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(data: ShellData, solid_set: SolidSet) -> SolidSet

Arguments

Name	Type	Description	Required
`data`	`ShellData`	Data for shells.	Yes
`solid_set`	`SolidSet`	A solid or a group of solids.	Yes

Returns

SolidSet - A solid or a group of solids.

Examples

// Remove the end face for the extrusion.

  |> startProfileAt([-12, 12], %)
  |> line([24, 0], %)
  |> line([0, -24], %)

// Remove the end face for the extrusion.
