Im not really in the space but all the CAD things I see lately are browser based "cloud offerings"
Im not sure is CAD stuff is just served by a basic graphics card at this point or if there is some server side work going on.
OS doesnt mean that much when every industry decided that Chrome was going to be their VM
Hardcore CAD systems like Solidworks or CATIA still aren’t browser based.
No one is using that cloud crap professionally. The bread and butter of the CAD world is Windows PCs with tons of RAM and certified GPUs.
