    Interface Drawing

    Immutable wrapper around a 2D shape (Blueprint, CompoundBlueprint, or Blueprints).

    A Drawing can be transformed (translate, rotate, scale, mirror), combined with Boolean operations (cut, fuse, intersect), filleted/chamfered, serialized, and ultimately projected onto a 3D plane via sketchOnPlane.

    const profile = drawRectangle(40, 20)
      .fillet(3)
      .cut(drawCircle(5).translate(10, 0));
    const sketch = profile.sketchOnPlane("XY");
    interface Drawing {
        get blueprint(): Blueprint;
        get boundingBox(): BoundingBox2d;
        get repr(): string;
        approximate(
            target: "svg" | "arcs",
            options?: ApproximationOptions,
        ): Drawing;
        chamfer(
            radius: number,
            filter?: (c: CornerFinderFn) => CornerFinderFn,
        ): Drawing;
        clone(): Drawing;
        cut(other: Drawing): Drawing;
        fillet(
            radius: number,
            filter?: (c: CornerFinderFn) => CornerFinderFn,
        ): Drawing;
        fuse(other: Drawing): Drawing;
        intersect(other: Drawing): Drawing;
        mirror(
            centerOrDirection: Point2D,
            origin?: Point2D,
            mode?: "plane" | "center",
        ): Drawing;
        offset(distance: number, offsetConfig?: Offset2DConfig): Drawing;
        punchHole(
            shape: AnyShape<Dimension>,
            faceFinder: SingleFace,
            options?: { draftAngle?: number; height?: number; origin?: PointInput },
        ): AnyShape<Dimension>;

      Returns string

    • Return the SVG <path> d attribute strings for this drawing.

      Returns string[] | string[][]

    • Return the SVG viewBox attribute string for this drawing.

      Parameters
