Hi Brian,

it seems that the DetA sometimes isn't zero for linesegments. So, caused by a division near zero, it produces very high values for the centerpoint. That crashes the factories, esspecially for interpcurve. I've try to fix it by limitation of a maximum radius of 10000 and a minimum radius for curvature calculation of 0.002 (csp returns for lines p1 - that leads to a radius of zero -> divide by zero - > high values for the factories). Further more the changes supresses the generation of degenerated lines (startpoint equals endpoint). I've marked the changes in the script with //############. Also I made some test with the results with another tool. You may have a look at the pictures. It seem that other tools seperates connected curves for the analyse. So the precission at the connection points, especially with lines, isn't good.

Have a nice day!

Kind regards
Karsten
