I have a drawing file for a job with about 20 layers in a variety of scales from 1:10 - 1:200. I now cannot create a new layer with a scale other than what I already have. I get a message saying "proposed combination of units and scale would create an invalid drawing environment. Please switch to a larger unit or reduce the range of your layer scales." This also comes up when I first open the file.
I am working in millimeters units with internal accuracy set at 0. I have also tried setting this to other amounts but it doesn't seem to help.
I have zoomed right out to check if there's any strange objects floating outside the page but can't see anything...
Help, this is really frustrating me...!!!!
