Frequently Asked Questions
Which controller series is supported?
Check the release notes for the exact firmware matrix; each major version supports a defined controller range, and newer firmware usually requires a newer engineering tool.
Is a license dongle required?
Licensing is typically node-locked or dongle-based; a trial mode is usually available for evaluation.
Can older projects be opened?
Projects migrate forward release by release. Keep a backup copy of the original project before converting it to a newer version.
Does it run in a virtual machine?
Yes, VMware or VirtualBox work for programming and testing; enable nested acceleration if you use the built-in simulator.

Tips from Real Projects
A robot-cell fixture went through three design iterations in one week in Siemens NX2406, and the third one was the first the welder could actually reach. The discipline that helped: modeling to the manufacturing method — bends, weld prep, and machining stock included — so the drawing followed the model instead of fighting it. Export with named coordinate frames when the file goes to offline programming; unnamed frames cost the robot team an afternoon of guessing.
