hey guys,
grasshopper noob here. i need to create a lot of lines from 2 point sets and then measure them.
unfortunatly the line component connects all my points, which leads to thousand of lines, and not just the wanted pairs.
i remember, about 10 years ago, we used the cull component to control that, but i have no clue which pattern i have to use here.
could you guys pls help me out?
cheers,
Ben
This is usually related to the datatree structure of your input, and the usual solution is to use a combination of grafting/flattening + merging operations, but to give you a precise indication we would need to see the actual file
Well … without data here’s a naive answer: graft your Lists and cross fingers
hey, thx, here is an example file including the gh-definition.
at first i tried to create lines from the division points of the bottom curve and the intersection points of the top curve and measure them.
then i tried to measure just the distance between the points.
line-measure.3dm (46.4 KB)
line-measure.gh (6.4 KB)
That’s elementary my Dear Watson (10 years eh? ).
Since the Ccx thingy outputs a Tree
The Line/Dist/Tag things shoud somehow follow (Graft, that is: resulting 1:1 pt A, ptB for doing the lines or computing distances, placing Tags etc etc).
Tip: spend some time on DataTrees (kinda a Dictionary of Lists). 99.99999% of the issues that people have are because they think that understand what a DT is.
NOTE: a DT is NOT a List of List of …
hey Pfotiad0, yeah, must be 10 years or longer. 
thank you, i know there is this wonderful primer from David, but usually I model everything per hand (really).
I should definitly give it a try.
works like a charme! =P
You are a wise man. Stay away from computers (I hate’m) and be a happy bunny.
But IF you want to walk the walk … here’s the controvercy of the day: it’s by far easier to handle DT’s (and anything else) via code than using components. But is it easy to learn coding? That’s the 1M question, he he.
best
haha, no, i meant without code or grasshopper, drawing with mouse and hand.
i never will learn coding, maybe using grasshopper a little bit better, because its so super handy. i saw a guy doing some impressing stuff in f#, this is not my world. i am a shaper, designer, curvy thingy making guy, no numbers, just colors and form.
have fun,
B
