an that HashCodes well ... since they are "unique" per item (even if this - for the one reason or the other - is created at the same location with that) I barely can see how one can use them in order to get rid if "equal" items (Lines in this occasion).
On the other hand ... well ... using HashSets sampling the Line center and testing length and direction ... well ... this works but why bother? > if you are not doing business with code (thus you need this "check" internally) > use the Kangaroo1 component.
That said the topic of "equality" is rather huge and most people are confusing a lot of things on that matter: for instance a point not equal to another ... well ... that's rather simple but a brep "not equal" with some else ... this is not that easy (if it's solvable).…
th one element which is a list of 10 numbers?
I can flatten it and get (I think) a list of 10 elements (even though when I hover over the output of "Flatten" it says "Tree(T) as tree"). I'm surprised I can flatten at all what would appear to common sense to be a simple list of 10 numbers.
I'm hoping that if I can get this answered it will become obvious why we have trees of lists rather than just lists of lists as you would in most computer languages. That's my real goal - to understand the purpose of adding what seems like an unnecessary complication - trees - to the concept of lists in GH. It seems to me as though a "tree" is just a list of other "trees" until you get to the leaves where you can have "lists" which are identical to trees but can have something other than a tree in them. Whether you can have lists of trees or trees with no lists I'm unclear on. Do the leaves of trees have to be lists? Do lists have to be contained in trees? It would appear from the series example where a tree is produced for no obvious reason to contain the list that this is the case but given that you can flatten it, I guess not - or is the "List" I see in the param viewer just another type of "tree"?
I've found many tutorials that talk about how to manipulate trees and lists and I've managed to get along fairly well with them so far, but nothing seems to explain the reasoning behind the existence of trees and the philosophy for how and when they should be used and when lists should/could be used and precisely what the difference is between them.
Sorry to be long winded but I'm so confused!

P.S. I've seen David Rutten's diagram with the colored leaves in Grasshopper Primer 2 and that seems helpful. It would appear that trees can only have lists at their leaves and lists can't have trees although I'm not sure that it comes out and says that directly but at least there are no examples of this shown in his tree diagram. I thought I had it down pretty much so decided to test myself. Apparently I'm as confused as ever:
It certainly appears to me that this tree has two levels - a first level with one limb and a second with 10 limbs - and that I should be able to index it with {0;0} and retrieve a tree with one item in it - the list {0}. The panel data seems to confirm this with indices of {0;0;0}, etc. so I put this path in with quite a bit of confidence that it would work and...bust. The error reads "Path {0;0} does not exist within this tree". Huh? Again, I'm just so confused.…

elivering their latest workstation and graphics technology.
Intensive computing and exceptional graphics technology will deliver generative modeling and computing to its next level.
Participants will learn the ease of use of Grasshopper within Rhinoceros, so they could start creating their own generative design.
Who should attend:
1. Professionals in design and engineering industry who would like to gain more knowledge and productivity
2. Students who would like to extend their knowledge to the next level
3. Supporting IT who would like to provide even more efficient tools for engineers and designers
4. Engineering and Design Enthusiasts
Participants should send an email to fani@m3kom.co.id, to receive an invitation and its detail.
For further technical information about the event, feel free to ask Rendy (tihe.tihe@gmail.com).
This event will consist of the sneak preview of most anticipated real-time rendering for Rhinoceros: V-Ray RT for Rhino.
Hopefully, this will also initiate the establishment of Indonesia's generative modeling designers community in Indonesia.…
this workshop is to materialize a chair designed with help of generative algorithms via robotic fabrication. To design the form of the chair we will go through an intensive course of generative design techniques, k-means clustering, structural analysis and optimization done with the help of Anemone, Galapagos, Millipede and other plugins. Finally we will employ a 6-axis robot with custom tooling to fabricate the chair via robotic rod bending. No prior experience with Grasshopper or robotic fabrication is required, although basic knowledge in 3d modelling would be an asset. // APPLICATION The deadline for application is 13.03.2017 Apply by sending email titled ‘workshop_chair’ to workshops@aan1.net // INFO If you have any more questions check the www.aan1.net website or contact us with email workshops@aan1.net // FEE We have special pricing for students, as well as an early bird offer. Check the Eventbrite list to get more details. Please bear in mind that a limited amount of seats is available (minimum 8 people, maximum 16).

p 10 "Scripting Reality – Integrating 3D Point Clouds in parametric design workflows".
This research-based workshop will introduce participants to thegeometrical class of point clouds and ways to handle, manipulate, analyse and script with them. Participants will as well have the chance to get first-hand knowledge in the handling of 3d capturing devices and to link their outputs directly into a design environment.
The workshop poses especially the question of how changes on architectural scale can be tracked over time. Related algorithmic concepts and the Volvox plugin, allow for the first time to directly access and manipulate point clouds in a parametric design environment, will be introduced to the workshop participants. A 1:1 experiment on the ETH campus will provide a testbed. Participants will learn point cloud processing and learn to track objects solely on the base of point cloud analysis, find deviations against the planned and visualise the results.
The workshop is led by Mateusz Zwierzycki, Martin Tamke and Henrik Leander Evers. FARO provides several 3d scanners with helical adapters and acccess to the FARO SDK for the workshop. The workshop is modestly priced with 160CHF.

It seems a problem with python.. Thanks in advance for any help.…
p; 3D Urban ModelingOn the topography subject I get the next message: "One or more boundaries may be outside the bounds of the topo dataset" I'm not sure if it's the .IMG file I'm loading since I found so many IMG files nearing my polyline area (Miami Lat:26 Lon:-81 aprox.) or maybe my polygon doesn't match the topo area? I have no idea why it isn't working :(On the Shapefile subject, haven't been able to find a Building Height SHP File, so far have downloaded around 8 SHP files which only contain Polylines, my solution is to meanwhile randomize Z heights, but of course this data is not "technically" correct.P.S.: I've already tried all example links and also the ones posted by you and Benjamin in this video.Been strugling last few days, hope you can help me, thanks in advance!!…
