|
Mirror a sketch.
|
|
|
|
```kcl
|
|
mirror2d(
|
|
@sketches: [Sketch; 1+],
|
|
axis: Axis2d | Edge,
|
|
): Sketch
|
|
```
|
|
|
|
Mirror occurs around a local sketch axis rather than a global axis.
|
|
|
|
### Arguments
|
|
|
|
| Name | Type | Description | Required |
|
|
|----------|------|-------------|----------|
|
|
| `sketches` | [`[Sketch; 1+]`](/docs/kcl-std/types/std-types-Sketch) | The sketch or sketches to be reflected. | Yes |
|
|
| `axis` | [`Axis2d`](/docs/kcl-std/types/std-types-Axis2d) or [`Edge`](/docs/kcl-std/types/std-types-Edge) | The axis to reflect around. | Yes |
|
|
|
|
### Returns
|
|
|
|
[`Sketch`](/docs/kcl-std/types/std-types-Sketch) - A sketch is a collection of paths.
|
|
|
|
|
|
### Examples
|
|
|
|
```kcl
|
|
// Mirror an un-closed sketch across the Y axis.
|
|
sketch001 = startSketchOn(XZ)
|
|
|> startProfile(at = [0, 10])
|
|
|> line(end = [15, 0])
|
|
|> line(end = [-7, -3])
|
|
|> line(end = [9, -1])
|
|
|> line(end = [-8, -5])
|
|
|> line(end = [9, -3])
|
|
|> line(end = [-8, -3])
|
|
|> line(end = [9, -1])
|
|
|> line(end = [-19, -0])
|
|
|> mirror2d(axis = Y)
|
|
|
|
example = extrude(sketch001, length = 10)
|
|
```
|
|
|
|
|
|
|
|
```kcl
|
|
// Mirror a un-closed sketch across the Y axis.
|
|
sketch001 = startSketchOn(XZ)
|
|
|> startProfile(at = [0, 8.5])
|
|
|> line(end = [20, -8.5])
|
|
|> line(end = [-20, -8.5])
|
|
|> mirror2d(axis = Y)
|
|
|
|
example = extrude(sketch001, length = 10)
|
|
```
|
|
|
|
|
|
|
|
```kcl
|
|
// Mirror a un-closed sketch across an edge.
|
|
helper001 = startSketchOn(XZ)
|
|
|> startProfile(at = [0, 0])
|
|
|> line(end = [0, 10], tag = $edge001)
|
|
|
|
sketch001 = startSketchOn(XZ)
|
|
|> startProfile(at = [0, 8.5])
|
|
|> line(end = [20, -8.5])
|
|
|> line(end = [-20, -8.5])
|
|
|> mirror2d(axis = edge001)
|
|
|
|
// example = extrude(sketch001, length = 10)
|
|
```
|
|
|
|
|
|
|
|
```kcl
|
|
// Mirror an un-closed sketch across a custom axis.
|
|
sketch001 = startSketchOn(XZ)
|
|
|> startProfile(at = [0, 8.5])
|
|
|> line(end = [20, -8.5])
|
|
|> line(end = [-20, -8.5])
|
|
|> mirror2d(
|
|
axis = {
|
|
direction = [0.0, 1.0],
|
|
origin = [0.0, 0.0]
|
|
})
|
|
|
|
example = extrude(sketch001, length = 10)
|
|
```
|
|
|
|
|
|
|
|
```kcl
|
|
// Sketch on the face of a mirrored sketch, that has been extruded.
|
|
sketch0011 = startSketchOn(XY)
|
|
|> startProfile(at = [6.77, 0])
|
|
|> yLine(length = 1.27)
|
|
|> tangentialArc(endAbsolute = [5.96, 2.37])
|
|
|> tangentialArc(endAbsolute = [-6.2, 2.44])
|
|
|> tangentialArc(endAbsolute = [-6.6, 1.82])
|
|
|> yLine(length = -1.82)
|
|
|> mirror2d( axis = X )
|
|
|> extrude(length = 10)
|
|
|
|
sketch002 = startSketchOn(sketch0011, face = END)
|
