subtract2d(
  @sketch: Sketch,
  tool: [Sketch],
): Sketch

Arguments

Name	Type	Description	Required
sketch	Sketch	Which sketch should this path be added to?	Yes
tool	[Sketch]	The shape(s) which should be cut out of the sketch.	Yes

Returns

Sketch - A sketch is a collection of paths.

Examples

exampleSketch = startSketchOn(XY)
  |> startProfile(at = [0, 0])
  |> line(end = [0, 5])
  |> line(end = [5, 0])
  |> line(end = [0, -5])
  |> close()
  |> subtract2d(tool = circle(center = [1, 1], radius = .25))
  |> subtract2d(tool = circle(center = [1, 4], radius = .25))

example = extrude(exampleSketch, length = 1)

fn squareHoleSketch() {
  squareSketch = startSketchOn(-XZ)
    |> startProfile(at = [-1, -1])
    |> line(end = [2, 0])
    |> line(end = [0, 2])
    |> line(end = [-2, 0])
    |> close()
