sweep	Extrude a sketch along a path.	manual

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.

sweep(
  sketch: Sketch,
  path: SweepPath,
  sectional?: bool,
  tolerance?: number,
): Solid

Arguments

Name	Type	Description	Required
sketch	Sketch	The sketch that should be swept in space	Yes
path	SweepPath	The path to sweep the sketch along	Yes
sectional	bool	If true, the sweep will be broken up into sub-sweeps (extrusions, revolves, sweeps) based on the trajectory path components.	No
tolerance	number	Tolerance for this operation	No

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)

// 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)
