Civil 3D 2017 What’s New:  Not Backwards Compatible

June 15, 2016 By Leo Lavayen Leave a comment

On a recent support case, I came to realize that although Civil 3D 2017 uses the 2013 drawing format, the AEC objects (Points, Surfaces, Alignment, Profiles, Corridors, Pipes, Etc...) have been updated, causing them to not be recognized by the previous versions.

If someone using Civil 3D 2013-2016 was sent a drawing saved in Civil 3D 2017, they would get the message below when opening the drawing:

Also, when opening a 2017 drawing in a previous release, ALL objects will appear as large black boxes, with past commands and setting being disabled for this drawing.

Unfortunately, there is not much that can be done once a drawing file has been updated to the Civil 3D 2017.  Hopefully, you’ll have access to a backup of an earlier version of the drawing.  You could use the LandXML import and export features to share the intelligent model data between releases.
