I cleand up the definition. So maybe it helps if someone has a look at it.
The aim is as you can see in the image below to map the intersection points of the wavy surfaces onto the unrolled lines. In one case I got it to work but in the other case not. The main problem is really the shutter component, because it is working different and i don´t know why. Maybe someone has an other idea.
Any help is really much appreciated
The problem you face is that the curve taken from the Brep Explode component has a domain going from -15 to 0 and that the original curve that you got the t values from is 0 to 15. I don't know if what I've done here fixes it but it shows the shatter component working on the curve.
