The article has a small mistake, BRep stands for Boundary Representation, not Binary. Secondly, for point of reference, the basic design that the author uses as their benchmark that took them approximately an hour to an hour and a half to generate on these tools would, for me, an experienced user using a professional tool (CATIA in my case) take no longer than five minutes. Maybe more like sub 2 minutes if I was pushing it and the shape was known ahead of time. Just wanted to give people a perspective if they weren't aware of how quick something like that can be done by and experienced person using a professional tool.

Exactly. In my case, it would take 5 minutes in Solidworks. This really adds up when you design hundreds or thousands of parts and assemblies a year. The added cost of the software is negligible in comparison to the labor savings.

  I do a lot of electrical/mechanical codesign, and I save more than the cost of my SolidWorks license every time I don't have to re-fabricate any parts because everything fit together perfectly the first time.

Yep. Here's a video of a CAD competition, with experienced Onshape user modeling simple rectilinear parts[0]. Video is sped up, but live modeling took under 3 minutes per part[1] [0] https://www.youtube.com/watch?v=TzyI7xnGoPI https://www.youtube.com/watch?v=TzyI7xnGoPI [1] https://www.youtube.com/watch?v=Whw9RrZz6XI&t=2073s https://www.youtube.com/watch?v=Whw9RrZz6XI&t=2073s

  Of course there are CAD competitions. I love stuff like this, thank you.

"By an experienced person" is, I suspect, doing a lot more heavy lifting here than one might assume.

It is hard to say because it is not explicitly stated in the article, but I think the author was evaluating unfamiliar programs. Trying a program which you are unfamiliar with in a domain you are experienced in is very frustrating, your muscle memory is all wrong, the tools you would ordinarily use are missing, and you have no real feel for how the new tools would work. I give the author a pass for taking an hour and half on the shape.
