I have been working on a factory floor layout. This 40'-0" number just appeared today, in the middle of the layout, and I have turned on/off every single layer to try to find what it belongs to, but no luck. Even when I turn off ALL layers, it's still there, sitting by itself. I have no 40' anything in the vicinity, so I can't figure it out.
How can I get rid of this thing?!
Thanks!
(and I would've attached an image, but my account hasn't been verified, and I don't know how long that takes)
