Gavin,

I am able to create a CurveString from all of my test cases. Using the same
collection to CreateRing fails.

The following is the Text. 

CURVESTRING (-9.5014975482 57.7478735875 (LINESTRINGSEGMENT (19.6461752358 
74.8512708505), CIRCULARARCSEGMENT (22.7050279997 77.8811849788,
14.5568991154 
91.0301601151), LINESTRINGSEGMENT (-25.6946492068 67.4552071463), 
CIRCULARARCSEGMENT (-29.4810738917 63.7107055978, -9.50149754820001 
57.7478735875)))

CURVESTRING (8.47147613 18.3352938846 (CIRCULARARCSEGMENT (11.6905692648 
19.1572633102, 10.8858122466 31.3151724971), CIRCULARARCSEGMENT
(7.5864632445 
31.7056728291, 8.47147613 18.3352938846)))

CURVESTRING (61.9192385091 10.2621902206 (LINESTRINGSEGMENT (55.2181323514 
1.4697652754), LINESTRINGSEGMENT (70.4772774943 4.8576720598), 
CIRCULARARCSEGMENT (67.476657509 8.4619402206, 61.9192385091
10.2621902206)))

Does this help at all?

Hello again, Dennis.  That comparison of Point2D objects may call code that
includes internal distance calculations and comparisons with tolerances. 
The definitive test would be to check the X and Y ordinates directly.

Gavin
