st work on lists? There may be a good reason for this, I just cuoldn't work it out while skimming the code.
2) I'd recommend declaring variables at the last possible moment, not all at the top of the file. It makes it very difficult to see what variable is used where that way. Also, if you change code, it's a lot of work figuring out what variables just became obsolete.
3) In VB.NET you can declare for loop iteration variables inside the loop, cleaning up the code: For t As Integer = 0 To X
4) If statements with conditionals should not be written like this: If (value = False) Then. There's nothing technically wrong with it, but the general rule is to write If (Not value) Then or If (value) Then.
5. Things like k = k+1 can be written shorter in VB.NET, namely k += 1. I just think that looks cooler :)
6. In VB.NET, Exit Sub is still legal (for legacy purposes) but the Return keyword is to be preferred.
7. I'm happy to see you're using sensible variable names and casing.
8. For a program like Grasshopper, one would expect to get the same results when the same setup is run at a later time. That means creating Random instances with a fixed seed value, not DateTime.Now.Millisecond. If your result depends in any way on the seed value, it should be kept constant.
On the whole pretty good work, code is quite self-documenting, properly commented and fast. Hats off.

s the "Surface Populating" definition: I manage to populate my geometry over the surface, but after I bake it, I have to delete the boxes that define my components limits as well! Is there any way of populating and baking only the chosen component, without having to delete the boxes afterwards?
Secondly:
Basically: I am trying to cover a surface with two types of components [ an open one and a closed one] , which will be proliferated over my tubular surface according to the main sunlight direction.
1. I introduce the surface component.
2. I use "Divide Interval2" in order to have division into U and V.
3. i generate the target boxes [ "surfaceBox"] .
4. I use "Isotrim" ( same intervals) and "BRepArea" to find centroid of each area.
5. My "Curve" component introduces sun angle, with its "End Points".
6. I use "Vector 2Pt" to specify sun-light direction.
7. I want to measure the angle between sun-light and the surface normals, at the position of each component; after generating the centre points, I need the normals of each centre point to get the surface's points' UV, and "Evaluate" the srf at points.
8."Angle" and "Vector" components: I use them in order to evaluate the angle between the sun direction and the srf.
9. I convert this angle to degree by using a "Function" [ to see if the angle is bigger from the max.angle or not...]
10. Function "x,y" gives me boolean data.
11. Data become "Dispatch"ed...
12. Two "Morph" components , each one linked to one part of the "Dispatch" data, generate "closed" and "open" components over the srf.
The result should have been different types of components, based on the surface's curvature, diraction and sun-light direction...
I do not understand where the mistake is in this definition...
Thx in advance1

Component its manage a CSV like a Database, i found that the csv native Python module doesn't work in IronPython cuz its compiled in PythonC (or something like this), so i found a .Net module that can be imported to IronPython to work with CSV file
So Here a
Pseudo Code of my Toughs
1 - Import .net Module.
2 - Read Csv File. by a Path Assigned by interactive Imput.
3 - Identify the Header of The Csv File.
4 - Create a List of the Fields found in the Csv Header for Further (Sorting, Retrieve specific, create relations with others files by fields in commons, etc. etc. (whatever can imagine))
5 - Read the Data of the Csv File
6 - Out put the Attributes of the Header. (simple list of the fields to identify with what we deal for )
7 - Out Put a list of all the Attributes of the Header ( Complete List of the Fields by Rows Found in the Csv File.
8 - Out Put a list of all the Data inside the Csv File in relation with the Point 7.
over here's my thoughts Any Comment or Suggetions for the Component ?
i will be posting a Github for this, to all who want to collaborate with this.
i'm doing this cuz i'm dealing with a lot of amount of data in my Thesis Project, wich its focus on managing Shapes files, and Csv Files of Data that are not in the same dataset, so i need to relationate a lot of things just to develop my examinations techniques about the city.

nded from the centerline at a specified thickness, which may vary along the stent.Two parameters, tmid and tend, control thickness variation
along the segment’s longitudinal direction according to the kinematically admissible Hermitian
curve:
t (d) = tend + t(3d2 − 2d3) 0 ≤ d ≤ 1
t = tmid − tend
where d is the normalized distance along the segment’s
NURBS curve between its endpoint and midpoint. This
form ensures there are no discontinuities in thickness at
the segment midpoint or at the interface of segments in the
overall stent.
2)These normals are then checked and subject to a filleting
procedure to remove re-entrant corners, resulting in
two external sets of boundary coordinates defining the
external edges of the segment’s mid-plane.
3) This plane of nodes is then extruded at a specified angle
(see Section 2.3) to generate a 3-D set of nodes defining
the finite element mesh.
4) These nodes are then mapped to cylindrical coordinates.
5) Finally, 20-node brick elements are generated for finite
element analysis.
I have generated the centerline using 8 control points with degree 7 .
Would be great if anyone can help me with the drawing the normals from the centerline of specified length governed by Hermitian equation,so as to generate the 2D model of a stent (Please refer to the attached figure of a 2D stent and extruded figure) ,using Grasshopper.
The centerline of a single stent segment is representedas a NURBS curve.…

Is this only related to my PC then?? What should I do to solve this issue?

ation production and consumption that represent our physical world in numbers and complex networks. The advent of computational systems has not only helped in developing data production but also in transmitting data between different disciplines including architecture through fields of numbers/codes. Historically, numbers and proportions played a vital role in architectural production, now; the complex flow of data is opening unexpected territories for architects. Data Flow is an advanced computational design workshop that focuses on capturing, processing and utilizing real time data from the surrounding environment by means of physical computing and parametric design tools, enabling the participants to develop informed design solutions that adapt to the environment. The workshop knowledge objective is to reconsider abstract data as a design opportunity by developing the quantitative flow of data as a qualitative design approach. /// Application To apply, please follow this link to fill the application form https://docs.google.com/forms/d/1xzKn-cZzfvu24ktTNP1ElGBAufdryfLNCXvpheucrS8/viewform /// Fees* 1700 EGP for students / 2000 EGP for graduates and young professionals * 20 % discount for early registration and payment before 22 nd of August 2014 more info on the workshop webpage: http://www.encodestudio.net/#!dataflow/cslb…
am having from Energy Plus.
I made a simple building with around 20 zones. I spent a lot of time in drawing this so it should be ok when it comes to tolerance issues. In any case it is MUCH better than other models I've simulated.
However I get around 3700 lines on my output and a total of 73 warnings and 38 severe errors.
The warnings have to do with the message "one of the surfaces has less than 3 identical coordinates and has been removed". The errors are various, ranging from FenestrationSurface erros due to invalid building surfaces, adiabatic surfaces cannot have windows or doors (even though I believe I did not set any surfaces as adiabatic), adjacent surface not found, etc. I attach my file and by running the simulation you can see the range of errors.
I am still running EP 8.1 btw, should I update to the new version?
I will start looking into my open zones. It is true I have some walls with holes (more like ventilation shafts) but I thought it would be ok. Also, I don't know for the life of me why I get surfaces with such a small area or why surfaces are removed. I tried to play with tolerance, and the above errors are with minimum value of 0.1. Many more come with 0.001.
Any insight would be appreciated. Also, do you think it would be possible to have some kind of component that can pinpoint the surfaces that give the error. Atm I can only see hexa names and not sure how I can select them.
Thank you very much in advance!
Kind regards,Theodore.…
se and compute the SP s in the 3D graph?
3. In the meantime, I made a very heavy model in which I can calculate a limited amount of shortest paths. See the attached image.
This is a beehive design. The combs which are inhabitable on both sides are radially distributed around a central core. There is a corridor around the inner core, as well as a peripheral gallery. Bees can also move above and below the combs. So I need the 3D dimensions in my model, or my mathematical imagination is not capable of thinking this planarly? I used the library from this link https://github.com/danilnagy/gd_tools but my model is very heavy. I made a triangulated mesh in order to define all the paths that the bees can take and defined random 20 points as start and end points to find the SPs. I guess with your system this would be faster. This image represents how I would like to think of the nest spaces and connectivity but in the honeybee nest case- which is a designed one not a natural one-…
