decided to concentrate my effort today on this problem and manage to come up with a solution !
I will explain it if somebody else is looking for a similar solution.
Finally my only problem was to create an alternating true/false list that inverse at certain index, this what I came up with: I have a list of points and random index , the box and sphere represent true and false, and the blue sphere is the node(index) where I want to see an inversion.
In reality, it was pretty simple, I just didn't know the right modules. (In yellow, it's the most important part of the patch)(Sorry for the spelling mistake)
Here is a diagram of what I did: I created a list going to 1 to [number of lines], here it's 1 to 10, I had node at 3-4 and 7-8. For each node I created a list of 1 repeated [(number of lines)-index] times. Here, 7 (10-3) and 3 (10-7) times.
After grafting everything, I add everything in mass addition module. I had my final list which I checked if it was divisible by two.
It was more of a logic problem than a grasshopper problem.
Here it is the initial shape with what I wanted !

w how. Thanks for that. Now I do have some questions.
1. I am using the area weight tool. I am first calculating the volume of the form. I then multiply that value by it's density. So for concrete I am using 2400 kg/m^3 x volume. I then divided that number by the area of the membrane that is supporting the mass. This gives me my area weight. It seems to be working well but I want to verify that this is the correct workflow. I also want to verify that gravity would be turned off since I am thinking it is already calculated within the weight component.
2. I am finding that the new triangular element tool works much better than trying to use EA/L as input for the springs from mesh. Even when I set the timestep, subiteration, and drag I still have issues with getting very stiff materials to work. On the new finite elements tool I wanted to verify that E was in pascals. I also wanted to ask if I use imperial units can psi be entered. Now from what I am seeing the materials are deforming more than expected and to get less deformation and stretch in the mesh area I am finding the E value needs to be increased more than the true material values. Often I am raising E by a multiple of 10 or 100.
I am going to describe my problem and I will gladly share the definition if you'd prefer looking it over but basically I have an inflated membrane at a certain pressure made of a particular material. I then have a certain volume of concrete on top of the inflated membrane. My goal is to review the displacements as the concrete is applied over the membrane and find the proper pressures to apply to keep it free from deformation. I am including a picture from a project that we used kangaroo on and attempted to deal with such issues. It was a class sponsored by Cloud9 architecture held at Art Center College of Design where I was one of the instructors. Hopefully this illustrates the problem. To summarize any example file that shows the best way to implement real material properties and unit based forces would be a helpful reference and would be greatly appreciated.

This still leaves the problem of having more than one of a single component on the canvas. Referral can be made unambiguous by simply picking the most recent component with the same name. But how do you indicate you want a second Polyline component?
Possible solutions:
Separators in the text:[Point=SetMultiplePoints]-->[V][Polyline]----------------------------------[Point=SetMultiplePoints]-->[V][Polyline]
Keywords or symbols to indicate the creation of a new component rather than the re-use of an existing one:new [Point=SetMultiplePoints]--> new [V][Polyline]new [Point=SetMultiplePoints]--> new [V][Polyline]
(2) is a lot more flexible and (1) may not work at all as it will prevent any reuse above and below the separator.

The Barra Funda district of São Paulo was once characterised by a mix of small industrial, commercial and residential programmes, but, as economic policies have favoured larger production industries, numerous companies have abandoned the area. In response, the workshop proposes the creation of new types of smaller industries to produce a mix of both consumption and production, manifested through micro-manufacturing interventions that can co-exist alongside retail and housing. Computational design and digital fabrication could be used to help create these new micro-industries, which in turn will help empower local craftsman to produce and sell directly to consumers through micro-manufacturing, located in small urban workshops.
The workshop will tap into emergent gallery scene of Barra Funda and local initiatives that use computational technology to introduce a new cultural and economic impetus. The workshop is a part of the International Festival of Electronic Language (FILE), an exhibition of interactive electronic technology, and will import these electronic technologies out of the galler, collaborating with local manufacturers, artists, and activists, with a goal of disseminating a high-tech yet low-cost and small-scale fabrication systems to promote this new micro-industrial movement. The workshop is open to architecture and design students and professionals worldwide.…

// Agenda
Parametric Design, in the history of architecture, has defined many rules for current designers and for future practitioners to follow. One of the strongest aspects that are prominent from this style is ‘geometry’. Arguably, there is nothing new about geometry and aesthetics forming the most prominent aspect of any style or era. The language of any style, in the long history of architecture, is visually defined by geometry or shape, beyond the principles that define the core of the style. In the distinguishable style of parametric architecture, geometry has played and is continuing to play an integral role. And with this fairly young style, there are many strings of myths and false notions associated.
The workshop aims to provide a detailed insight to ‘parametric design’ and embedded logics behind it through a series of design explorations using Rhinoceros & Grasshopper platforms, along with understanding of data-driven fabrication strategies. An insight to Computational Design and its subsets of Parametric Design, Algorithmic Design, Generative Design and Evolutionary Design will be provided through presentations, technical sessions & studio work, with highlighting agenda of using data into Hands-on fabrication of a parametrically generated design. A strong focus will be made on ‘geometry’ and ‘matter’.

way of setting the camera in grasshopper to get the camera in the Top Viewport?
EDIT: Seems to be a real problem for me
Hi guys,
Love the work! Please would you consider adding a function to the horster camera components that makes them only work on a user specified viewport. That way I can have a definition set up for the Perspective Viewport and it not mess up the others when they go active.
Many thanks,
Danny
