Unigraphics, MasterCAM, Verisurf... Until ported to LINUX I’m stuck in the MS world. I doubt it’s going to happen anytime soon. When you’re in the realm of software I’m using the last consideration is how much the OS costs. It’s what’s supported.
There’s also simply unplugging from the internet. Not always practical for me BUT, some of my machines are offline.
Linux is good for someone who just wants to browse and check email. But not a workstation in the engineering world.
You might want to look again. I just a few quick searches via google and found success with the three you named on linux. Some links go back to 2009.
I beg to differ. I use multiple Linux workstations in the engineering world. I support ~1,000 Linux servers across multiple data centers, all doing heavy duty research and database crunching.
Linux works much better for me than any Windows would.
