Running a CAD/CAM product is a Kobayashi Maru. You don't push stuff forward and you become SolidWorks; stale and only living off of the flywheel momentum of being the standard across everyone who isn't a F500 size business. Or you do what the NX team is trying to do and push fundamental technologies in the field, and the user base goes up in arms (often for good reason!) and accuses you of being a dumdum.
I was only an NX user for a year before the new sketcher came out, and I switched to it immediately because I have no muscle memory of the old one. I get why the old-hands hate it, but like... until Siemens removes the Legacy Sketcher feature flag, IDK what there is to complain about? You can keep using the old one while the NX team starts rolling real-world feedback into the new one - they have said that there are no date to remove the Legacy Sketcher and they are going to make sure most everyone is happy before they do.
Steven Marjieh is starting to post videos about the new sketcher and has a bunch of good tips (hint: turn on Create Persistent Relations to get that old dumb feel back). He seems to like the new one, which is saying a lot given he has probably the broadest CAD experience range of anyone who talks about this stuff publicly.
