maxGap(): number CurveCollection return the max gap between adjacent primitives in Path and Loop collections.
projectedParameterRange(ray: Ray3d | Vector3d, lowHigh?: Range1d): undefined | Range1d CurveCollection Project instance geometry (via dispatch) onto the given ray, and return the extreme fractional parameters of projection.
range(transform?: Transform, result?: Range3d): Range3d CurveCollection return the range of the entire (tree) GeometryQuery
sumLengths(): number CurveCollection Return the sum of the lengths of all contained curves.
tryTransformInPlace(transform: Transform): boolean CurveCollection Apply transform recursively to children
tryTranslateInPlace(dx: number, dy: number = 0.0, dz: number = 0.0): boolean CurveCollection try to move the geometry by dx,dy,dz
areAlmostEqual(a: undefined | GeometryQuery, b: undefined | GeometryQuery): boolean Static CurveCollection apply instance method isAlmostEqual if both are defined.
createCurveLocationDetailOnAnyCurvePrimitive(source: undefined | GeometryQuery, fraction: number = 0.5): undefined | CurveLocationDetail Static CurveCollection * Find any curve primitive in the source.

Inherited properties

Name Type Inherited from Description
geometryCategory Readonly "curveCollection" CurveCollection String name for schema properties
isAnyRegionType Accessor ReadOnly boolean CurveCollection Return true for planar region types:
* Loop
* ParityRegion
* UnionRegion
isClosedPath Accessor ReadOnly boolean CurveCollection Return true for a single-loop planar region type, i.e. Loop.
* This is _not- a test for physical closure of a Path
isInner boolean CurveCollection Flag for inner loop status.
isOpenPath Accessor ReadOnly boolean CurveCollection Return true for a Path, i.e. a chain of curves joined head-to-tail
