Good Morning All,
Strange question and while my first inkling is always that "you're never the first person who has run into this problem", my GoogleFu and searching of the AUGI forums haven't yielded any appreciable help.
A colleague was working on a drawing in AutoCAD MEP 2011, drawing a section of some equipment, followed by some work on a partial plan view. This was on Saturday Nov. 12. Today, when he opened the drawing, and lines and other objects drawn on the section disappeared, but everything on the partial plan view (that was drawn AFTER the section) were there.
We've tried all the obvious stuff like making sure layers are thawed and on, but I'm really at a loss as to what could be causing this to happen!
Thanks for your time!
