Today after working with the machine operator on a very complex job we decided that one tool needs to have its own work offset, no problem, I thought. I created a new MCS and added the new fixture offset. To my amazement when I edited the operation some strange things started to happen. 1.) When I selected the new geometry object, yes the only geometry objects are MCS objects, the operation navigator changed to the geometry view. 2.) The operation I changed went to the bottom of the current program group. This is DANGEROUS. This is an existing program and all I wanted to do was, IMHO, make a simple change. If we cannot trust the software to make a simple change like this we are going to be second guessing everything we do.
Yes, I submitted an IR # 7224337 with a . avi of this
I am running 8.5 and now that I see this thread I think it happened to me just the other day. I will have to got try that agian.
Moving the operation to the endor the program group is not expected, so glad you logged the IR, which has been converted to a PR. I am sure it has to do with the instances. Without those, the operation stays right where it is in the program group.
Regarding the Operation Navigator view changing to geometry, I have never seen that, and I cannot duplicate it, even in your part, in 9.0.3 MP2. I'll let the GTAC folks take a closer look at it.
I will get the MP's downloaded and installed.
If all goes well, NX 9.0.3 MP2 should be available by the end of the week.
Don't forget that there is additional functionality in MP1 and MP2, so be sure and review the Product Notes and What's New Guide.
I know this has been a while, but this issue has cost me countless hours throughout the years. See the docs below. I am on NX 18.104.22.168 NX1201_7_delta., 25Jan2018.
We are constantly switching which machine we are on and altering and moving operations from one Geometry group to another. Often I spend 20-30 min or more reorganizing the operations (sometimes 100 of ops) for something as simple as a MCS change. This used to be a 5 min job. As a shop that uses many CAM software's, and carefully decides whether or not they will be paying their maintenance, the time it takes for these simple fixes has raised eyebrows on the floor and with management on many occasions, not to mention the inherent danger, without even a warning that your operations have been reordered!!!!!
While it may be working as designed, the way this is designed is not working for us.
Below is a line from the docs. What!!!! Who sets their order in the Geometry page?!?!
"If you want to plan your NC program based on geometry, use the Geometry View instead of the Program Order View. You can then organize the setup by geometric feature."
