Specify the Geographic Location of a Drawing
You can specify the geographic location, orientation, and elevation of the
objects in a drawing.
This information is useful for sun studies, environment analysis, exporting
to AutoCAD Map 3D, and working with Google Earth.
Geographic location information can be specified in one of the following
ways:
Enter the latitude, longitude, and altitude manually
Import a KML or KMZ file with the geographic information
Import a location from Google Earth
When you specify the geographic location of a drawing, a geographic marker
is created. The geographic marker is a visual representation of the location
information, and is created at a specified point on the drawing.
