|
|
Set the appearance of a solid. This only works on solids, not sketches or individual paths.
|
|
|
|
```kcl
|
|
appearance(
|
|
@solids: [Solid; 1+] | ImportedGeometry,
|
|
color: string,
|
|
metalness?: number(_),
|
|
roughness?: number(_),
|
|
): [Solid; 1+] | ImportedGeometry
|
|
```
|
|
|
|
This will work on any solid, including extruded solids, revolved solids, and shelled solids.
|
|
|
|
### Arguments
|
|
|
|
| Name | Type | Description | Required |
|
|
|----------|------|-------------|----------|
|
|
| `solids` | [`[Solid; 1+]`](/docs/kcl-std/types/std-types-Solid) or [`ImportedGeometry`](/docs/kcl-std/types/std-types-ImportedGeometry) | The The solid(s) whose appearance is being set. | Yes |
|
|
| `color` | [`string`](/docs/kcl-std/types/std-types-string) | Color of the new material, a hex string like '#ff0000'. | Yes |
|
|
| `metalness` | [`number(_)`](/docs/kcl-std/types/std-types-number) | Metalness of the new material, a percentage like 95.7. | No |
|
|
| `roughness` | [`number(_)`](/docs/kcl-std/types/std-types-number) | Roughness of the new material, a percentage like 95.7. | No |
|
|
|
|
### Returns
|
|
|
|
[`[Solid; 1+]`](/docs/kcl-std/types/std-types-Solid) or [`ImportedGeometry`](/docs/kcl-std/types/std-types-ImportedGeometry)
|
|
|
|
|
|
### Examples
|
|
|
|
```kcl
|
|
// Add color to an extruded solid.
|
|
exampleSketch = startSketchOn(XZ)
|
|
|> startProfile(at = [0, 0])
|
|
|> line(endAbsolute = [10, 0])
|
|
|> line(endAbsolute = [0, 10])
|
|
|> line(endAbsolute = [-10, 0])
|
|
|> close()
|
|
|
|
example = extrude(exampleSketch, length = 5)
|
|
// There are other options besides 'color', but they're optional.
|
|
|> appearance(color = '#ff0000')
|
|
|
|
```
|
|
|
|
|
|
|

|
|
|
