Autocad 2009 seems to open files partially without asking or notifying us.
We have drawings that we just setup from scratch (using arch xrefs for background). When we open the file the xrefs seem to be gone but they are loaded, all layers turned on/thawed and nothing is clipped.
After a couple of hours of trying to figure this out, I tried to purge the drawing and this message showed up, "PURGE cannot be used on partially opened drawings".
So it appears that autocad decided that it wants to partially open the drawing with no notification. It was also noted that if the file was partially opened that you could not "saveas" any version other than 2007.
We have also noticed that if we open the file from explorer (double click the file) an autocad message appears. The message says "This drawing contains a large number of annotation scales. Do you want to reset the scales list?" If we click "yes" it seems to open the file normally from then on (if we save).
We find this totally unacceptable to have files that might or might not fully load all layers (or anything else being suppressed). At this time we have told everyone to stop using the 2009 version of autocad.
We might have missed something in the documentation with regard to this problem. If so we would appreciate it if someone could point us in the right direction.
At this time we will not be using 2009 until we are 100% sure that all of our files will always fully load.
