Autodesk Fusion 360 uses Qt gui library. Some screenshots of its UI : https://www.google.com/search?q=%22autodesk+fusion+360%22+ui...

Here are some more CAD apps using Qt: https://en.wikipedia.org/wiki/Category:Engineering_software_...

(Although Fusion 360 was launched June 2013, nobody edited the wiki page to include it yet.)

I never would’ve guessed F360 was Qt based. It almost looks like they’re all custom widgets, but I haven’t used Qt for a bit, so I could be wrong.
