Helix
The angle in degrees through which the Helix turns over its length
The direction of the axis of the Helix
The base point of the Helix axis
Pitch will return the linear distance along the axis direction that a helix spans in one complete turn (360 degrees)
The radius of the arc
public static Helix ByAxis(Point axisPoint, Vector axisDirection, Point startPoint, double pitch = 1, double angleTurns = 360)
Create a Helix. The helix always rotates clockwise about the supplied
axis direction. If viewing along the axis direction, the viewer will see
the point turning clockwise around the axis as it moves along the curve
in the direction of increasing parameter. Pitch is Distance the helix
moves in the axis direction per turn. This can be positive or negative.
