This is probably a stupid question, but i have the hang of nurbs in general, nice, curvey nurbs.
the thing that drives me crazy is trying to get sharp edges, for example, a square.

case in point: I click the create nurbs square button, a nice square comes up in the work area, but the edges are not attached?!! i'm like wtf, that's not a square !! it's just lines.

Now here's the thing, i can attach 3 of the sides together with the attach curves tool, and by playing with the settings, can keep sharp edges on it.
but i can't close the last corner.

i tried 'close curves'
and connect this and that, but it either won't connect the 2 verticies on the corner, or it creates a curve, not a corner, and it's a pain in the ass trying to wrestle that curve into the shape of a corner, and it slows down and kills my work flow.

I read the help and tuts and docs, but can't see anything, although knowing me it's probably staring me right in the face,
any solutions to this prob? thanks guys.

Adam.
