My drawing disappeared help!

Was working and was changing view as far as can remember and my drawing disappeared if I hit select all it says there are entities there but I can’t see any of them. HELP!!! I tried to upload it but it’s too big

Upload your file to Dropbox or Google Drive or something like it and share the link to your file here.

After digging into a few other posts I figured it out, apparently I was zoomed out to the moon. Thanks for the help
