There's a lot of great RUclips content showing how to use Siemens NX. This channel focuses on troubleshooting and problem solving. Unlike the channel name, the videos do not focus purely on NX, you'll find some that also include steps setting up BMIDE and Teamcenter to work with NX. These are videos I've recorded over the years to provide steps and solutions to issues that other NX users were experiencing. I hope you find them helpful. While the contents of the parts aren't intricate, you can see how NX is able to function and complete complex tasks with even basic data. Unfortunately there is no audio with these videos - maybe one day in the future I'll start recording them with audio (and perhaps re-record the existing ones) as looking back over them I can see how much more useful they would have been with an explanation. Don't forget to give a thumbs up if you like them and subscribe if you want to get notified of any new videos which I'm typically recording each week.
