Use a 2-dimensional sketch to cut a hole in another 2-dimensional sketch.
|
|
|
|
```kcl
|
|
subtract2d(
|
|
@sketch: Sketch,
|
|
tool: [Sketch; 1+],
|
|
): Sketch
|
|
```
|
|
|
|
|
|
|
|
### Arguments
|
|
|
|
| Name | Type | Description | Required |
|
|
|----------|------|-------------|----------|
|
|
| `sketch` | [`Sketch`](/docs/kcl-std/types/std-types-Sketch) | Which sketch should this path be added to? | Yes |
|
|
| `tool` | [`[Sketch; 1+]`](/docs/kcl-std/types/std-types-Sketch) | The shape(s) which should be cut out of the sketch. | Yes |
|
|
|
|
### Returns
|
|
|
|
[`Sketch`](/docs/kcl-std/types/std-types-Sketch) - A sketch is a collection of paths.
|
|
|
|
|
|
### Examples
|
|
|
|
```kcl
|
|
exampleSketch = startSketchOn(XY)
|
|
|> startProfile(at = [0, 0])
|
|
|> line(end = [0, 5])
|
|
|> line(end = [5, 0])
|
|
|> line(end = [0, -5])
|
|
|> close()
|
|
|> subtract2d(tool = circle(center = [1, 1], radius = .25))
|
|
|> subtract2d(tool = circle(center = [1, 4], radius = .25))
|
|
|
|
example = extrude(exampleSketch, length = 1)
|
|
|
|
```
|
|
|
|
|
|
|
|
```kcl
|
|
fn squareHoleSketch() {
|
|
squareSketch = startSketchOn(-XZ)
|
|
|> startProfile(at = [-1, -1])
|
|
|> line(end = [2, 0])
|
|
|> line(end = [0, 2])
|
|
|> line(end = [-2, 0])
|
|
|> close()
|
|
return squareSketch
|
|
}
|
|
|
|
exampleSketch = startSketchOn(-XZ)
|
|
|> circle(center = [0, 0], radius = 3)
|
|
|> subtract2d(tool = squareHoleSketch())
|
|
example = extrude(exampleSketch, length = 1)
|
|
|
|
```
