We have a great problem in the nx11 version. When we are going back in the model tree to make some changes, and make an update some of the commands mixes up selected objects!
Example: I change a diameter of a hole or change the size in extended sheet with 0.1mm! in a model, and i use the edge in later to make an other sheet the selected edge changes from top to side or bottom, or perhaps the holes edge.
Or i dont need any changes i just make an update of the model and that makes every edge mixed!
In previous versions we had never such kind of an error!!!
When we get a patch to fix this error?
I agree with @StevenVickers that you should contact GTAC directly with this issue. I just wanted to add that NX 11.0.2 maintenance release is available for download. I'm not sure if it will solve your specific issue, but it is worth trying. Patching NX to the latest MR is probably the first thing that GTAC will have you try anyway...
