Analyzing Raster-Based Surfaces
Concept Procedure

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.
