Create a helix.
|
|
|
|
|
|
|
|
```js
|
|
helix(
|
|
revolutions: number(_),
|
|
angleStart: number(deg),
|
|
ccw?: bool,
|
|
radius?: number(mm),
|
|
axis?: Axis3d | Edge,
|
|
length?: number(mm),
|
|
cylinder?: Solid,
|
|
): Helix
|
|
```
|
|
|
|
|
|
### Arguments
|
|
|
|
| Name | Type | Description | Required |
|
|
|----------|------|-------------|----------|
|
|
| `revolutions` | `number(_)` | Number of revolutions. | Yes |
|
|
| `angleStart` | `number(deg)` | Start angle (in degrees). | Yes |
|
|
| `ccw` | [`bool`](/docs/kcl/types/bool) | Is the helix rotation counter clockwise? The default is `false`. | No |
|
|
| `radius` | `number(mm)` | Radius of the helix. | No |
|
|
| `axis` | `Axis3d | Edge` | Axis to use for the helix. | No |
|
|
| `length` | `number(mm)` | Length of the helix. This is not necessary if the helix is created around an edge. If not given the length of the edge is used. | No |
|
|
| `cylinder` | [`Solid`](/docs/kcl/types/Solid) | Cylinder to create the helix on. | No |
|
|
|
|
### Returns
|
|
|
|
[`Helix`](/docs/kcl/types/Helix)
|
|
|
|
|
|
### Examples
|
|
|
|
```js
|
|
// Create a helix around the Z axis.
|
|
helixPath = helix(
|
|
angleStart = 0,
|
|
ccw = true,
|
|
revolutions = 5,
|
|
length = 10,
|
|
radius = 5,
|
|
axis = Z,
|
|
)
|
|
|
|
// Create a spring by sweeping around the helix path.
|
|
springSketch = startSketchOn(YZ)
|
|
|> circle( center = [0, 0], radius = 0.5)
|
|
|> sweep(path = helixPath)
|
|
```
|
|
|
|
|
|
|
|
```js
|
|
// Create a helix around an edge.
|
|
helper001 = startSketchOn(XZ)
|
|
|> startProfileAt([0, 0], %)
|
|
|> line(end = [0, 10], tag = $edge001)
|
|
|
|
helixPath = helix(
|
|
angleStart = 0,
|
|
ccw = true,
|
|
revolutions = 5,
|
|
length = 10,
|
|
radius = 5,
|
|
axis = edge001,
|
|
)
|
|
|
|
// Create a spring by sweeping around the helix path.
|
|
springSketch = startSketchOn(XY)
|
|
|> circle( center = [0, 0], radius = 0.5 )
|
|
|> sweep(path = helixPath)
|
|
```
|
|
|
|
|
|
|
|
```js
|
|
// Create a helix around a custom axis.
|
|

|
|

|
|

|
|
origin = [0, 0.25, 0]
|

|
|
)
|
|
|
|
// Create a spring by sweeping around the helix path.
|
|
springSketch = startSketchOn(XY)
|
|
|> circle( center = [0, 0], radius = 1 )
|
|
|> sweep(path = helixPath)
|
|
```
|
|
|
|
|
|
|
|
```js
|
|
// Create a helix on a cylinder.
|
|
|
|
part001 = startSketchOn(XY)
|
|
|> circle( center= [5, 5], radius= 10 )
|
|
|> extrude(length = 10)
|
|
