Extend curve?

What should i do to extend the vertical curves to the Bottom of the Surface ? I would like the lines to follow the form of the surface if possible.

Is that what you mean?

Thank you both of you ! I now have a long term algorithm to subdivide my surface into panels ! @leopoldomonzani How did you come with your solution ? Did you do something like that in the past ? Or was it pure logic problem solving mindset ?

It seemed like a good solution to me.

Thanks. Do you know how to cull the first set and the last one ? I would like to keep the original BRep edge as guiding curve. I tried something here, but when merging, nothing happens ?

Do you mean to select the curves at the end of the surface?
You can proceed in two ways: see image.

I mean to keep the curves at the end of the surface from the original brep and to remove the curves at the end of the surface you worked on. So basically 1 and 10 should be removed.

Oh well, maybe I understand.

Yes, i knew i would have to cull index all at the same time with one panel and not two Cull Indexes. But when i wrote 1 and 0 into a panel it didn’t work. Why is your panel different ? ( i mean the yellow panel ). Did you use the brackets, is this the difference ?

Ok i found it, i had to use multidata ! Thanks.

Could you explain how you found the numbers for the parameters at evaluate curve ?

There is no explanation for finding the numbers for dividing the curve, change the parameters until you find a satisfactory solution.
Maybe your Panel isn’t working because you didn’t deselect the Multiline Data option.
To remove/select at the bottom of the list you have to use -1, - 2, - 3……
