i found that creating curbs using the beam tool with a complex profile is fine for simple flat sites. if you need some change of elevation, angled beams do OK too. where it gets tricky, is when you have one end of beam curb that's lower, the other end is higher AND it's a curve. i found that you can't have curved angled beams higher at one end than the other. maybe a morph tool using the same complex profile will work -- i haven't tried it yet.
with regards to your video question, after you've drawn the first straight curb, instead of clicking the button in the pet palette for a curve, keep drawing the straight curb for both curves for now. re-select the beams, then edit them to be curves. (shared video below. i hope it works)
