Detailed Description

Class for nesting computation The purpose of this class is to compute placement of several parts into a sheet.

// nesting object
let nesting = new GO2SNesting()
 
// add a rectangle as nesting sheet
let sheet = new GO2SRectangle(new GO2SXYZ, new GO2SXYZ(300, 200, 0))
sheet.SetColor(0x0000FF)
nesting.AddSheet(sheet, 1) // keep 1mm free border
 
// create a solid shape to be nested
let solid = GO2SSolidCreate.Cuboid(new GO2SXYZ(), new GO2SXYZ(30, 0, 0), new GO2SXYZ(20, 50, 0), 10)
nesting.AddPart(solid, GO2SNestingOrientation.Free, 12, 1)
 
// create a mesh shape to be nested
let mesh = GO2SMeshCreate.Cuboid(new GO2SXYZ(), new GO2SXYZ(40, 0, 0), new GO2SXYZ(10, 60, 0), 10)
nesting.AddPart(mesh, GO2SNestingOrientation.Free, 8, 1)
 
// create a wireframe shape to be nested
let ellipse = GO2SEllipseCreate.From3Points(new GO2SXYZ(), new GO2SXYZ(20, 0, 0), new GO2SXYZ(0, 10, 0))
nesting.AddPart(ellipse, GO2SNestingOrientation.Free, 8, 1)
 
// create a profile shape to be nested
let ply = GO2SPolygonCreate.From2Points(new GO2SXYZ(), new GO2SXYZ(25, 0, 0), 8, true)
let profile = GO2SProfileCreate.FromMultiGeom(ply)
nesting.AddPart(profile, GO2SNestingOrientation.Free, 6, 1)

AddPart()

GO2SEnum::GO2SError GO2SNesting::AddPart	(	GO2SGeometry	geom,
		GO2SEnum::GO2SNestingOrientation	orientation,
		Number	nbParts,
		Number	part_dist )

Add a part to be nested in the sheet.

Remarks

wireframe geometry must be closed, planar (Z direction). For volume geometry, silhouette in Z direction will be considered

Returns

GO2SError.success (0) if successful, see GO2SError otherwise

Version

2026

Parameters

[in]	geom	Geometry object to be nested
[in]	orientation	Orientation constraint for the nesting
[in]	nbParts	Number of parts to be nested
[in]	part_dist	Distance between parts

AddSheet()

GO2SEnum::GO2SError GO2SNesting::AddSheet	(	GO2SGeometry	sheet,
		Number	border_dist )

Create a nesting sheet from a geometry.

Remarks

wireframe geometry must be closed, planar (Z direction). For volume geometry, silhouette in Z direction will be considered

Returns

GO2SError.success (0) if successful, see GO2SError otherwise

Version

Parameters

[in]	sheet	geometry representing the sheet
[in]	border_dist	Distance between the sheet border and the parts

Apply()

Array< GO2SGeometry > GO2SNesting::Apply

(

)

Apply the computed positioning of the parts

Returns

All the nested geometries

Compute()

GetNbPartsNested()

Number GO2SNesting::GetNbPartsNested	(	GO2SGeometry	solid,
		Boolean	sym )
