Modify > Convert > Polygon Edges to Curve

 
 
 

Form

Sets the type of curve that results once the selected edges are converted.

Open

Creates a curve with disconnected start and end points.

Periodic

Creates a curve with connected start and end points. If the selected edges do not form a closed loop, Maya will automatically connect the two open endpoints.

Best Guess

Creates a Periodic curve if the selected edges form a closed loop. Creates an Open curve otherwise.

Degree

The higher the Curve Degree, the more control you have over the curve’s smoothness. The default setting (3 Cubic) works well for most curves.
