Bingo!! the problem solve guys.
uncheck the " make new dimension associative" box, that auto change dims is stop. This make me very excited. waste so much time to deal with this problem!!!
I am having similar issues.. I do not understand why paper space dimensions are changing....
I cannot find any scaling changes.. it is still at 1.0
This annoyingly frustrating
I am having trouble with the PS dimesion scale going from 64 to -4096. It does it on its own and at wierd times. If I drag the grip on a dimesion it will change and it will change some of the other dimensions as well but not all of them. If I hit undo it will go back. or if I hit match peoperties it will also go to the correct scale. This has been a persistant problem but only on some of my work. I don't know if there is something corrupt in the file I am using.
This is anoying not to mention dangerous. I don't believe any of my work has gone out with inccorect dimesions but I should not have to be checking for it.
I am currently running 2014 but this was happening on these files when I was running 2009. I am attaching the file so hopfully you can help me.
