title: "chamfer"

subtitle: "Function in std::solid"
|
|
excerpt: "Cut a straight transitional edge along a tagged path."
|

---
|
|
|
|
Cut a straight transitional edge along a tagged path.
|
|
|
|
```kcl
|
|
chamfer(
|
|
@solid: Solid,
|
|
length: number(Length),
|
|
tags: [Edge; 1+],
|
|
tag?: TagDecl,
|
|
): Solid
|
|
```
|
|
|
|
Chamfer is similar in function and use to a fillet, except
|
|
a fillet will blend the transition along an edge, rather than cut
|
|
a sharp, straight transitional edge.
|
|
|
|
### Arguments
|
|
|
|
| Name | Type | Description | Required |
|
|
|----------|------|-------------|----------|
|
|
| `solid` | [`Solid`](/docs/kcl-std/types/std-types-Solid) | The solid whose edges should be chamfered | Yes |
|
|
| `length` | [`number(Length)`](/docs/kcl-std/types/std-types-number) | The length of the chamfer | Yes |
|
|
| `tags` | [`[Edge; 1+]`](/docs/kcl-std/types/std-types-Edge) | The paths you want to chamfer | Yes |
|
|
| `tag` | [`TagDecl`](/docs/kcl-std/types/std-types-TagDecl) | Create a new tag which refers to this chamfer | No |
|
|
|
|
### Returns
|
|
|
|
[`Solid`](/docs/kcl-std/types/std-types-Solid) - A solid is a collection of extruded surfaces.
|
|
|
|
|
|
### Examples
|
|
|
|
```kcl
|
|
// Chamfer a mounting plate.
|
|
width = 20
|
|
length = 10
|
|
thickness = 1
|
|
chamferLength = 2
|
|
|
|
mountingPlateSketch = startSketchOn(XY)
|
|
|> startProfile(at = [-width / 2, -length / 2])
|
|
|> line(endAbsolute = [width / 2, -length / 2], tag = $edge1)
|
|
|> line(endAbsolute = [width / 2, length / 2], tag = $edge2)
|
|
|> line(endAbsolute = [-width / 2, length / 2], tag = $edge3)
|
|
|> close(tag = $edge4)
|
|
|
|
mountingPlate = extrude(mountingPlateSketch, length = thickness)
|
|
|> chamfer(
|
|
length = chamferLength,
|
|
tags = [
|
|
getNextAdjacentEdge(edge1),
|
|
getNextAdjacentEdge(edge2),
|
|
getNextAdjacentEdge(edge3),
|
|
getNextAdjacentEdge(edge4)
|
|
],
|
|
)
|
|
|
|
```
|
|
|
|
|
|
|
|
```kcl
|
|
// Sketch on the face of a chamfer.
|
|
fn cube(pos, scale) {
|
|
sg = startSketchOn(XY)
|
|
|> startProfile(at = pos)
|
|
|> line(end = [0, scale])
|
|
|> line(end = [scale, 0])
|
|
|> line(end = [0, -scale])
|
|
|
|
return sg
|
|
}
|
|
|
|
part001 = cube(pos = [0, 0], scale = 20)
|
|
|> close(tag = $line1)
|
|
|> extrude(length = 20)
|
|
// We tag the chamfer to reference it later.
|
|
|> chamfer(length = 10, tags = [getOppositeEdge(line1)], tag = $chamfer1)
|
|
|
|
sketch001 = startSketchOn(part001, face = chamfer1)
|
|
|> startProfile(at = [10, 10])
|
|
|> line(end = [2, 0])
|
|
|> line(end = [0, 2])
|
|
|> line(end = [-2, 0])
|
|
|> line(endAbsolute = [profileStartX(%), profileStartY(%)])
|
|
|> close()
|
|
|> extrude(length = 10)
|
|
|
|
