How would I implement a "rail revolve?"

If any of you have used the Nurbs modeling program Rhinoceros, they have a tool called Rail Revolve. I've been trying to figure out how to do this in Maya but i cant do it. Any help would be great?

If you dont know what Rail Revolve is, its basically taking a Profile Curve and revolving it around a Rail you specify.

extrude?

Birail

this is close to what you are talking about.
there are multiple rail/birail functions in maya that , in playing with them you could achive a similar result to the tool in rhino.

but there is another neet feature that a lot of people dont know about that can do somehting similar.

animated sweep in the animation section of maya.

simply select a curve and keyfram an animation than go to the end of the animation and select animated sweep. it will fill the animation in as a surface.

so you could animate a curve along another curve and animate that sweep and get a similar result.

play with it a while. its really fun. if you want more info on how to do it you can email me.
