Hi!
I am using Grasshopper after a long time without using it.
I have a very strange problem, maybe this is evident but i don’t know how to solve it: what i would like to do, is, from each point that divides my curve, is drawing the tangent vector to the divided curve, and from each tangent vector, drawing a segment with two points, in order to have the direction of each tangent and the segment line from this. I really don’t know how to do this, we have at the command “Divide Curve”, in the output, “T”, that is for tangent vector, but, i tried from this output to use the commande “construct point”, or "deconstruct point’, too, i tried to connect at this output the command “Vector Display Ex”, but i see no vectors, and i don’t know why, could you please help me?
Thanks so much
Thanks so much for the answer.
Well, i think i did not explain well what i wanted.
I join you here the screenshot and the new GH and Rhino file: what i would like, in fine, is not the tangent, but, if i imagine how i did this in Rhino, the workflow would be:
Imagine that point 0 is the first point of the divided curve
Imagine that point 1 is the second point of the divided curve
Imagine that point 2 is the third point of the divided curve
Doing the first line line with point 0 and point 2
Construct a point at the middle of the precedent line
Construct a new line made with the precedent point (middle), and point 1
Make a little bit longer this line, in order that i can adjust the center of a box along this direction given by this line
Repeat this workflow for all the points of the divided curve, so, all the lines would be:
Line with point 0;2 (as we saw before)
Line with point 1;3 (and idem, the aim is to place the same box with the same workflow than before)
Line with point 2;4
Line with point 3;5
Line with point 4;6
Line with point 5;7
Line with point 6;8
Line with point 7;9
Line with point 8;10
Line with point 9;11
line with point 10;12
Line with point 11;13
Line with point 12;14
Line with point 13;15
Line with point 14;16
Line with point 15;17
Line with point 16;18
Line with point 17;19
Line with point 18;20
Line with point 19;21
Line with point 20;22
Line with point 21;23
Line with point 22;24
Line with point 23;25
The aim is to place the same box with the same workflow for all the 24 lines we have constructed before.
In the file i give here, i placed the 2 first boxes.
I imagine that to do this in GH, i have to create lists, but i don’t know how?
Thanks so much if you can help me!
Hi!
Thanks so much! It is what i want, but, as i put here the new screeenshot and rhino file and GH file, what i would like is to have the perpendicular line for the two dispatch lines, for exemple, i want this line on each point: point 0, 1, 2, 3, 4…
I tried to do this in the new GH file i give here, using “Shift list” for the two exploded curves, but it seems i made a mistake because it does not do that. Too, i would like to make longer the little curves, and i would like to know too, the worflow i would have to use if i want put the same box, or, the same polysurface, on each, around the direction of each little curb.
Thanks so much!
