|
|
Extrude a sketch along a path.
|
|
|
|
This, like extrude, is able to create a 3-dimensional solid from a 2-dimensional sketch. However, unlike extrude, this creates a solid by using the extent of the sketch as its path. This is useful for creating more complex shapes that can't be created with a simple extrusion.
|
|
|
|
You can provide more than one sketch to sweep, and they will all be swept along the same path.
|
|
|
|
By default, we set `sectional` to `true`, which means that the sweep will be broken up into sub-sweeps (extrusions, revolves, sweeps) based on the trajectory path components.
|
|
|
|
If your sweep fails, try setting `sectional` to `false` to create a single solid.
|
|
|
|
```js
|
|
sweep(
|
|
sketches: [Sketch],
|
|
path: SweepPath,
|
|
sectional?: bool,
|
|
tolerance?: number,
|
|
tagStart?: TagDeclarator,
|
|
tagEnd?: TagDeclarator,
|
|
): [Solid]
|
|
```
|
|
|
|
|
|
### Arguments
|
|
|
|
| Name | Type | Description | Required |
|
|
|----------|------|-------------|----------|
|
|
| `sketches` | [`[Sketch]`](/docs/kcl/types/Sketch) | The sketch or set of sketches that should be swept in space | Yes |
|
|
| `path` | [`SweepPath`](/docs/kcl/types/SweepPath) | The path to sweep the sketch along | Yes |
|
|
| `sectional` | [`bool`](/docs/kcl/types/bool) | If true, the sweep will be broken up into sub-sweeps (extrusions, revolves, sweeps) based on the trajectory path components. This defaults to true. | No |
|
|
| `tolerance` | [`number`](/docs/kcl/types/number) | Tolerance for this operation | No |
|
|
| `tagStart` | [`TagDeclarator`](/docs/kcl/types#tag-declaration) | A named tag for the face at the start of the sweep, i.e. the original sketch | No |
|
|
| `tagEnd` | [`TagDeclarator`](/docs/kcl/types#tag-declaration) | A named tag for the face at the end of the sweep | No |
|
|
|
|
### Returns
|
|
|
|
[`[Solid]`](/docs/kcl/types/Solid)

|
|
|
|
|
### Examples
|
|
|
|
```js
|
|
// Create a pipe using a sweep.
|
|
|
|
// Create a path for the sweep.
|
|
sweepPath = startSketchOn(XZ)
|
|
|> startProfileAt([0.05, 0.05], %)
|
|
|> line(end = [0, 7])
|
|
|> tangentialArc({ offset = 90, radius = 5 }, %)
|
|
|> line(end = [-3, 0])
|
|
|> tangentialArc({ offset = -90, radius = 5 }, %)
|
|
|> line(end = [0, 7])
|
|
|
|
// Create a hole for the pipe.
|
|
pipeHole = startSketchOn(XY)
|
|
|> circle(center = [0, 0], radius = 1.5)
|
|
|
|
sweepSketch = startSketchOn(XY)
|
|
|> circle(center = [0, 0], radius = 2)
|
|
|> hole(pipeHole, %)
|
|
|> sweep(path = sweepPath, sectional = false)
|
|
```
|
|
|
|
|
|
|
|
```js
|
|
// Create a spring by sweeping around a helix path.
|
|
|
|
// Create a helix around the Z axis.
|
|

|

|
|
|> circle(center = [0, 0], radius = 1)
|
|
|> sweep(path = helixPath)
|
|
```
