Use the Tube command to extend any Morph face into a tube, changing directions and planes as many times as you like.
1.Click anywhere on a Morph face.
2.From the pet palette, choose the Tube command.
3.Start drawing the Tube, clicking to place each segment in turn.
Note: The first segment must be drawn perpendicular to the clicked face.

4.Double-click to complete the Tube.
