Creating Spirals

Spiral lets you create curves in the shape of spirals, that is in 2D plane, as opposed to the helical curves.

Before you begin: Create a 3D shape containing a surface and an axis or a point.
  1. In the Support box, select a supporting plane for the spiral.
  2. In the Center point box, select the center point for the spiral.
  3. In the Reference direction box, specify the direction along which the radius value is measured and from which the angle is computed, when the spiral is defined by an angle.
  4. In the Start radius box, specify the value of the start radius. It is the distance from the Center point, along the Reference direction, at which the spiral's first revolution starts.
  5. In the Orientation box, define the spiral's orientation, that is the rotation direction: clockwise or counterclockwise.
  6. In the Type list, select the spiral creation mode, and define the corresponding values.
  7. Click OK to create the spiral curve.
