I have a couple of supports that needs to be placed in reference to a couple of flanges to the right of a couple of valves.
I did this by first selecting the support, then selecting type of mate and then selecting the flange. I did this for all necessary mates (coincident, concentric, etc). To make sure that nothing would get messed up in the future I even used the "use for positioning only" option whenever possible.
The only thing was that I got the "The selected fitting is controlled by te route. Using it for mates might change route geometry as well as its driving state." . Never the less once one pressed the "ok" button all went according to plan.
I did this for both supports. It worked. No unexpected nor unwanted behaviour. Supports where located where needed. All that was left to do was FIX them so that they couldn't be moved accidently.
However the system crashed due to me trying to print out a drawing that I had open and our IT switching print servers at that time.
I hadn't saved so I had to do it all over again. Hey, 5 minutes work at the most, no problem, right ?
Wrong, Instead the system doesn't let me do anything anymore involving the right side flanges because of the familiar "The route sketch is driving the position of this fitting.........". Which means that try as I might there's no way that I can make the mates that I was able to before the crash.
However, if I now use the flanges on the left side of the valves I can use the method that used to work previously on the right side flanges.
And then people wonder why I'm a nervous wreck.
