|
||
|
||
Start a new 2-dimensional sketch at a given point on the 'XY' plane.
|
||
|
||
|
||
|
||
```js
|
||
startSketchAt(data: [number]) -> SketchGroup
|
||
```
|
||
|
||
### Examples
|
||
|
||
```js
|
||
const exampleSketch = startSketchAt([0, 0])
|
||
|> line([10, 0], %)
|
||
|> line([0, 10], %)
|
||
|> line([-10, 0], %)
|
||
|> close(%)
|
||
|
||
const example = extrude(5, exampleSketch)
|
||
```
|
||
|
||
|
||
|
||
```js
|
||
const exampleSketch = startSketchAt([10, 10])
|
||
|> line([10, 0], %)
|
||
|> line([0, 10], %)
|
||
|> line([-10, 0], %)
|
||
|> close(%)
|
||
|
||
const example = extrude(5, exampleSketch)
|
||
```
|
||
|
||
|
||
|
||
```js
|
||
const exampleSketch = startSketchAt([-10, 23])
|
||
|> line([10, 0], %)
|
||
|> line([0, 10], %)
|
||
|> line([-10, 0], %)
|
||
|> close(%)
|
||
|
||
const example = extrude(5, exampleSketch)
|
||
```
|
||
|
||
|
