robablemente las uniones son forzadas/rotadas levemente para que calcen.
Probablemente se puede variar el angulo de 90° entre cada pieza a un angulo que permita crear el octagono perfecto, pero habría dos posibilidades de giro entre cada pieza.
Tal vez el problema hay que repensarlo desde el octagono/poliedro que forman los triangulos en el modelo y luego generar los triangulos.
Bueno aca mi definicion y algunos comentarios:
- Hoopsnake pide una condicion inicial que solo la utiliza en la primera iteracion (input S).
- Luego hay que definir el algoritmo reiterativo/recursivo que es toda la parte de abajo. Como input se utiliza el output S de hoopsnake (en la primera iteracion es la misma informacion que ingresaste en S).
El resultado de este algoritmo/proceso vuelve a ingresar a hoopsnake en el input D para una nueva iteración.
- El output H es el historial de toda la geometria/datos procesados en las iteraciones.
Ahora te explico el algoritmo:
- Se toma el triangulo y se sacan los puntos en las esquinas.
- Se revisa si los puntos estan contenidos en otro triangulo existente y hago cull para dejar los libres (ocupo el output H del hoopsnake para ver los triangulos de las iteraciones anteriores). En la primera iteracion hago un bypass para dejar todos los puntos iniciales libres (ya que no hay historial en el hoopsnake).
- La parte de abajo es para elegir una de las dos opciones max disponibles (tu comentaste arriba que habia tres opciones... en realidad son tres opciones en la inicial, luego son solo dos opciones. No se que va a pasar si se se completa el octagono, teoricamente habría solo 1 opcion disponible, pero no pude reproducirlo por el problema geometrico).
A modo de ejemplo, en la imagen le deje todas las opciones disponibles y conecte directamente (dos para el triangulo) para tratar de generar los octagonos.
- La parte final es simple, desde el centro del triangulo se genera una linea hacia las opciones disponibles para generar un plano perpendicular para la simetria y luego se rota en 90° (que creo debería ser otro angulo). Puedes mover el slider del plano perpendicular para generar la interseccion deseada en los triangulos (0.5 para interseccion completa).
Como ya te indicaron, yo tampoco hice el tema de las areas.. pero deberia ser simple en mi definición: Calculas el area del output H (triangulos), aplicas flatten, mass addition y si el numero resultante es mayor al area de la placa que quieres, debería generar un valor falso que va en el input B de hoopsnake.
Sorry que no haya ocupado tu definicion, pero ocupe un grasshopper antiguo y ademas ya había solucionado un problema similar con un alumno el semestre pasado, asi que realicé lo que me acordaba :D
Saludos y suerte!

nputs to run (please refer to the image)
Currently, here is how I set the data:
protected override void RegisterInputParams(GH_Component.GH_InputParamManager pManager) { //Create default size
double defaultBaySize = 0; pManager.AddTextParameter("LotLib", "Llib", "Lot Library", GH_ParamAccess.tree); pManager.AddCurveParameter("BoundaryCrv", "BC", "Boundary Input", GH_ParamAccess.list); pManager.AddIntegerParameter("Direction", "D", "Direction of gridLines", GH_ParamAccess.item, 0); pManager.AddNumberParameter("CCsize", "S", "Distance from column to column", GH_ParamAccess.item, defaultBaySize); pManager.AddCurveParameter("GridCrv", "GC", "Take in curves input for gridlines", GH_ParamAccess.list);
}
protected override void SolveInstance(IGH_DataAccess DA) {/* Setup */ GH_Structure<GH_String> LotLib = new GH_Structure<GH_String>(); DA.GetDataTree(0, out LotLib); List<Curve> BoundaryCrv = new List<Curve>(); if(!DA.GetDataList(1, BoundaryCrv)) { return; } int Direction = 0; DA.GetData(2, ref Direction); double CCsize = 0; DA.GetData(3, ref CCsize);
List<Curve> GridCrvs = new List<Curve>(); DA.GetDataList(4, GridCrvs); if (!DA.GetDataList(4, GridCrvs)) { return; }}
Is there a way can set data in the way if the component does not receive inputs for BoundaryCrv but only GridCrvs, the BoundaryCrv List will empty.
Thank you very much …
t, you can see 6 (+) signs with what you can add (A,B,C,P,Q,R).
Let's say you add A = 90 and B = 50.
Now you can't add the third angle (cause its 180-(50+90) = C output).
What you can add at the moment is P,Q,R.
You choose to add P = 10.
There is no more a possibility to add Q and R.
All component outputs now give us the data.
2. Triangle with P,Q,R
When you zoom the component, you can see 6 (+) signs with what you can add (A,B,C,P,Q,R).
Let's say you add P = 15, Q = 20.
Now if you add R, the component's outputs all the angles and edge lengths.
If R > P+Q then component throws warning. (> or >= ?)
You cannot add A,B or C anymone.
3.Triangle with P,Q and C
When you zoom the component, you can see 6 (+) signs with what you can add (A,B,C,P,Q,R).
Let's say you add P = 15, Q = 20.
Now if you add C (angle), the component's outputs all the angles and edge lengths.
You cannot add A,B or R anymone.
To make it all easier, disable the possibility to internalize the data.
Tolerance issue... Maybe round the angles always to floor , with 0.1 precision ?

the use of digital technologies as architectural design tools. The workshop " Computer Aided Design: parametric design and digital fabrication " aims to do some introductory teaching in the use of some of these tools.
The workshop will focus on the use of computational models of parametric behavior for generating architectural forms. The generative capacity of these models it will be tested in the development of designs defined by repetitive non-standard components, based on the parametric control of its variations and series differentiations. This process will be developed by the use of a three-dimensional modeling software - Rhinoceros, associated with an application for visual programming - Grasshopper.
The last day of the workshop is dedicated to the use of digital manufacturing tools in architecture. Part of the work will take place at the facilities of the Institute of Design of Guimarães (IDEGUI) providing for the use of their laboratories and manufacturing CNC machines (computer numerically controlled).
At the end of the workshop, it is intended the students to understand that the use of digital technologies in architecture can overcome representational functions, and their integration in the design conception, analysis and construction enriches the methodology of project development.
Terms & Participants
The workshop will take place at the School of Architecture of the University of Minho (Campus Azurém, Guimarães) and the Institute of Design of Guimarães (Couros, Guimarães).
The workshop is pointed at students who attend the 3rd year and 4th year from MiArq, EAUM.
The maximum acceptance is 20 students and a minimum of 10 students.
Deadline for entries is April 11 and must be performed by eaum.pac@gmail.com.

nd linear/planar tectonics. Within this new field of investigation, the Stuttgart VS will be researching into novel techniques of material mixtures and grading, associative design and double curvature surface generation.
For the second cycle of this exploration we will be based at the Institute for Lightweight Structures and Conceptual Design (ILEK) at the University of Stuttgart. Drawing from the Institute’s long history of experimentation and research on tensile structures instigated by Frei Otto in the 1960s and conducted at present by Werner Sobek, this year we will be focusing on the design and fabrication of materially graded membranes, as well as the application of UHPC and FGC on fabric formworks. The workflow followed will be divided into two stages:
1. Computing Membranes: Computational form finding methods will be taught by professional engineers and architects from ILEK and str.ucture GmbH. The aim will be to utilise the latest software technologies to form find membranes for textile structures, or fabric formworks for complex concrete structures. The results will be evaluated against criteria such as internal air pressure, as well as asymmetric and wind loading. The outcome of this research will inform the material grading procedures (i.e. changing the stiffness, thickness or porosity of the membranes themselves, or the consistency of the concrete poured into the formworks) that will follow in stage two.
2. Fabricated Grading: The digitally computed membranes or formworks will eventually be fabricated physically, utilising the workshop and robotic fabrication facilities at ILEK. The objective will be to rethink conventional research on tensile and concrete structures as isotropic constructs, by customising attributes such as materiality, reinforcement, rigidity, translucency, patterning, and porosity among others. The final, graded prototypes will be made up of mixtures of materials, all accurately engineered to respond to variable environmental, structural and aesthetic criteria, in essence forming multi-material structures that have finally caught up with the latest material developments.
Prominent Features of the workshop/ skills developed:
Teaching team consisting of AA diploma tutors and ILEK and str.ucture GmbH engineers.
Access to the Institute of Lightweight Structures and Conceptual Design (ILEK), the Materials Testing Institute and Concrete Spraying Robotic facilities at the University of Stuttgart, as well as to the office of str.ucture GmbH Structural Design Engineering.
Computational skills tuition on Grasshopper, Rhino Membrane, and Karamba.
Lectures series by leading academics and practitioners in architecture and engineering.
Fabrication of functionally graded membrane and/or concrete structures.
Eligibility
The workshop is open to current architecture and design students, PhD candidates and young professionals. Software Requirements: Rhino (SR7 or later) and Grasshopper.
Fees
The AA Visiting School requires a student fee of £595 and a young professional fee of £895 per participant, which includes a £60 Visiting membership fee.
The deadline for applications is 10 July 2017.

ned' as this is kind of unknown to me, which is why I wanted to look for a tool or script that might generate some geometry between the two. The fundamental principle is that the input meshes must retain 90+% of their original geometry (ie not deformed into an approximated wrapped shape) but be joined together by some sort of mesh geometry which acts as a link between the two shapes. The form for this could be highly abstract and doesn't need to conform to any parameters other than allowing the original meshes to be highly visible. I hope that makes sense, it may only be clear in my mind now that I have pursued it this far!With regards to the geometry wrapper, I found the example file that you sent us and attempted to plug in similar variables with my meshes, however the values returned by the geometry wrapper are constantly zero, no matter what I seem to change. I am currently plugging the mesh into a bounding box, which forms the box for both the geometry wrapper and iso surface and then inputting integers for the remaining parameters, though I'm not quite sure what actions these are performing. Would it help if I could send you my definition? I'm currently trying to internalise my meshes, though my rhino keeps crashing when I try! If you aren't able to follow any of the above let me know and I'll try and put together some simple diagrams that may explain it better.
Thanks,
Tom…
