RuledSweep Class

A ruled sweep (surface) is a collection of 2 or more contours.

  • All contours must have identical number and type of geometry: (paths, loops, parity regions, lines, arcs, other curves).

Methods

Name Description
clone(): RuledSweep Return a deep clone.  
cloneContours(): CurveCollection[] Return clones of the sweep contours, each as a CurveCollection.  
cloneSweepContours(): SweepContour[] Return clones of the sweep contours.  
cloneTransformed(transform: Transform): undefined | RuledSweep Return a transformed clone.  
constantVSection(vFraction: number): undefined | CurveCollection Return the section curves at a fraction of the sweep.  
dispatchToGeometryHandler(handler: GeometryHandler): any Dispatch to strongly typed handler.handleRuledSweep(this).  
extendRange(rangeToExtend: Range3d, transform?: Transform): void Pass each contour to extendRange.  
getConstructiveFrame(): undefined | Transform Return a coordinate frame (right handed unit vectors)  
isAlmostEqual(other: GeometryQuery): boolean Test for near equality of two RuledSweeps.  
isSameGeometryClass(other: any): boolean Test if other is an instance of a RuledSweep.  
sweepContoursRef(): SweepContour[] Return a reference to the array of SweepContour.  
tryTransformInPlace(transform: Transform): boolean Transform all contours in place.  
create(contours: AnyCurve[], capped: boolean): undefined | RuledSweep Static Create a ruled sweep from an array of contours.  
mutatePartners(collectionA: CurveCollection, collectionB: CurveCollection, primitiveMutator: CurvePrimitiveMutator): undefined | CurveCollection Static Construct a CurveCollection with the same structure as collectionA and collectionB, with primitives constructed  

Inherited methods

Name Inherited from Description
range(transform?: Transform, result?: Range3d): Range3d Inherited SolidPrimitive Return the range of the entire GeometryQuery tree.
tryTranslateInPlace(dx: number, dy: number = 0.0, dz: number = 0.0): boolean Inherited SolidPrimitive Try to move the geometry by dx,dy,dz.
areAlmostEqual(a: GeometryQuery, b: GeometryQuery): boolean Static Inherited SolidPrimitive Apply instance method isAlmostEqual if both are defined.
