In the middle of drawing a 3D model using solids, when I orbited the model it suddenly disappeared and I can't get it back. I have shut down the program and reopened the file and it is just "empty" like it was totally erased. I tried using different View Styles and still nothing.

Please help.

Hi
What version are you using?
What is the size of the file now and before?
Is the a backup? (will be in the same folder as the parent dwg but named as '.bak')
Also worth looking in the '$SV' folder for an autosaved backup.

Looks like a graphics issue, so try switching the CMS IntelliCAD graphics settings to OpenGL or OpenGL ES ( intermediate to advanced).
Check GRAPHICSCONFIG command .

The purpose of checking file sizes is to assess if anything has been deleted.
