I think what you are looking for is found in Non-Cutting moves on the Avoidance page - From and Gohome points.
Do you have access to the documentation? It is installed separately from NX.
The documentation is found by going to Menu > Help > NX Help.
If you get a message that the system us uable to display Help information or cannot find an HTML file, then help is not installed on your system or network. You need to install the documention kit in addition to installing NX.
