|
Starting at the current sketch's origin, draw a curved line segment along some part of an imaginary circle until it reaches the desired (x, y) coordinates.
|
|
|
|
```kcl
|
|
tangentialArc(
|
|
@sketch: Sketch,
|
|
endAbsolute?: Point2d,
|
|
end?: Point2d,
|
|
radius?: number,
|
|
angle?: number,
|
|
tag?: TagDeclarator,
|
|
): Sketch
|
|
```
|
|
|
|
When using radius and angle, draw a curved line segment along part of an imaginary circle. The arc is constructed such that the last line segment is placed tangent to the imaginary circle of the specified radius. The resulting arc is the segment of the imaginary circle from that tangent point for 'angle' degrees along the imaginary circle.

### Arguments
|
|
|
|
| Name | Type | Description | Required |
|
|
|----------|------|-------------|----------|
|
|
| `sketch` | [`Sketch`](/docs/kcl-std/types/std-types-Sketch) | Which sketch should this path be added to? | Yes |
|
|
| `endAbsolute` | [`Point2d`](/docs/kcl-std/types/std-types-Point2d) | Which absolute point should this arc go to? Incompatible with `end`, `radius`, and `offset`. | No |
|
|
| `end` | [`Point2d`](/docs/kcl-std/types/std-types-Point2d) | How far away (along the X and Y axes) should this arc go? Incompatible with `endAbsolute`, `radius`, and `offset`. | No |
|
|
| `radius` | [`number`](/docs/kcl-std/types/std-types-number) | Radius of the imaginary circle. `angle` must be given. Incompatible with `end` and `endAbsolute`. | No |
|
|
| `angle` | [`number`](/docs/kcl-std/types/std-types-number) | Offset of the arc in degrees. `radius` must be given. Incompatible with `end` and `endAbsolute`. | No |
|
|
| [`tag`](/docs/kcl-std/types/std-types-tag) | [`TagDeclarator`](/docs/kcl-lang/types#TagDeclarator) | Create a new tag which refers to this arc | No |
|
|
|
|
### Returns
|
|
|
|
[`Sketch`](/docs/kcl-std/types/std-types-Sketch) - A sketch is a collection of paths.
|
|
|
|
|
|
### Examples
|
|
|
|
```kcl
|
|
exampleSketch = startSketchOn(XZ)
|
|
|> startProfile(at = [0, 0])
|
|
|> angledLine(angle = 45, length = 10)
|
|
|> tangentialArc(end = [0, -10])
|
|
|> line(end = [-10, 0])
|
|
|> close()
|
|
|
|
example = extrude(exampleSketch, length = 10)
|
|
```
|
|
|
|
|
|
|
|
```kcl
|
|
exampleSketch = startSketchOn(XZ)
|
|
|> startProfile(at = [0, 0])
|
|
|> angledLine(angle = 60, length = 10)
|
|
|> tangentialArc(endAbsolute = [15, 15])
|
|
|> line(end = [10, -15])
|
|
|> close()
|
|
|
|
example = extrude(exampleSketch, length = 10)
|
|
```
|
|
|
|
|
|
|
|
```kcl
|
|
exampleSketch = startSketchOn(XZ)
|
|
|> startProfile(at = [0, 0])
|
|
|> angledLine(angle = 60, length = 10)
|
|
|> tangentialArc(radius = 10, angle = -120)
|
|
|> angledLine(angle = -60, length = 10)
|
|
|> close()
|
|
|
|
