Some wrong Control points



i tried to read a 3DM File (from Rhino v.5.1.30129.1756, 29.01.2013), but one Row of the Control point matrix is wrong.

I used the OpenNURBS Toolkit (example_read) from version 20110202 and 20121024, but its the same problem.

But in Rhino 5 and the Step conversion the Control points are correct.

Here is a Screenshot from our System with the Step-File (red) and the 3DM-File (green).

Best regards
