So a lot of our files were made with holes that are just extruded cuts because that was the way the older engineers in our office do it, and to make sure our DXFs for laser cutting are accurate, all of the threading detail is added to the dimension in the text area, and sometimes dimensions on sheet metal are marked as inside or outside.
However, whenever I open many of these files, the dimension shows up with the color of having changed since the drawing was last opened, and all of those details are wrong. If somebody besides me or the creator opens them and prints them, we end up with drawings missing thread notes and other important details on the shop floor getting parts half made, and also misquoted.
I know nobody is going in and deleting that info, it seems the software is reverting the dimension to it's original state for no reason without the part ever having been opened. Is this a known problem? Are there known and documented solutions?
I had that happen to me about 4 months ago on a project from last year. It turned out to be when I installed 2016 my notes favorites had to be formatted again because SW didn't recognize the previous versions folder of favorites. So if those notes were someones favorites file SW cannot find the information it is looking for. Example I have a 1/2-13 hole going into pre heat treated parts, I have special notes dictating tap drill diameter finish condition and thread cleaning necessary after grinding of the heat treat part. A little much for even hole wizard. So I create favorites notes that I can add in.
When we upgraded any drawings with any of my notes were lost. I had to re-establish SW to look for them in the proper locations.
I believe there is a thread here somewhere as well about that, because a lot of people lost hole diameter and all GD, & T symbols because the library was messed up with the 2016 install, it would not look in the proper folder as assigned.
Ok long winded, short answer is it might have been someone's favorites note that they used instead of manually typing in every word. So then it becomes an issue of SW not finding that folder and as far as I know there is no real error that pops up when that happens. Text just disappears.
