shell

Remove volume from a 3-dimensional shape such that a wall of the provided thickness remains, taking volume starting at the provided face, leaving it open in that direction.

shell(
  solids: [Solid],
  thickness: number,
  faces: [FaceTag],
): [Solid]

Arguments

Name	Type	Description	Required
`solids`	`[Solid]`	Which solid (or solids) to shell out	Yes
`thickness`	`number`	The thickness of the shell	Yes
`faces`	`[FaceTag]`	The faces you want removed	Yes

Returns

[Solid]

Examples

// Remove the end face for the extrusion.
firstSketch = startSketchOn(XY)
  |> startProfileAt([-12, 12], %)
  |> line(end = [24, 0])
  |> line(end = [0, -24])
  |> line(end = [-24, 0])
  |> close()
  |> extrude(length = 6)

// Remove the end face for the extrusion.
shell(firstSketch, faces = [END], thickness = 0.25)

Rendered example of shell 0

// Remove the start face for the extrusion.
firstSketch = startSketchOn(-XZ)
  |> startProfileAt([-12, 12], %)
  |> line(end = [24, 0])
  |> line(end = [0, -24])
  |> line(end = [-24, 0])
  |> close()
  |> extrude(length = 6)

// Remove the start face for the extrusion.
shell(firstSketch, faces = [START], thickness = 0.25)

Rendered example of shell 1

// Remove a tagged face and the end face for the extrusion.
firstSketch = startSketchOn(XY)
  |> startProfileAt([-12, 12], %)
  |> line(end = [24, 0])
  |> line(end = [0, -24])
  |> line(end = [-24, 0], tag = $myTag)
  |> close()
  |> extrude(length = 6)

// Remove a tagged face for the extrusion.
shell(firstSketch, faces = [myTag], thickness = 0.25)

Rendered example of shell 2

// Remove multiple faces at once.
firstSketch = startSketchOn(XY)
  |> startProfileAt([-12, 12], %)
  |> line(end = [24, 0])
  |> line(end = [0, -24])
  |> line(end = [-24, 0], tag = $myTag)
  |> close()
  |> extrude(length = 6)

// Remove a tagged face and the end face for the extrusion.

Rendered example of shell 3

// Shell a sketch on face.

  |> circle(center = [size / 2, -size / 2], radius = 25)
  |> extrude(length = 50)

// We put "case" in the shell function to shell the entire object.

Rendered example of shell 4

// Shell a sketch on face object on the end face.
size = 100

  |> extrude(length = 50)

// We put "thing1" in the shell function to shell the end face of the object.
shell(thing1, faces = [END], thickness = 5)

Rendered example of shell 5

// Shell sketched on face objects on the end face, include all sketches to shell
// the entire object.
