Earlier quoted context omitted.
I can't speak for Revit but people are looking to switch to Blender from 3dsMax. The problem is not that Blender can't do what 3ds can but it lacks industry standard tooling compatibility. But still a lot of people in the industry are starting the switch to Blender. So change is coming.
People are always talking about switching to Blender (me included) - but they don't. Because as sad as it is, once you start to actually work with it in serious projects, you noticed all the things that hobbyists who hail Blender as the second coming never care about. I wanted to give Blender another got at replacing Cinema 4D for us (since their new licensing). I got used to the UI, though it's not nearlly as intuit…
That said, C4D has always been pretty performant when I still used it, more than Maya or Max.
