What happened to my drawing?

I was working on a file and imported a 3-D warehouse file and decided I didn’t want it so deleted it and now my whole model is invisible. The file is large and I see in Outliner that there should be groups. But I don’t see them. I tried “unhide”. Any suggestions?

Camera’s just not looking at the model. Press Zoom Extents. You should see something along these lines.

Dave beat me again.
Purging the file makes the file size go down from 14 MB to less than 250 KB

Thank you! Will do!
