New Ifc4x3 spiral and polynomial curves had an infinite loop issue when trying to get theie dimensions.
Spirals are 2D in nature and polynomial are evaluated according to their position.
Gradient and SegmentedReference curves are 3D despite their 2D segments, they are not merely composition of their "Segments" as Composite curves. The segments provide other dimension of info about the curve; curve height(Z coordinate) in case of gradient curves and super-elevation and tilt/cant orientation in case of segmented reference curves.
