What happened to the Mirror Body command in NX?
Solution
Several similarly functioning commands, including the Mirror Body command, were consolidated into a single "Extract Geometry" command. Select "Menu --> Insert --> Associative Copy --> Extract Geometry" and change the uppermost drop-down menu to "Mirror Body".
Alternatively, you can enter "Mirror Body" into the Command Finder.
