extrudeTwist	Function in std::sketch	Works just like the `extrude` command, but also twists the sketch around some center point while it's extruding.	manual

Works just like the extrude command, but also twists the sketch around some center point while it's extruding.

extrudeTwist(
  @sketches: [Sketch; 1+],
  angle: number(Angle),
  length: number(Length),
  angleStep?: number(Angle),
  tagStart?: tag,
  tagEnd?: tag,
  center?: Point2d,
): [Solid; 1+]

You can provide more than one sketch to extrude, and they will all be extruded in the same direction with the same twist.

Arguments

Name	Type	Description	Required
sketches	[Sketch; 1+]	Which sketch or sketches should be extruded.	Yes
angle	number(Angle)	The total angle that the sketch will be twisted around	Yes
length	number(Length)	How far to extrude the given sketches.	Yes
angleStep	number(Angle)	The size of each intermediate angle as the sketch twists around. Must be between 4 and 90 degrees. Defaults to 15 degrees.	No
tagStart	tag	A named tag for the face at the start of the extrusion, i.e. the original sketch.	No
tagEnd	tag	A named tag for the face at the end of the extrusion, i.e. the new face created by extruding the original sketch.	No
center	Point2d	The center around which the sketch will be twisted. Relative to the sketch's center. If not given, defaults to 0,0 i.e. the sketch's center.	No

Returns

[Solid; 1+]
