achieving some preliminarily/conceptual Academic solution that "may" qualify as "realistic". I have several defs that do similar stuff ... but this is an Academic forum and as you can understand a real-life solution would never appear here.
But let's forget the W task (truss out of relaxed mesh with depth, known as W in our trade). See for instance a step prior the "thickness".
General guideline:
1. Create a boundary (a BrepFace) and attempt to do some "reasonable" Mesh via Mesh Machine.
2. Mastermind a policy to manage anchors (naked and/or clothed vertices). This appears easy but is impossible without code IF you want to do it interactively.
3. Separate naked edges from clothed ones (as we do in real-life in tensile membranes etc etc) in order to apply different goal parameters.
4. Relax the mesh (K231 engine).
5. Either work with a "geodesic" structure (W = 0) or make a truss out of the mesh in 4. In either case decide the real-life system in use (say a Mero KK or some other).
6. Check clash truss members issues and interactively vary vertices in order to resolve them.
7. Create all the required connectivity Trees (VV, VE, EV).
8. Mastermind the skin solution (only for experienced pros: avoid at any cost that one).
My advice? Unless you are very determined ... well ... what about choosing an easier design task?

ge curves. The source code is available as usual on GitHub, https://github.com/mcneeleurope/ShortestWalk.
Here some examples of walks on predefined and custom grids.
With equilateral grids (1, 2, 3), the shortest walk on the network is the same both counting the edge length and the number of links. With these types of grids, there are often several solutions, one of which is selected by the ShortestWalk component. If the automatic search is used (no lengths are specified), then the A* algorithm is used and this will result in a path that departs "not much" (there are more rigorous definitions) from the straight path.
With the square grid (2), the geometry is called taxicab or Manhattan, and results in the total distance being the sum between the number of vertical steps and the number of horizontal steps.
The circular grid (4, 6) shows a case in which curve distance and "link distance" (number of edges that are walked, uses Dijkstra's algorithm) results is completely different paths. This example here selects the tangential road (4) or the "city center" (6).
Finally, Voronoi diagrams (5), Delauney triangulations (7) and random mazes or labyrinths (8) can be walked, searched and solved quickly, if a solution is possible, now even if there are multiple overlapping curves.
These examples show two-dimensional grids, but it is possible to also compute (weighted) walks on three-dimensional networks.
The compiled Grasshopper assembly (.gha) and the examples can be downloaded from Food4Rhino. Join the group if you want to get updates for new releases.

al other things:1. the minimum and maximum spacing between points (a certain 'x' and 'y');2. the jump between two next points - let's say it is always 2. So if a minimum possible spacing is 'x' (pt.1) then the next one would be x+2, then x+4, x+6 etc. until it gets to x+n=y (the maximum);3. how many maximum/minimum points there are in a row - when a division reaches the minimum 'x' or maximum 'y distance I want it to stay there for a while (e.g. [...] x+(n-2), x+n=y, y, y, y, y, x+(n-2), x+(n-4)...) Therefore, what I want to get after dividing the base curve are curve pieces of following lenghts/points on the curve with following distances between them (for example):x, x, x, x+2, x+4, x+8 . . . x+n, y, y, y, y, y, x+n . . . x+4, x+2, x, x, x, x, x, x, x, x+2, x+4 . . . x+n, y, y, y, x+n . . . x-2, x, x, x, x, x-2 . . . and so on and on.As you can see the amounts of x's and y's in a row changes (Rule no.3).I've tried this with graphs and attractor points and got nowhere in almost 2 weeks (though I'm a beginner).. Perhaps someone here will have an idea :)I'm attaching a picture of what I have in mind (may be easier to understand than what I wrote for some people :))Cheers…
as one element.
Thank you

Hello Patricio, divide the beams in such a way that each boundary vertex of the shell becomes an endpoint of a beam segment.

Hi Clemens,
I did what you suggested but now assemble element doesn´t work properly. Could you please tell me how to fix it? Thanks in advance, Patricio

Comment by karamba on October 8, 2014 at 11:59am
Hi Patricio, if you flatten the 'Elem'-input at the 'Assemble'-component the definition works. The triangular shell elements have linear displacement interpolations whereas the beam deflections are exact. In order to get correct results you should refine the shell mesh.
Best, Clemens

Hello, succeeds in creating the mesh to the slab, and built the beam segment, but when I see the deformations are not expected because the beam is deformed as the slab.
Thanks for the help
PS: maybe I'm using the program for a type of structure that is not the most appropriate, as I saw in the examples of other structures. But this type of structure is that students taught
best regards
Patricio

Comment by karamba on October 9, 2014 at 10:46am
You could use the 'Mesh Edges'-component to retrieve the naked edges and turn them into beams - see attached file:91014Example1_cp.gh
Best regards,
Clemens

Dear clemens
I was doing a rough estimate of the deformation, and I can not achieve the same result with Karamba. When I make a rough estimate of the result with Karamba beams and mine are very similar, I think the problem is when I connect the shell, because there are no similar results.
I sent the GH file, and an image of the calculation
The structure is concrete The result I get is 0.58cm
thank youPatricio

Dear Patricio,
try to increase the number of shell elements. As mentioned in the manual they are linear elements. A mesh that is too coarse leads to a response which is stiffer than the real structure.
Best,
Clemens

complicated than it seems as I have an event and a subscriber method receiving data from a serial port.
In the code below, the strings received within myReceivedLines appear when connecting with the serial port (when connecttodevice is true). However they disapear when I launch another command (when homeallis true).
As you recommended in your reply, I have added the field called myReceivedLineswithin the class so that I could use the method String.Add() to all the feedback received and commands sent.
Why does the feedback dispear when a command is sent? Is the string going to myReceivedLine disappearing because they happen within a subscriber method or is it related to the DA.SetDataList() method used to assign myReceivedLinesto the output?
Many thanks!

ate):
1) go to: https://github.com/mostaphaRoudsari/ladybug/2) click on "clone or download"/Download ZIP
3) Download and extract the folder wherever you want on your machine
4) Open the folder and open "userObjects"
5) you'll see something like this
6) open Grasshopper/File/Special Folders/User Object Folder
7) Select and delete all Ladybug components
8) Drag all components of the point 5) into the canvas of Grasshopper wherever you want or inside the "User Object Folder"... it is the same thing.
And it should be fine.
Let me know if it works.
