Create a surface within bounding curves
 
 
 
  1. Select the boundary curves.

    If you select only three curves, Maya will create a “three-sided” surface (see notes below).

  2. Choose Surfaces > Boundary.

    If you turn on the Partial option to use a subsection of the curves, you can control which part of each curve Maya revolves by selecting the subcurve node in the channel box and editing the minValue and maxValue attributes. If you have the Show Manipulator tool selected, handles appear on the curves to allow you to drag the values.
