I am having trouble with some of my 3D geometry going missing after I have saved the drawing. Running AutoCAD 2013, Saving file Format 2010. I draw a room. I have walls, chairs, desks, a floor, ect. I save the drawing. When going to re-open the file I can see all of my geometry in the file preview, but when opening the DWG the floor is missing. All Layers are on and thawed. When running a purge command it indicates that something is on the layer, but I can't see it or select it. Changing visual styles also has no effect. Are there any thoughts as to what is happening, how I can fix it, and how to avoid it in the future. I have used CAD in 3D since CAD 2000 and have never had this issue. Any input is appriciated. Thank you.
Did you try an 'AUDIT'..?
Hardware acceleration / viewport degradation settings?
Graphic card drivers / type?
ran an Audit, no objects were deleted.
ATI FirePro v4800 video card This is a relativly low detail drawing so I don't think we are having card issues. Also I have run it on 3 seperate machines of different set ups and had the same results.

You should be aware that this preview is a bitmap snapshot created automatically at some point and is not indicative of the actual geometry within the file. In other words - it is a picture, not geometry.
Attach your file here.
I have had success recovering "lost" geometry like this using other CAD programs (but I haven't seen this problem in AutoCAD since v2010). Edit - I see you saved to v2010. Well you might be in luck if you attach the file here.
the file limit is much larger over here http://w.augi.com
This is what I see in the file (in another CAD program).
Is there geometry in this image that is missing when you open in AutoCAD?
Edit: Never mind - just checked the Preview on the AutoCAD file. I will try to dig a bit deeper and see if I can recover anything.
