Hmm, it's been a while since I last tried it, but I remember the constraints being pretty much the same as other software. Maybe I should try again.

It's just a different implementation of exactly the same idea. I've used every parametric CAD software that exists (more or less) and their sketch constraint solvers are generally indistinguishable. They only differ in small details - can you select the midpoint of a line? can you have mirror constraints? are they vaguely stable when underconstrained? etc.
