can
create contour maps to help you analyze 3D terrain, use raster-based
theming to analyze elevation, slope, and aspect, drape map data
over surfaces and view the data in 3D, and more.
To add a raster-based
surface, you use Data Connect. For more information, see Bringing in GIS Features.
