AutoCAD Civil 3D 2012 Drawing Compatibility

The DWG file format changes from time to time, as newer technology or improvements are incorporated. In general, newer product versions can always open all older DWG file format versions. However, when a new DWG file format is introduced, prior versions will not be able to open it. For example, drawings in 2010 DWG format (which is a new file format) cannot be opened in AutoCAD Civil 3D 2009.
