|
Start a new 2-dimensional sketch on a specific plane or face.
|
|
|
|
|
|
|
|
```js
|
|
startSketchOn(data: SketchData, tag?: FaceTag) -> SketchSurface
|
|
```
|
|
|
|
|
|
### Arguments
|
|
|
|
| Name | Type | Description | Required |
|
|
|----------|------|-------------|----------|
|
|
| `data` | [`SketchData`](/docs/kcl/types/SketchData) | Data for start sketch on. You can start a sketch on a plane or an solid. | Yes |
|
|
| `tag` | [`FaceTag`](/docs/kcl/types/FaceTag) | A tag for a face. | No |
|
|
|
|
### Returns
|
|
|
|
[`SketchSurface`](/docs/kcl/types/SketchSurface) - A sketch type.
|
|
|
|
|
|
### Examples
|
|
|
|
```js
|
|
exampleSketch = startSketchOn("XY")
|
|
|> startProfileAt([0, 0], %)
|
|
|> line(end = [10, 0])
|
|
|> line(end = [0, 10])
|
|
|> line(end = [-10, 0])
|
|
|> close()
|
|
|
|
example = extrude(exampleSketch, length = 5)
|
|
|
|
exampleSketch002 = startSketchOn(example, 'end')
|
|
|> startProfileAt([1, 1], %)
|
|
|> line(end = [8, 0])
|
|
|> line(end = [0, 8])
|
|
|> line(end = [-8, 0])
|
|
|> close()
|
|
|
|

|
|
|> startProfileAt([2, 2], %)
|
|
|> line(end = [6, 0])
|
|
