start (if there is a better one I would appreciate a hint), but I thought I populate a rectangle with points, interconnect the points to later let the borders of the rectangle attract each other.
I have 4 rectangles: A, B, C and D.
On each I have 20 points (A0-A19, B0-19, etc.)
Now I want to connect each point to all the points on the other rectangles, e.g. point A0 with all the (60) points on rectangle B, C, D.
I saw the discussions about the topic sorting lists (e.g. flipping), but I didn't see them fitting on this problem, or I don't know how to abstract them for me.
Also this is a problem I am having with another definition, so if someone could help me with that list stuff, I think I could use it furthermore.
But if there is a better solution to the rectangle organisation (tessellation), I am open for that.
regards,
Max
sry for the long text…
per space. In the upper right corner you draw another dot, and you write "1, 1" next to it. You now have 2 points defined in paper space (uv space).
Ok, lay down the pencil and pick up the paper. You'll notice that the two points have just moved through world-space. They were very close to the desk, but now they are hovering above it. The coordinates you wrote down on the paper or the other hand are still valid.
No matter what you do to this piece of paper; crumple it, fold it, take it on a plane to South Africa, those two points remain fixed in paper space.
A surface is always a rectangle in Rhino. It may be deformed, it may have holes cut into it, but in the end it's always a rectangle, just like your piece of paper. UV coordinates are points that are defined in Surface UV space. They consist of only two numbers, because a surface has no thickness. At any point in time, you can translate these UV points into World XYZ points using what is called a surface evaluator. Where these XYZ points end up depends entirely on the *shape*, *size* and *location* of the surface.

Surface uv-space (and Curve t-space) are vital when dealing with nurbs geometry. If you do not understand the concept of parameter space, you will have a lot of problems because many components in Grasshopper use these coordinates.

orm of the model but when I try to add the piping to it, I get the message saying Windows has ran out of memory.
I am using Windows 7 and have tried going into the BCD as recommended here: http://wiki.mcneel.com/rhino/memoryincrease but I was not able to run this command.
I have then tried to increase my virtual memory within Windows, even up to 30GB with no luck.
I'm pretty sure I'm doing something really wrong here but I really need to get this modelled ASAP for a portfolio submission.
Any help would be very much appreciated!

d the workshop PDF from this link: http://goo.gl/bcvRNH Download event poster from this link: http://goo.gl/Q0KWCM Brief: Cairo is filled with barriers controlling people movements, suppressing them as well as detaining green and public spaces to the extent that most people have been taking these spaces for granted. Public spaces have been for a while the periphery of our daily life. We will explore in this workshop how we can manipulate and alter people’s perception and direct their attention to how these spaces are integral for city life. This exploration will be backed up by intensive technical tutorials introducing computational design and fabrication techniques and tools mainly Rhino, Grasshopper, Geco and Ecotect. Not only will this be the typical technical workshop, but rather you will also have the chance to be guided step by step on how these tools are used through out different design stages in a real world scenario. Design prototypes will be produced through 3D printing, the main workshop output will be a fabricated one to one functional model for one of the designs using our new in-house CNC machine. Tutors (check the PDF for bio): Olga Kovrikova, MArch DIA Alexandr Kalachev, MArch DIA Karim Soliman, MArch DIA Islam Ibrahim, MArch DIA Sherif Tarabishy, B.Sc. AAST Application: Application deadline 1 September 2013 ** For students (undergrad / Master), teachers and PhD proof of status is required (university ID with a date or a certificate of enrollment) to apply for the students package.

ou will see all of the available components on a ribbon at once so there is no need to keep clicking drop down menus.
It's all about discoverability with GH. What if you're a beginner and don't know about the Create Facility (dbl click canvas) how can you find Extr?
Even if you hover over every component or use the drop down lists you will not see the name Extr appear anywhere.
Sure it makes sense that Extr is short for Extrude but it's also the Nick Name of Extrude to Point component
So you can easily miss the fact that one has a Distance Input verses a Point Input.
I think I made the move to Icons around about the move from version 0.5 to 0.6, possibly before. I initially thought that I would go back to text because I loved the mono chromatic look of the text but I soon realised that Icons were the way forward. The greatest benefit is speed. You don't need to digest and decipher every component (which is written 90 degrees to the norm).
I'm not saying you should move to Icons forthwith but at least consider that once you have a better knowledge and understanding of GH, Icons will set you free.
My top ten tips that I would highly recommend to anyone wanting to better themselves with GH.
1) Turn on Draw Icons
2) Turn on Draw Fancy Wires
3) Turn on Obscure Components
4) Use the Create Facility like a Command Line eg "Slider=-1<0.75<2" or "Shiftlist=-1"
5) Use Component Aliases to customise your use of the Create Facility eg giving the Point XYZ component an alias of XYZ will bring it up as the first option on the Create Facility as opposed to the other possibilities.
6) Try to answer other people's questions even if it's not relevant to your own area. By looking into solving a problem outside of your comfort zone and then posting your results it is very rewarding but it also lets you see the other approaches that get posted in a new light.
7) Take the time to understand Data/Path structures.
8) Buy a second monitor - There is nothing that can compare to real estate when working in Grasshopper.
9) Read Rajaa Issa's Essential Mathematics
10) Pick a panel in a tab on the ribbon and get to know every component inside and out and then move on. Start with the Sets Tab > List Panel…
) function if you've already got a boolean value.
This expression:
x < 12
results in exactly the same things as this expression:
If( x < 12, True, False )
If() is only really useful when you want to return non-boolean data, like so:
If( x < 12, x, 100-x )
In this case, the expression will return either x, or 100-x if x is larger than or equal to 12:
x result
1 1
2 2
10 10
11 11
12 88
13 87
14 86
18 82
70 30
