within your drawing and define what kind of information you want to be
displayed in the annotation, as well as the layout of that information.
Annotation templates can include textual values, such as values from object
data or object properties such as a line weight, and graphics, such as images
and arrows.
NOTE For information about theming geospatial features, see Theming Features
(page 1168).

To apply annotation to a theme for a drawing layer
1 Select the annotation template you want to use.
2 Specify the insertion information, such as insertion point, scale, rotation,
linetype, and color.
Analyzing Raster-Based Surfaces
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
Overview of Adding Rasters and Surfaces (page 440).
