std::sketch::mirror2d	Mirror a sketch.	manual

Mirror a sketch.

Only works on unclosed sketches for now.

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

mirror2d(@sketches: [Sketch; 1+], axis: Axis2d | Edge): Sketch

Arguments

Name	Type	Description	Required
sketches	[Sketch; 1+]	The sketch or sketches to be reflected.	Yes
axis	`Axis2d	Edge`	The axis to reflect around.

Returns

Sketch

Examples

// Mirror an un-closed sketch across the Y axis.
sketch001 = startSketchOn(XZ)
    |> startProfileAt([0, 10], %)
    |> line(end = [15, 0])
    |> line(end = [-7, -3])
    |> line(end = [9, -1])
    |> line(end = [-8, -5])
    |> line(end = [9, -3])
    |> line(end = [-8, -3])
    |> line(end = [9, -1])
    |> line(end = [-19, -0])
    |> mirror2d(axis = Y)
