Exporting to Google Earth from Civil 3D 2007

This procedure was from a recent Autodesk Civil 3D 2007 webcast...

Export Google Earth
1. Assign a coordinate system to your drawing
a. It helps to use the same coordinate system as the DEM or Surface you are using is in.
2. Create a new Surface definition
3. Add a DEM file to the surface (these work best because they are closest to the surface displayed in Google Earth)
4. Make sure to transform the DEM to the coordinates set in the drawing
5. Design your alignment, profile and assembly
6. Create your Corridor
7. Create a top Surface for the corridor (the command is hard coded to just use the first surface in the list, so don’t bother creating more then one)
8. Run the ExportGoogleEarth command (can also use AeccExportGoogleEarth if calling from a routine or button)
9. Select the corridor
10. Name and save the file

Viewing in Google Earth
1. Open GE
2. From the File menu, select Open
3. Browse to the kml file created above
