Sven and Matthew, I think I have got a solution to avoid the infinite loop but I don't know why:
NEVER modify the first three 0's and the last three 1's points, they have to be 0's and 1's.
in the democurve script, the last try of the demonstration intend to touch the third zero (which will cause the inifinite loop) so in the democurve.m file the code:
% @forbidden code start
crv.knots(1)=0.1;
crv.knots(2)=0.1;
crv.knots(3)=0.1;
crv.knots(end-2)=0.1;
crv.knots(end-1)=0.1;
crv.knots(end)=0.1;
@ forbidden code end
are all forbidden code lines,

crv.knots(4)=0.1;
crv.knots(5)=0.1;
crv.knots(6)=0.1;
... ...
crv.knots(end-5)=0.1;
crv.knots(end-4)=0.1;
crv.knots(end-3)=0.1;
 are the permissive code lines. Am I clear ? ? :-]

Seemed to run just fine, but ANSYS can't read it. NrbsSrf2IGES produces IGES that can be read.

I'm trying to convert point cloud data (from a Kinect) to iges to import into Rhino (and then to Solidworks).

I put my data in to X, Y, and Z columns and the function appears to run successfully. However, when I try to import this file into Rhino it says: "Rhino found nothing to import from this IGES file.
This happens when an IGES file has no valid independent geometry."

Any thoughts on what is going wrong?
