"And this ... well ... does what you want and is 10 times simpler ... but doesn't teach you anything about the black art of intersecting Lists (critical in line graphs). PS: add some stuff with regard disjointed mesh pieces."

peter fotiadis replied to John's discussion Sorting points
"Yikes + Yikes: A vertex index in mesh.Vertices is not the same in mesh.TopologyVertices. The former is required in order to get the naked status and the latter ... in order to make the VE/EV connectivity correctly. See attached."

i am an architecture student and my tutor is focusing on this precedent study way too much i think he basically wants me to do it as my project haha whatever i do he is like go back that tower that ive showed you. I am new with grasshoper started learning it this year and he told me to look at brunching, bone structures and exoskeleton. Thanks for the reply xx

Dear Peter, 

I am trying to replicate a tower that looks like this in grasshoper by using l systems and branching  would you be able to please help and tell me what you would be the best to do

Hi peter, i have been searching for weeks on end for a solution to my project modelling , and i think you have it. I am making a spatial project involving tree like structures and branching forms, and i stumbled across your discussions here:

http://www.grasshopper3d.com/forum/topics/surface-deformation-with-points?id=2985220%3ATopic%3A1204695&page=1#comments

and also had a look at your files. i found the fuse fractal test you did with Tsplines was really what i needed, i intend to use it  in a similar as it is used here: http://www.l-a-v-a.net/projects/uae-geometrical-forest/

I would really appreciate it if you could coach me through how you generated the lines on GH. I hope to hear from you soon Thanks in advance

Ire
