dwg will open in 2014 but not in 2013

[lmoore.217834]

I have a drawing with grading objects that was created in autocad civil 3d 2014 and will open fine with the version. It will not open in autocad civil 3d 2013, however and crashes every time. I've tried auditing, purging, and anything else I can think of. Any suggestions?

I don't believe that 2013 & 2014 are 'fully' backwards compatible... I recall that some AECC* Objects were not supported... If so, you might still need to use LandXML to export/import AECC* Objects.

AFAIK, the only things that are *supposed to be* known incompatible are Pressure Pipes with Data Shortcuts, and anything new to 2014 that was not in 2013 (such as Pressure Pipe Tables).
