# Bezier Helix
### Bezier Helix
A Bezier Helix shape provides an upward spiral with a constant radius.
| Parameter | Type | Description |
| ----------- | -------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Smooth Mode | Options (Smooth, Circular, Hard) | Choose an option to automatically assign a circularity to Smooth (2), Circular (1), or Hard (0) |
| Circularity | Decimal (0-2) | A rating of anchor weighting to provide different levels of smoothness. 2: the shape is smoothed at its control points. 1: The shape is perfectly circular. 0: The shape is made of straight lines |
| Radius | Decimal (Meters) | The distance from the center of the helix to the horizontal extends of the helix |
| Segments | Integer | The number of spline segments to use for each turn |
| Height | Decimal (Meters) | The distance from the bottom of the helix to the top of the helix (y-axis) |
| Num Turns | Decimal | Represents the number of circles that the helix is made up of. Can support partial loops |
| Start Angle | Decimal (Degrees) | Indicates the starting angle (around the centroid) that the helix starts. |
