HI , i am trying to flow a polyline ( crv 1 ) along a generic curve (crv 2 ) [image] i need to make sure that the polyline segments are preserving their original lenghts and that start and end points of the 2 curves will be coincident thus through scaling crv2. I tried ( method 1 ) with Kangaro…

nice approach. I like that you first scale the polyline and convert the absolute distances to relative ratios. (which is a bit hidden by the orient-component) - so kangaroo actually solves a bit another problem: how to divide an entire curve by straight segments in given ratios. … and finally s…

[image] Tom_P: just wondering, if you set the tolerance of the solver to 1.0e-12 and turn on profiler, how much time does the solver need ? my solution is way off :slight_smile: what you have seen in my above post is wrong due to the fact that start/end points were not forced to stay at the …

[image] another manual, modelling solution - no scripting, no grasshopper. divide the target-curve with the given distances (red circles). scale the target curve and move it up (i used 100 mm) now loft the curves to get the surface. This (all-scale-factor-)surface represents different scaling-…

[image] inno: I think a custom Kangaroo Goal is needed for this case, where all the lines lengths get scaled alltogether [image] Daniel Piker: LengthRatio is the Goal you need for this in Kangaroo I need to study SO MUCH MOOOORE… :+1: as speed/result comparison ( @Tom_P ) Flow_scale_D…

[image] Tom_P: is this what you re after ? thats it , correct!!! :slight_smile: [image] Tom_P: (I used a script to find it - with recursion and a tolerance of 1.0e-12 in 27 ms) woww its very efficient !!! as i said i am not skilled with scripting but im trying to learn more , the lea…

@Tom_P @inno I want to thank sooo much for placing so much effort on this challenge , i am delighted by the quality of your approaches and proposals to solve the problem, I am not as skilled as you are but you discussion is super interesting and it’ll keep me busy tonight to study it and learn s…

Hello a bit late to the party, here a way of doing with curve divide distance and Galapagos. [image] Curve Divide Distance from Nautilus plugin but you can use Divide Distance Multiple [image] How to divide the curve by the varying distance? Grasshopper Late to the pa…

HI Laurent the logic in your definition is clear and Nautilis CDD component is very useful. i tried to run the script but i don’t know if i am doing something wrong but it does not converge. Galapagos stops generating solutions almost immediately without reaching convergence and when the list len…

Hello I used Maggic Eddy yesterday, and I swapped with my tool. I surely forgot to test it with Galapagos. I just see that my tool if the factor is too low it puts a point at the end of the curve so it stops Galapagos. I advise you to use Magic Eddy tool for now or use this script that add some t…
