Draw a NURBS curve freehand
- Select
Create > Pencil Curve Tool.

the mouse button Maya creates the curve.
- The Pencil Curve tool creates
a curve with a large number of data points. Use
Edit Curves > Rebuild Curve to
simplify the curve.
- As you draw the curve, Maya puts points
in the view if they are at least five screen pixels from the previous
point.
- If you sketch in an orthographic view
(front, top, or side), Maya creates the curve on the view plane
at the origin. If you sketch in the perspective view, Maya creates
the curve on the grid plane.
