API Reference > geometry-core > Solid > SweepContour SweepContour Class Sweepable contour with Transform for local to world interaction. The surface/solid classes LinearSweep, RotationalSweep, RuledSweep use this for their swept contours. Methods Name Description announceFacets(announce: (facets: IndexedPolyface) => void, options: undefined | StrokeOptions): void Emit facets to a function buildFacets(options: undefined | StrokeOptions): void build the (cached) internal facets. clone(): SweepContour Return a deep clone. cloneTransformed(transform: Transform): undefined | SweepContour Return a transformed clone. emitFacets(builder: PolyfaceBuilder, reverse: boolean, transform?: Transform): void Emit facets to a builder. getCurves(): CurveCollection Return (Reference to) the curves isAlmostEqual(other: any): boolean Test for near equality of cures and local frame. purgeFacets(): void delete existing facets. sweepToUnionOfConvexClipPlaneSets(sweepVector?: Vector3d, cap0: boolean = false, cap1: boolean = false): undefined | UnionOfConvexClipPlaneSets Triangulate the region. tryTransformInPlace(transform: Transform): boolean Apply transform to the curves, axis. createForLinearSweep(contour: CurveCollection, defaultNormal?: Vector3d): undefined | SweepContour Static Create for linear sweep. createForPolygon(points: MultiLineStringDataVariant, defaultNormal?: Vector3d): undefined | SweepContour Static Create for linear sweep. createForRotation(contour: CurveCollection, axis: Ray3d): undefined | SweepContour Static Create for rotational sweep. Properties Name Type Description axis undefined | Ray3d Axis used only in rotational case. curves CurveCollection The underlying curve collection, in its world coordinates position. localToWorld Transform coordinate frame that in which the curves are all in the xy plane. xyStrokes Accessor ReadOnly undefined | AnyCurve Defined in solid/SweepContour.ts Line 35 Last Updated: 11 June, 2024
