igher degree than 1 might have the same shape as a line, but it won't have the same parameter distribution.
In fact, look at a sine curve:
The red crosses are spaced along equal x intervals. These represent the parameters. As you can see the actual distance between any two subsequent crosses is not constant, even though their parameter distance (distance along x-axis) is.
Nurbs curves suffer from the exact same problem, it's just that they are proper 3D curves which are defined by 3 separate equations for all three world axis directions.
If I ask you what the coordinate is for this curve at x = 2.3, it's very easy to compute:
{2.3, sin(2.3), 0}
If I ask you what the coordinate is for this curve at 2.3 units along its length, you'd probably be stuck.

h other etc etc). Then randomly do the yellow lines (in X or in XY or in XYZ). Do not bother if the segments have equal lengths. Get the pairs of points (at end/start). Compute the big box (white).
2. With "help" boxes off this is the situation:
3. Do a Voronoi using the pair of points as above and the big box:
See that "equal" length lines means nothing with regard the "random" appearance of the cells.
If the deployment of the boxes (as in 1) is "flat" (meaning: no stacks in Z) then we have just a juicy Voronoi rectangular pepperoni pizza.

ts (that should make whole structure rigid body, right?).
Questions
1
In KarambaManual there is component called "BeamJoint" but i dont have it is it available only in pro version?
2
Is there other method form makeing my structure rigid body?
3
Should all lines be flatter before going to "LineToBeam" component. Unfortunately my system crash when i try to do that
Best,

tions and that will be the end of it. I will not look for you, I will not pursue you. But if you don't, I will look for you, I will find you, and I will continue to ask the aforementioned set of questions. Good luck.

Question 1: How do I go about measuring the arc length of a parabola in Rhino? In a nutshell, I'm looking to accurately measure curve length in Rhino in this case using a parabola.
Question 2: Once I can measure the arc length of a parabola, how do I go about manually changing it to a specified length (Ex: If my arc length is 14, but I need it to be 24)? Followup question, is there a way to use a slider in Grasshopper to do this?
Question 3: Once I eventually am able to create a parabola of a specific arc length/curve length the next thing I'll be doing is to create a parabolic cylinder comprised of 6 inch squares (view image below for visual cue). Is there a way to change the scale of a parabolic cylinder while still maintaining the 6x6" grid/panels? I plan on using a 3D printer to print out 6x6" interlocking tiles that when glued will form a parabola, and would like to be able to do it for a variety of parabola sizes.

nts which are located on different surfaces of these boxes. Now I want to divide the points in such a way that I have all the points located on each different surface in a branch of a list.
So if I have a tree for the points with 10 branches (for 10 different situations) and 4 different surfaces the points can be located on. I would like to have one tree as a result where I have the following struture:
{Situation 1, Surface 1}
{Situation 1, Surface 2}
{Situation 1, Surface 3}
{Situation 1, Surface 4}
{Situation 2, Surface 1}
...
{Situation 10, Surface 4}
My goal is to make individual surfaces based on the point clusters on each surface.
For now I tried the Point in Curves function, but somehow I still get points on different surfaces even though I should just get them for one of the surfaces.
Kind regards,
Florian…

Computational couture looks at the creation of exclusive custom-fitted clothing (typical of haute couture) through the lens of a systemic approach, extending the sartorial techniques with 3D modeling and computation-based approaches developed in Rhinoceros and the visual programming environment Grasshopper.
Aim of the workshop is to exert, infuse and expand the sartorial sensibilities to body proportions and dress making into an algorithmic approach that loops through design and fabrication by means of laser cutting and 3d printing for the design and production of a garment. Participants will be divided in teams focusing on specific aspects of the garment related to the production technique (laser cutting or 3D printing).

Il workshop introdurrà le nozioni base di Grasshopper approfondendo le metodologie della progettazione parametrica e le tecniche di modellazione algoritmica per la generazione di forme complesse. La didattica è organizzata secondo moduli che coprono gli aspetti più importanti del software e prevede lezioni frontali ed esercitazioni guidate.
Il corso è rivolto a studenti e professionisti con esperienza minima nella modellazione 3D e si articolerà in lezioni teoriche ed esercitazioni. Sarà rilasciato un attestato finale.
La nostra attività formativa nasce dalla volontà di promuovere le nuove tecnologie digitali di supporto alla progettazione e condividere il know-how maturato attraverso ricerca, realizzazioni, pubblicazioni, collaborazioni con le più importanti realta professionali ed accademiche a livello internazionale.

s will learn to use these extensions in order to integrate numerous tools for analysis and simulation in the architectural process.
This course aims to develop a link between the virtual and the real context model through structural or environmental simulations, using other software or plug-ins dedicated. Through this link the virtual model receives physical properties that can further modify and adapt the initial model. This creates feedback loops that can optimize the design to provide an object responsive to environmental conditions.
Curriculum
Mesh subdivision with Weaverbird, continuous surfaces without NURBS
Genetic optimization with Galapagos, optimal search
Physical environment feedback with Diva and Geco, solar and day lighting analysis
Adding physical properties with Kangaroo Physics, interactive form-finding
Linking the parametric model with structural analysis using Karamba, structural performance simulation
Extracting data with Firefly and Kinect, 3D scanning and human movement tracking
