hi, this should be really simple, but its driving me crazy.

i just want to make a long rectangular object (for a train carriage) with rounded upper sides.
Ive tried to draw a curve and extrude a nurbs surface, but i cant get the shape of the curve right.
Can someone explain to me or tell me where to find out how to:
-add points to an already created curve
-adjust the points to be corner or tangent curves
-adjust the tangents of a point
...

i read through the help and several tuts, but none of them explain how to manipulate the curve in any depth

basically i want two hard corners at the bottom , and rounded edges around the top corners...

thanks

-add points to an already created curve : insert knot tool under edit curves - but that shouldn't have been too hard to find out for yourself :p

-adjust the points to be corner or tangent curves
-adjust the tangents of a point

you can't weight cvs in maya, there are no tangents too. Maya just interpolates your curves through your cvs in the given degree - mostly 3 - you can set it when creating your curve. For corners just place 3 points on each other with point snapping. (if you have a curve of degree 3)
