can you have a look at my result?
i have tried following yours and other advice, and i think yours is the only one giving me close results...but still getting a mistake somewhere

thanks

hi javier

below a simple sort.... you have to choose the points and bake the pline step by step
for changing the axis just switch between x,y,z
to do that automated we had to write a little vb script

hi javier

you have to right click on your point component and flatten the input than it should be ok (it is to flatten the data structure)

no you didn't get me !!!
so flatten in grasshopper means to loose the information on which line the intersection point had been (it's like a history so turning off the history) otherwise the following components won't be working in the way they should

i don't know if you saw the results, but i can't get it to work.
maybe i shouldn't try to learn this stuff by myself, i am getting mad

thanks man

hi javier

so if you send me your 3dm file also i can take a much better view on your problem
don't get frustrated it's a little bit hard in the beginning but after that it is a lot of fun

what i am working is with just a couple of curves.
i want this, laterto work with detailed curves from topography.
i know how to do it, by hand, it's just i want this done by a script or grasshopper to get more precission.

i send you the ghx and a 3dm with 4 curves.

this is to work on Y direction
then i guess i am ready to make it work on the other by myself

thanks thanks!

send you the other way i was exploring (iso to terrainB.ghx)

thanks, i see it now.
the only thing i don't know how to get all the results.
i mean, i see i can set the index and gives me diferent results.
but can't understand how to get all the results by once.
you already got it, didn't you?

thanks

next week i will start little by little with all the theory, and not jumpso straight to the practice!

hi javier
so currently without vb scripting it is not possible to pack all the stuff inside a loop so you have to bake every polyline and then you have all of them so shift the index bake the line and again until you have all of them
.... so only vb would help to automate it completely
