I made a drawing in Autocad 14 (Win XP) containing of mostly SOLID's. I saved and re-opened it multiple times without any problem. Before I last saved it I viewed my drawing using the SHADE functions.

After re-opening all my SOLIDS have disappeared. I spent numerous hours searching for a solution, tried SATFIX.ARX , AUDIT, RECOVER without success (ACIS error - which should be gone after applying SATFIX), changed my computer locale from German (decimal = comma) to English (decimal = dot) but my screen remains empty (and yes I tried to recover from a .BAK, too)

I also tried to export (the non-display drawing) into DXF and can confirm that all my objects are in there, but re-opening the DXF results in a huge ACIS error list again

I am desperate - please can someone help - thanks! Mike

Thanks Everyone for reading .... I found a solution:

using the trial version of PlotVision7 (http://www.torro.de/plotvision/) I opened my corrupt DWG and saved it as a DXF which I was able to open and further edit in ACAD R14. The DXF still contained some errors which you usually get when you open ACAD files with earlier program versions than you used to create, but at least these errors are non-blocking and all drawing objects appeared again.

The other kind of file that will be useful is the BAK file. This file is actually a copy of the file before the last save. This means that the first time that a file is saved, no BAK file will exist. The second time a drawing is saved, the BAK file will be created containing the information from the first save. These files are created in the same directory where the drawing is located. BAK files will only be created if the setting to create BAK files is toggled on. This can be found in the OPTIONS box under the Open and Save tab, “Create backup copy with each save.” Change the file extension from .BAK to .DWG, rename the file to something different than the original, and open it up in AutoCAD.

Compare the .SV$, .BAK, and the original .DWG to determine which is the most up-to-date, and that it contains all of the drawing data. Retain a backup of all of the original files, and rename the appropriate file to the original DWG name. Finally, there’s a chance that the drawing is corrupted. After saving the drawing run the AUDIT command choose YES to fix all the errors. You should now be ready to continue drawing.

Particular commands tend to crash the program more than others like hatch and 3d orbit. It is a good idea to QSAVE before you run these commands, or any others you find that crash the program.
