Slow DWG drawing and "Scanning" message
My collegue has found an interesting problem in one of the drawings he worked on (AutoCAD 2010). Every operation on this rather large file started with a delay (about 10 seconds) accompanied with a progressbar "Scanning the drawing".
We have checked all usual suspects - purged the drawing, annotation scales, loaded applications, references - but nothing helped. It was strange that the same drawing worked OK on another computer. So we have also tested the influence of the graphics card but again - no success.
Finally we have compared the system variables on both computers and found the culprit. The variable SHOWLAYERUSAGE was "on" on the slow computer. Switching it off has fixed the problem.
