From the Wireframe section of the action bar,
click Spiral
.
The Spiral panel appears.
In the work area,
select the reference elements:
A support
This element is the supporting plane for the spiral.
A center point
This element is the starting point for the spiral.
A reference direction
This element is the direction along which the radius of the spiral is measured,
and from which the angle of the spiral is computed.
In the 3D area, a
preview of the spiral appears.
In the panel, enter a value in the Start radius box.
This value corresponds to the distance from the center point, along the reference
direction, where the spiral's first revolution starts.
Under Orientation, select the direction of the spiral's
rotation:

Description
Angle and Radius
The spiral is defined by an end angle and an end radius. This means that the
last revolution ends on a point whose distance from the center point is the end radius
value.
Angle and Pitch
The spiral is defined by an end angle and a pitch. The pitch is the distance
between two revolutions of the spiral.
Pitch and Radius
The spiral is defined by an end radius and a pitch. The spiral ends when the
distance from the center point to the spiral's last point equals the end radius
value.
