As mentionend in the title:
Extending this curve with _extendCrvOnSrf looks like the boundary / boarder / outer Loop of the surface / Brep is not respected - the unterlaying surface seams to effect the new length.
maybe this is because the curve is very close to an isocurve ?
if Surfaceboarder and Trim-Curve are very close to each other, so you can not see it immediately as in this example, this might be an very annoying source of errors…
thanks for having a look at this. kind regards -tom
