Because it's built on Parasolid, the same geometric kernel as everyone else. With ACIS pretty much out the door, almost all the professional CAD packages are just window dressing on the same CG implementation.
The actual UI still needs a lot of work, but I’ve been focused on the kernel. Fable has helped a lot though Opus was already making great headway.
I’m an OnShape power user going back about ten years, Solidworks before that. I need a CAD system that absolutely works. There is a lot of work to do still, and it still seems impossible to succeed, but I’ve been very happy with where things have been going with it lately.
It’s serverless, local, and browser based. You can load the latest binary from GitHub pages here:

Click the Assay menu to see the kernel test cases we’ve been using so far. Rapidly closing on 100% support!
