title: "revolve"

excerpt: "Rotate a sketch around some provided axis, creating a solid from its extent."

|
|
|
|
Rotate a sketch around some provided axis, creating a solid from its extent.
|
|
|
|
This, like extrude, is able to create a 3-dimensional solid from a 2-dimensional sketch. However, unlike extrude, this creates a solid by using the extent of the sketch as its revolved around an axis rather than using the extent of the sketch linearly translated through a third dimension.
|
|
|
|
Revolve occurs around a local sketch axis rather than a global axis.
|
|
|
|
You can provide more than one sketch to revolve, and they will all be revolved around the same axis.
|
|
|
|
```js
|
|
revolve(
|
|
data: RevolveData,
|
|
sketches: [Sketch],
|
|
): [Solid]
|
|
```
|
|
|
|
|
|
