Drawing Sharing Command Reference in the Civil 3d help file.  It lists all the commands such as ExportToAutoCAD2010 and each command’s description.

If you need a specific file version and you are running just AutoCAD there is -AECEXPORTTOAUTOCAD2000 or -AECECPORTTOAUTOCAD2004 or eTransmit with the option to explode AEC objects will give you the same results.

Using -PURGE (the command line version of PURGE) and choosing RegApps option will also clean out unnecessary Registered Applications that may cause stability problems with your drawing.
