Moi and Brep?

MoI uses B-Reps, same as about 99.9% of other CAD programs.

It is very rare for a CAD program to store its geometry only in a CSG form, it doesn't really lend itself to doing operations on the edges such as fillets.

So what they're saying is kind of confusing since B-Rep _is_ the standard way for CAD.
