I have been struggling with this set of project drawings for months. I keep resetting the UCS to world and nothing changes.  I keep flattening all my elevations because otherwise my lines don't connect and I can't accurate trim anything.  I am at my wits end.  I don't know how to reset this drawing so it will stop making these errors when I make new elevation (it doesn't even do it consistently).  It will be fine for several drawings and then start acting up again.Dimensions are offsetting themselvesYX are skewed???
