Mirror a sketch.

Only works on unclosed sketches for now.

Mirror occurs around a local sketch axis rather than a global axis.

mirror2d(
  data: Mirror2dData,
  sketches: [Sketch],
): [Sketch]

Arguments

Name	Type	Description	Required
data	Mirror2dData	Data for a mirror.	Yes
sketches	[Sketch]		Yes

Returns

[Sketch]
