Quick question for all you experts. I'm new to sketchup, so there's probably an easy fix for this. Hopefully.

I have a hidden object somewhere in the white space and I can't locate it or delete it. When I hit zoom extents, it zooms way out from my drawing (like several hundred feet in scale), but there is nothing visible in the white space. When I try to do a section pane, it does the same thing and sections an area several hundred feet in all directions, with nothing visibly showing.

I've turned on all layers. And I made every white colored layer black.
I've gone through every item in outliner
I've scribbled the eraser all over the white space trying to find some dot of a line or anything just floating out there.
I've dragged left with the dotted "select everything" box and nothing happens.

I'm stumped.

Any suggestions?
