Select: +

1) a plane on which to sketch a circle to

define the helix cross-section.

or

2) a sketch that contains a single circle.

If we don't exit the sketch, we'll only have the "Helix and Spiral" option from

the "Curves" command. If we select the "Helix and Spiral" before exiting

the sketch, the sketch will be automatically selected.

The helix is defined by selecting two parameters between Pitch,

Revolutions, and Height; the third parameter is automatically calculated from the

other two. For this example, we'll select "Pitch and Revolution" from the "Defined

By:" drop down menu, and make the pitch 0.325" with 6 Revolutions. The "Start

Angle" value defines where the helix will start. By setting it to 90 degrees we are

defining the start of the helix at the top, coincident with the "Front Plane." If we had

made it 0 degrees, it would be coincident to the "Top Plane" instead. (Feel free to

explore the options.) Click OK to complete the helix.
