You can use the Training tab in the resource bar in NX to display the courses, if you are working in the Windows operating system.
The resource bar will display the page defined by the UGII_CAST_HOME environment variable, which is set during installation of CAST.
When you have CAST displayed in the resource bar, and you must display one of the NX Navigators, you should undock the Navigator window so that you can see the Navigator and the training at the same time.
