We have some shaft drawings that were revised a couple of years ago and saved in our PDM system as image files. It was done probably in Wildfire2. We now realize that the tolerance went from, say,5.000/4.997 to 5.002/4.999 in that revision. That revision was to simply add a note to the drawing and had nothing to do with dimensions or tolerances. Scary, I know.
I open these drawings today with Wildfire4 and the tolerance is back to 5.000/4.997 as it should be. So I don't know what happened.
Short of doing a bunch of forensics and reloading old versions/builds of Pro/E, does this sound familiar to anyone? We're not worried about the shaft drawings that have been discovered, rather, I hope that if this is a known bug we could track down other drawings with modified dimension tolerances.
