revolveFunction in std::sketch

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

revolve(
  @sketches: [Sketch; 1+],
  axis: Axis2d | Edge,
  angle?: number(Angle),
  tolerance?: number(Length),
  symmetric?: bool,
  bidirectionalAngle?: number(Angle),
  tagStart?: tag,
  tagEnd?: tag,
): [Solid; 1+]

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.

Arguments

Name	Type	Description	Required
`sketches`	`[Sketch; 1+]`	The sketch or set of sketches that should be revolved	Yes
`axis`	`Axis2d` or `Edge`	Axis of revolution.	Yes
`angle`	`number(Angle)`	Angle to revolve (in degrees). Default is 360.	No
`tolerance`	`number(Length)`	Tolerance for the revolve operation.	No
`symmetric`	`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(Angle)`	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`	A named tag for the face at the start of the revolve, i.e. the original sketch.	No
`tagEnd`	`tag`	A named tag for the face at the end of the revolve.	No

Returns

[Solid; 1+]
