I went into the other base drawing that it is xref'd into, & it says "needs recover" next to it instead of "loaded". I then tried to recover my first drawing, it gave me the error "unable to recover this drawing"
the drawing was originally a .dgn we received from a client, I had it converted to .dwg, then proceeded to change it to our standards, like normal. what's irritating is I was working in the drawing yesterday with no problems!!!!!!!! after reading this post, I really don't see any solutions yet, so are there any suggestions other than intellicad?
