sweep

Extrude a sketch along a path.

This, like extrude, is able to create a 3-dimensional solid from a 2-dimensional sketch. However, unlike extrude, this creates a solid by using the extent of the sketch as its path. This is useful for creating more complex shapes that can't be created with a simple extrusion.

You can provide more than one sketch to sweep, and they will all be swept along the same path.

sweep(
  sketches: [Sketch],
  path: SweepPath,
  sectional?: bool,
  tolerance?: number,
  tagStart?: TagDeclarator,
  tagEnd?: TagDeclarator,
): [Solid]

Arguments

NameTypeDescriptionRequired
sketches[Sketch]The sketch or set of sketches that should be swept in spaceYes
pathSweepPathThe path to sweep the sketch alongYes
sectionalboolIf true, the sweep will be broken up into sub-sweeps (extrusions, revolves, sweeps) based on the trajectory path components.No
tolerancenumberTolerance for this operationNo
tagStartTagDeclaratorA named tag for the face at the start of the sweep, i.e. the original sketchNo
tagEndTagDeclaratorA named tag for the face at the end of the sweepNo

Returns

[Solid]

Examples

// Create a pipe using a sweep.

// Create a path for the sweep.
sweepPath = startSketchOn(XZ)
  |> startProfileAt([0.05, 0.05], %)
  |> line(end = [0, 7])
  |> tangentialArc({ offset = 90, radius = 5 }, %)
  |> line(end = [-3, 0])
  |> tangentialArc({ offset = -90, radius = 5 }, %)
  |> line(end = [0, 7])

// Create a hole for the pipe.
pipeHole = startSketchOn(XY)
  |> circle(center = [0, 0], radius = 1.5)

sweepSketch = startSketchOn(XY)
  |> circle(center = [0, 0], radius = 2)
  |> hole(pipeHole, %)
  |> sweep(path = sweepPath)

Rendered example of sweep 0

// Create a spring by sweeping around a helix path.

// Create a helix around the Z axis.
helixPath = helix(
  angleStart = 0,
  ccw = true,
  revolutions = 4,
  length = 10,
  radius = 5,
  axis = 'Z',
)

// Create a spring by sweeping around the helix path.
springSketch = startSketchOn(YZ)
  |> circle(center = [0, 0], radius = 1)
  |> sweep(path = helixPath)

// Sweep two sketches along the same path.

  |> angledLine([0, 73.47], %, $rectangleSegmentA001)

  |> close()

circleSketch = circle(sketch001, center = [200, -30.29], radius = 32.63)

  |> yLine(length = 231.81)
  |> tangentialArc({ radius = 80, offset = -90 }, %)
