Export to Autocad - missing objects

[Anonymous]

Hi, I'm working on a Civil3d file from which I have already successfully exported to Autocad DWG several times during the last weeks.

After a few changes and adjustments in my corridors, the drawing is not exporting correctly, as I can't find my geometries in the DWG file. No corridors, no section views, no profile views, no surfaces. I only find the lines and polylines that I have manually drawn into the file.

Before the 1st export I hadn't changed anything in the export settings. Eventually I started to try to export with every combination of them (DWG 2007, 2010, 2013), naming the file differently, in different folders, with different view types. It's still not exporting the parts of the drawing that I need.

(attached a C3D screenshot and the Autocad DWG export screenshot).

Can anyone please help on this one?

Thank you very much

Tty using ExportC3DDrawing.

That's exactly how I've exported. Several times, same bad result.

I tried with a backup of my file and it worked, so I suppose that my file is somehow bugged or corrupted, and there's no way to copy everything to another blank file, because after selecting all + CtrlC, a message says that 'the copy failed'.

Two days of work threw into the trash.

A few months ago I had a similar problem. in my case, only a few labels (alignment or station labels) were broken. I removed the annotations step by step to the point where the export works again and only repaired the annotations.

Maybe they are considered proxy objects.

If possible, simply upload your drawing for review.

Sorry. Export to AutoCAD is another command and almost never works. Another suggestion that you might have tried already. Do a Recover on the drawing.
