std::sketch::patternCircular2d	Repeat a 2-dimensional sketch some number of times along a partial or complete circle some specified number of times. Each object may additionally be rotated along the circle, ensuring orentation of the solid with respect to the center of the circle is maintained.	manual

Repeat a 2-dimensional sketch some number of times along a partial or complete circle some specified number of times. Each object may additionally be rotated along the circle, ensuring orentation of the solid with respect to the center of the circle is maintained.

patternCircular2d(
  @sketchSet: [Sketch],
  instances: number,
  center: Point2d,
  arcDegrees: number,
  rotateDuplicates: bool,
  useOriginal?: bool,
): [Sketch]

Arguments

Name	Type	Description	Required
sketchSet	[Sketch]	Which sketch(es) to pattern	Yes
instances	number	The number of total instances. Must be greater than or equal to 1. This includes the original entity. For example, if instances is 2, there will be two copies -- the original, and one new copy. If instances is 1, this has no effect.	Yes
center	Point2d	The center about which to make the pattern. This is a 2D vector.	Yes
arcDegrees	number	The arc angle (in degrees) to place the repetitions. Must be greater than 0.	Yes
rotateDuplicates	bool	Whether or not to rotate the duplicates as they are copied.	Yes
useOriginal	bool	If the target was sketched on an extrusion, setting this will use the original sketch as the target, not the entire joined solid. Defaults to false.	No

Returns

[Sketch]
