X, Y & Z parameters. At the moment 'Z' parameter is set to 0.
Now when i use a planar surface components it works well. But because i have Z parameter i need Edge surface component to work well. Edge surface gives me a funny shape, not like planar surface.
Essentially with Z parameter as 0, edge surface should look like planar surface, or not?
When i try edge surface with simple 4 points it works. The moment it gets relatively complex i do not get desired result.
All the points 1-26 in the curve were formed progressively in order i.e. 1, 2, 2...26 in GH not in Rhino.
What m'i doing wrong?
cheers

i have come as far as creating a mesh entirely in GH to my desired form. Could any-1 please help me with creating fenestrations / holes into this mesh in GH?...
I have been stuck with this since a week now...not able to find any solution to move ahead!
i have Tried Voronoi by converting this mesh in to surface...it doesn't really work on the mesh that i have created...
any-1 with some suggestions?
cheers

The comand prompt window (see attached image) seems to put -ad 1000 as default even if it seems to be set to 512 in grasshopper. In contrast to -ad, the modification of -ab to 3 has been taken into account. Have you set minimum values for RADparameters? If yes, would it be possible to force them to custom values?
Thanks in advance for your help

troducción a su plugin de modelado paramétrico, Grasshopper.
Con este tipo de herramientas podemos pensar formas más allá de las cajas para diseñar, porque seremos capaces controlar con total rigor geometrías muy complejas.
En el siguiente video, podemos ver un ejemplo realizado durante un curso impartido anteriormente en Madrid por el profesor, Francisco Tabanera, en el que se realiza una interpretación del proyecto de BIG para la Biblioteca Nacional de Kazajstán.

next level.
This Parametric Design course will provide the participants with the necessary knowledge and ability to use Grasshopper, a free visual programming plugin in Rhinoceros; you will be guided through a series of hands-on exercises that highlight NURBS modeling and its concepts. We will introduce Grasshopper as a graphical algorithm editor tightly integrated with Rhino’s 3D modeling tools. You will also learn how Rhino is used to render models for visualization, translate 3D models for prototyping, and export 3D models into 2D CAD or graphics programs.
English is the course main language.

ll geometry.
The difference with programs like Inventor is that they are made for production, regardless of the fabrication method. I won't go into detail about that, and instead focus on the modeling process.
In this little model, the starting point actually is a bit obvious, the foundation.
The only contents in the 3dm file are 27 lines. These indicate the location of each footing, and the direction of the tilt of each column. Everything else is defined in GH with the use of numbers as input parameters.
Needless to say, instead of those lines you could obviously generate lines and control the number of columns and panels, hence establish their layout, with any algorithmic or non-algorithmic criteria you please. That marks a major difference between GH and Inventor.
You can generate geometry with Inventor via scripting/customization (beyond iLogic), with transient graphics for visual feedback similar to GH's red-default previews. However Inventor's modeling functions are not set to input and output data trees. I won't go into detail on that, but suffice to say that the data tree associativity of GH was for me the first major difference I noticed. I've used other apps with node diagram interfaces like digital fusion for non-linear video editing since the late 90's, so the canvas did not call my attention when I first started using GH.
Anyways, here's a screen capture of the foundational lines:
In the first group of components, the centerlines of the rear columns are modeled:
And the locations in elevation for connection points are set. Those elevations were just numbers I copied from Excel, but you can obviously control that any way you please. I was just trying to model this quickly.
The same was done for the rear columns:
The above, believe it or not, took me the first 5 hours to get.
Here's a screen capture of what the model and definition looked like after 4 hours, not much:
If you're interested, next post I can get into the sketching part you mentioned, which is a bit cumbersome with GH, but not really.
I wouldn't say that using GH to do this little model was cumbersome, it just needed some thinking at the beginning. You do similar initial thinking when working with a feature-based modeler.…

the optimizing process I am using Karamba+Galapagos.
Unfortunately I am getting some errors when calculating the maximum displacement of the bridge, using the Karamba “analyze” component.
95% of the times (when moving a slider), it goes well. I am getting deformations of 100-200mm as expected, and the deformed shape in the Rhino view looks good.But in the last 5%, I get unreliable deformations of 50000mm or more. What I dont understand about this is that the deformed shape in the Rhino view still looks normal. Another weird thing is if I move the slider away from the position and then back to the same position again, I suddenly get the result of 100-200mm. It seems more or less randomly when it gives the strange results.
The model has over time become pretty big. When moving a slider, calculation time is about 5 to 10 sec.Could this be the reason for the errors? Any other ideas about what goes wrong?
Thank you in advance for your answer.Attached please find the GH file.

oxes in the most efficient way within boundaries of object and follow the following constraints. The Goal: To fit 125 boxes in the most efficient way inside the total area. Starting Variables: (1) 40% of the Boxes need to be between 60 and 85MSQ. (2) 40% of the boxes need to be between 86 and 110MSQ.
(3) 20% of the boxes need to be between 111 and 125mSQ. The breakdown doesn’t have to be exact to give the script some flexibility. Meaning you can have 41% +39% +20% = 100%.
Constraints:
1. A total MAXIMUM area of approximately 1600M per layer.
2. A maximum of 8 layers for a total of 12,800M per layer. Optimization can make as little or as many as 8 layers vertical to accommodate all boxes. So if script can achieve with 3 levels great. If needed all 8 levels, that's fine too. However, pay attention to next constraint (#3).
3. Approximately 15% of that space on each layer is off limits. (internal area) (blue area in example script) and the shape of the boundary cannot be modified to accommodate box design resulting in jagged lines for the internal area.
4. All generated squares/rectangles must have at least 3m touching an outside border (The Green lines).
5. All boxes must also be touching minimum 1M of border of the blue line.
6. If the boxes generated go outside the green boundary, they must be fillet to maintain the straight lines of the green boundaries.
7. Get as many of the boxes as possible a view towards the dots.
Could any one provide me a method or a way to start, if there are any useful links, please share with me. Thank you!…
