AutoCAD Civil 3D

[#1]

I just had my drawing crash and Autocad asked me if I wanted to save the drawing and I said yes.
When I go back to Autocad and try to revocer the saved drawing I get the following message "Unable to recover drawing file".
Even when I try to use the recover command do I get the message.

I am using Civil 3D Land Desktop Companion 2008 SP2
It does not mattter which version of Autocad 2008 (LDD, 3D, Enabled) I use the file will not open.

You have 2 choices...

1. Open a different drawing...select file open...on the open dialog box...select your corrupt dwg...hit the arrow next to open and do a partial open...if it opens try to recover, and audit the dwg and save it again. The partial open rids the corrupt entities...

2. open a blank dwg, ddinsert command, insert at 0,0, and explode it, save as your working drawing,

Always back up your file prior to suggestions*

I had thought of those option already and the partial open option is not available for that drawing and when I do an insert I get the following message
"114093_Design_recover.dwg was created by an incompatible version of Autocad".
It looks strange because I am opening the drawing in the same Autocad version as it was saved in when it crashed, I even tried to open it in Autocad 2005 and I still get the same message.

You could try to open the file in ACADmap and query the layers in the drawing and save to a new drawing. This procedure does not work for paperspace entities, just model space.

I have had this happen a couple times also. Check the actual file size of the recover dwg file. Normally if it's small (5-6kb) you're out of luck and AutoCAD couldn't save enough.

The other trick that we found which worked for our Civil 3D 2008 files, is to open it in 2010. It works every time we've tried it, but then you can only open the file in 2010.

For working out given trouble you may use present program. dwg recovery has many facilities which allowing recover crashed or lost dwg files after power failures, viruses.

I never answer Yes because I've never seen a usable file saved when I did. You'll have to go to a .BAK file or an SV$ file if one still exists.
