mber of assumptions can be safely made, and this is not the case for equations with unknown behaviour. The initial division may be too coarse to find a specific peak, and this approach cannot handle discontinuities either.
Assume we're trying to find where a function becomes zero, within some domain. We know ahead of time that there may be any number of solutions; zero (x²+1), one (x+1), two (x²-1), many (Sin(x)) and even infinite (Sin(1/x)).
So we evaluate the equation at 9 values, dividing it into 8 spans (the dashed purple curve is how the search algorithm sees the equation). We immediately determine that none of the spans crosses the y=0 line, so either we give up or we focus on spans 5 & 6 as they got closest. We'll never find the two solution in span 3.
Or maybe the equation results in a discontinuous graph, like so:
It seems as though the answer must be somewhere in span 4, but no matter how hard we search there, we'll never find it.…

s para acercarse al diseño paramétrico.
El curso esta dirigido a arquitectos diseñadores e ingenieros de diseño que pretendan implementar las técnicas del modelado por parámetros dentro de sus herramientas de proyectación.
La duración de dicho curso es de 20 horas, repartidas en 6 sesiones los días lunes y miércoles de 5pm a 8:20pm, en el espacio cultural calle nueve (calle 9 # 43b-75 abajo del parque del Poblado. https://www.facebook.com/calle.nueve). El curso dará inicio el día lunes 22 de Agosto de 2011. El máximo de inscritos por curso es de 15 personas para garantizar la calidad de la enseñanza.
Este curso estará dictado por los arquitectos Ana Maria Bustamante Y David Vanegas arquitectos de la oficina de arquitectura interior137 (www.interior137.blogspot.com) que cuentan con más de dos años de experiencia en el manejo de GRASSHOPPER, y tienen una trayectoria reconocida como docentes en la Facultad de Arquitectura de la U.P.B.
Para participar en el taller los estudiantes deberán tener un computador portátil para su uso personal, durante todo el curso, además deben tener instalado el software Rhino versión 4.0 con la actualización SR9, y un conocimiento mínimo del modelado y la interfaz de este software.
Contenidos:
Sesión 1: * Introducción al modelado por parámetros y al diseño mediante algoritmos.
* Grasshopper: datos + acciones. Interface.
Sesión 2: * Datos fijos, datos variables: Parámetros.
* Puntos, Curvas parametrizables.

as follows.
We have a grid which consists of a collection of columns, where each column consists of a list of points. You said flattening is out of the question, so we need to cull items from each list individually.
Let's say our culling pattern is KDDDKDD (repeat as needed). K = Keep, D = Ditch. If a column contains 18 points, the pattern needs to be repeated until it is 18 items long. In this case:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
K D D D K D D K D D D K D D K D D D
We can now cull each column, but they will all be culled in the same way. By shifting the pattern one more index for each column, we can cycle the culling.
The fix incidentally is to Shift the pattern PRIOR to repeating it. Then it works as expected:

the same C:\MapWinGIS_installation_folder\gdal-data folder, which is: C:\Program Files\MapWinGIS\gdal-data in your case, I assume.
It seems as now your system is allowing the deletion of the osmconf.ini file, but not the creation of a new osmconf.ini file.
Can we now try the following please:
1) Shut down both Grasshopper and Rhino2) Restart your system.3) Make sure you are logged in as Administrator once the Windows boots up.4) When it boots up, again in your Start menu's search box type: "UAC". Click on it and check if the bar on the left is still set to "Never notify".5) Download the osmconf.ini file attached below.6) Check if downloaded osmconf.ini file has been blocked: right click on it, and choose "Properties". If there is an "Unblock" button click on it, and then click on "OK". If there is no "Unblock" button, just click on "OK".7) Copy the osmconf.ini file to your C:\MapWinGIS_installation_folder\gdal-data folder8) Right-click on "Rhino 5" icon and then choose: "Run as administrator".9) Download and open the newest create_3dbuildings_trees_streets.gh file from here.

ocessed once Grasshopper is done with whatever it's doing now.
3) Grasshopper tells the Slider object that the mouse moved and the slider works out the new value as implied by the new cursor position.
4) The slider then expires itself and its dependencies ([VB Step 1] in this case, but there can be any number of dependent objects).
5) When [VB Step 1] is expired by the slider, it will in turn expire its dependencies (VB Step 2), and so on, recursively until all indirect dependencies of the slider have been expired.
6) When the expiration shockwave has subsided, runtime control is returned to the slider object, which tells the parent document that stuff has changed and that a new solution is much sought after.
7) The Document class then iterates over all its objects (they are stored in View order, not from left to right), solving each one in turn. (Assuming the object needs solving, but since in your example ALL objects will be expired by a slider change, I shall assume that here).
8) It's hard to tell which object will get triggered first. You'd have to superimpose them in order to see which one is visually the bottom-most object, but let's assume for purposes of completeness that it's the [VB Step 1] object which is solved first.
9) [VB Step 1] is triggered by the document, which causes it to collect all the input data.
10) The input parameter [x] is asked to collect all its data, which in turn will trigger the Slider to solve itself (it got expired in step 4 remember?). This is not a tricky operation, it merely copies the slider value into the slider data structure and shouts "DONE!".
11) [x] then collects the number, stores it into its own data structure and returns priority to the [VB Step 1] object.
12) [VB Step 1] now has sufficient data to get started, so it will trigger the script inside of it. When the script completes, the component is all ready and it will tell the parent document it can move on to the next object (the iteration loop from step 7).
13) Let us assume that the slider object is next on the list, but since it has already been solved (it was solved because [VB Step 1] needed the value) it can be skipped right away, which leaves us with the last object in the document which is still unsolved.
14) [VB Step 2] will be triggered by the document in very much the same way as [VB Step 1] was triggered in step 9. It will also start by collecting all input data.
15) Since all the input data for [VB Step 2] is either defined locally or provided by an object which has already been solved, this process is now swift and simple.
16) Upon collecting all data and running the user script, the component will surrender priority and the document becomes active again.
17) The document triggers a redraw of the Grasshopper Canvas and the Rhino viewports and then surrenders priority again and so on and so forth all the way up the hierarchy until Grasshopper becomes idle again.
[end boring]
Pretty involved for a small 3-component setup, but there you have it.
To answer somewhat more directly your questions:
- The order in which objects are solved is the same as the order in which they are drawn. This is only the case at present, this behaviour may change in the future.
- Adding a delay will not solve anything, since the execution of all components is serial, not parallel. Adding a delay simply means putting everything on hold for N milliseconds.
- [VB Step 1] MUST be solved prior to [VB Step 2] because otherwise there'd be no data to travel from [GO] to [Activate]. The only tricky part here is that sometimes [VB Step 1] will be solved as part of the process of [VB Step 2], while at other times it may be solved purely on its own merits. This should not make a difference to you as it does not affect the order in which your scripts are called.

ntains only 1 item. So there is no 3 and 9 in this branch. It stems from the circle and the points having different path structures at the input to the move component circled in red.
With regard to the pipe split:
You have chosen to cap the pipe with rounded ends thus making a Closed BRep (Polysurface) so the best way to trim it is to extrude the splitting surface up into a closed Brep and do a Solid Trim.
Alternatively if it was just a single surface (no caps) you could use the Surface Split component to trim it like the image below.
Note that you need to check your data structures further upstream as you are getting duplications or null values.

I followed these instructions, succeeded to build Tetgen, placed the built files in C drive directory and tried to run the definition. Then some WindowsError came out as follows which I don't know how to fix.
My working environment is;
OS is Windows 7 Ultimate 64 bit.
Rhino is version 5, 64 bit.
Grashoppper is version 0.9.0076, the latest version at this moment.
It would be great if I can have some help advice / comment.
I appreciate for your attention.
