In NX, assembly is saved after setting "Set Precise on Save".
Now user wants to undo the save operation.
He also want to hide this context menu option "Set Precise on Save"
Solution
It's not possible to hide "Set Save on Precise".
You can unset the precise save by following below method.
When you save an assembly by setting "Precise on Save", it saves the assembly with precise structure.
You can verify it in NX, in Assembly Navigator column "Precise Structure" it shows "Precise" Icon against the component nodes.
In TC, send the assembly to structure manager, all the nodes will be shown in "Green Color" to indicate precise structure.
You can unset the precise structure in TC, in structure manager, expand all the nodes & select them, now select Edit > Toggle Precise/ Imprecise.
This will make the assembly structure as imprecise and green color will be removed.
Similarly in NX, Assembly Navigator column "Precise Structure" will show "empty" against component nodes.(removing the precise icon)
