LinearSweep Class

A LinearSweep is a SolidPrimitive defined by

  • A set of curves (any Loop, Path, or parityRegion)
  • A sweep vector If the object is "capped", the curves must be planar.

Extends

Methods

Name Description
constructor(capped: boolean): LinearSweep Protected    
clone(): LinearSweep Return a deep clone  
cloneSweepVector(): Vector3d return a clone of the sweep vector  
cloneTransformed(transform: Transform): LinearSweep Return a transformed clone  
constantVSection(vFraction: number): CurveCollection | undefined Return the curves at a fraction along the sweep direction.  
dispatchToGeometryHandler(handler: GeometryHandler): any Invoke strongly typed handler.handleLinearSweep(this)  
extendRange(rangeToExtend: Range3d, transform?: Transform): void Extend rangeToExtend to include this geometry.  
getConstructiveFrame(): Transform | undefined Return a coordinate frame (right handed unit vectors)
origin on base contour
x, y directions from base contour.
 
getCurvesRef(): CurveCollection get a reference to the swept curves  
getSweepContourRef(): SweepContour Get a reference to the SweepContour carrying the plane of the curves  
isAlmostEqual(other: GeometryQuery): boolean Test for near-equality of coordinates in other  
isSameGeometryClass(other: any): boolean Test if other is also an instance of LinearSweep  
tryTransformInPlace(transform: Transform): boolean apply a transform to the curves and sweep vector  
create(contour: CurveCollection, direction: Vector3d, capped: boolean): LinearSweep | undefined Static Create a sweep of a starting contour.  
createZSweep(xyPoints: XAndY[], z: number, zSweep: number, capped: boolean): LinearSweep | undefined Static Create a z-direction sweep of the polyline or polygon given as xy linestring values.
