| `symmetric` | [`bool`](/docs/kcl/types/bool) | If true, the extrusion will happen symmetrically around the sketch. Otherwise, the extrusion will happen on only one side of the sketch. | No |
| `bidirectionalAngle` | `number(deg)` | If specified, will also revolve in the opposite direction to 'angle' to the specified angle. If 'symmetric' is true, this value is ignored. | No |
| `tagStart` | [`tag`](/docs/kcl/types/tag) | A named tag for the face at the start of the revolve, i.e. the original sketch. | No |
| `tagEnd` | [`tag`](/docs/kcl/types/tag) | A named tag for the face at the end of the revolve. | No |
### Returns
[`Solid`](/docs/kcl/types/Solid)
### Examples
```js
part001 = startSketchOn(XY)
|> startProfileAt([4, 12], %)
|> line(end = [2, 0])
|> line(end = [0, -6])
|> line(end = [4, -6])
|> line(end = [0, -6])
|> line(end = [-3.75, -4.5])
|> line(end = [0, -5.5])
|> line(end = [-2, 0])
|> close()
|> revolve(axis = Y) // default angle is 360
