Draw a NURBS curve freehand
- Select Create > Pencil Curve Tool.
- Drag to sketch a curve. When you release the mouse button Maya creates the curve.
- The 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.
