loft

Create a 3D surface or solid by interpolating between two or more sketches.

The sketches need to closed and on the same plane.

loft(sketches: [Sketch], data?: LoftData) -> Solid

Arguments

Name	Type	Description	Required
`sketches`	`[Sketch]`		Yes
`data`	`LoftData`	Data for a loft.	No

Returns

Solid - An solid is a collection of extrude surfaces.

Examples

// Loft a square and a triangle.
squareSketch = startSketchOn('XY')
  |> startProfileAt([-100, 200], %)
  |> line([200, 0], %)
  |> line([0, -200], %)
  |> line([-200, 0], %)
  |> lineTo([profileStartX(%), profileStartY(%)], %)
  |> close(%)

triangleSketch = startSketchOn(offsetPlane('XY', 75))
  |> startProfileAt([0, 125], %)
  |> line([-15, -30], %)
  |> line([30, 0], %)
  |> lineTo([profileStartX(%), profileStartY(%)], %)
  |> close(%)
