appendToArcInPlace MethodStatic

If arcB is a continuation of arcA, extend arcA (in place) to include the range of arcB

  • This only succeeds if the two arcs are part of identical complete arcs and end of arcA matches the beginning of arcB.

appendToArcInPlace(arcA: Arc3d, arcB: Arc3d, allowReverse: boolean = false, tolerance: number = Geometry.smallMetricDistance): boolean

@returns whether arcA was modified.

Parameter Type Description
arcA Arc3d first arc, modified in place.
arcB Arc3d second arc, unmodified.
allowReverse boolean  
tolerance number optional coordinate tolerance for point equality (default is Geometry.smallMetricDistance).

Returns - boolean

whether arcA was modified.
