I am also having the same problem with the data shorcuts (Civil 3D 2013). I have tried the suggestions posted so far, but no luck. Any help would be appreciated.
I have the same problem using 2012 in that i would repeatedly get the error message requiring the dwg to be saved. I found that i couldnt create data shortcuts as my alignment was already linked to something in the dwg, In my case a profile & corridor. Once i deleted the corridor that it was linked to i could immediately create shortcuts.
It appears to have something to do with corridors and it's state when a save happens. Locking the layer the corridor is on appears to prevent the corridor from changing it's state based on the save action.
I'd experienced this error using Civil3D 2013. Previously my 'File Save' >> 'Save as:' Setting was set to AutoCAD 2010 (*.dwg). Whoever suggested problems with backwards compatibility was right, in my case. I changed this setting to AutoCAD 2013 (*.dwg) to match the year of the version I have and then I was able to create data shortcuts. I hate to forfeit compatibility for this though.
I'm still having this issue with Civil 3d 2014... I tried locking all layers... I do my corridors in a completly seperate drawing just to avoid this... But it's still happening. Any other ideas/fixes? Thanks.
Nevermind. I eventually got it to work. No corridors in my drawing but I entered this command SHORTCUTASSOCIATEDISABLE, saved, restarted cad, locked all layers, and then I could create shotcuts.
I was getting the same error, I would have to ask another coworker to open the design file and add it for me then close out. I ended up going to the options command and setting the save as default to 2013 instead of 2010 and I am able to add data shortcuts again.
I have had this happen to me in the past where I KNOW I have saved but still cannot create the datareferences.
what I found as a solution is to make sure that I associate current project to dwg and then save. After I do that I have no issues. I suspect the "....associatedisable" setvar mentioned earlier circumvents the need to associate project to dwg and therefore accomplishes a similar result. Although the dwg will not necessarilly associate with the project if disabled.
had the same problem today... based on the info i did the following with success. civil 3d 2013
select origin file for surface
right after the recovery process go to toolspace select surface and pick the data shortcut button from the ribbon
