Users who do not have AutoCAD Civil 3D but who have an AutoCAD-based product can install the Object Enabler and view your drawing exactly as you created it.
The Object Enabler is available on the AutoCAD Civil 3D installation CD and on the Autodesk web site at www.autodesk.com/aecobjenabler.
After a user installs the Object Enabler, the user can open the drawing and view, plot, manipulate, and copy AutoCAD Civil 3D objects using standard AutoCAD commands. AutoCAD Civil 3D objects are maintained as intelligent objects, and the drawing can be re-used in AutoCAD Civil 3D.
