object.
For example, I'd like to take a rectangle; move it upwards 1 unit & rotate it 30 degrees, then have another rectangle created which would be moved 1 unit upward and rotated 30 degrees relative to the second rectangle, and would then be 2 units upward and 60 degrees rotated relative to the initial rectangle. I am trying to create this process so such an array can be created x amount of times, remaining parametrically adjustable.
I can imagine the process by using a component like Hoopsnake, ultimately creating a looping effect set to terminate after n times, but I was hoping to realize a method which used only GH's native components.
See the attached pictures for a more visual explanation. The first image is an example of a single iteration of an array, while the second image is an example of what I would like to create with an input parameter such as a number slider dictating how many iterations of the cycle to complete.
Any Help would be greatly appreciated.
Thanks,
Zack
A single iteration of the cycle:
The type of result I'm looking for, while being able to control the difference with an input like a number slider.

The SmartGeometry 2011 Workshop will take place at CITA http://cita.karch.dk/This year's Challenge is entitled:BUILDING THE INVISIBLEInforming Digital Design with Real World Data
THE PREMISEVast streams of data offer a rich resource for designers. By incorporating external information into our design processes the autonomy of the design is challenged. User data, energy calculations, embedded sensing, material and structural simulation, human behaviour and perception, particle flows and force fields allows design to be situated and responsive. From the simulation of megacities to the solid modelling of material systems, design has the potential to be informed by the real. Design sits not separate from is environment but inhabits an ecological system, open, dynamic and interdependent, diverse, partially self-organising, adaptive, and fragile. Across scale and within time we now have the chance to instil architecture with an immanent intelligence creating new relationships between the user, the built and its ecosphere.THE OPPORTUNITYSystems theorists suggest that data is only a raw material. It can be differentiated from information, knowledge and wisdom. Understanding is multi-levelled: understanding of relations, understanding of patterns, understanding of principles. As digital designers our challenge is in harnessing the power of computation to assist us in informing our design process. Computers help us collect, manage and analyse the environment and inform us about an abundance of data. Our challenge is to use these inputs in a meaningful way to help us make better informed design decisions.THE AIMSG 2011 explores how the incorporation of real world data challenges existing design thinking. The SG 2011 workshop aim is to create physical prototypes of design systems to be exhibited in the SG2011 exhibition.

being driven by the wii nunchuck... But, here's my issue. I tried it first by having the output from the listener be a 6-digit number... so, I'm using the (CInt(Val(StoredValue))) command and it's writing out 181130... and I can easily split it up selecting the Left(x,3) or Right(x,3)... I first rant that number through a Format("{0:000000}",x) so that even if one of the accx or accy numbers were a 2-digit number (so my overall number would only have 5-digits)... with this Format function... I'm always assured a 6-digit number. And this method works... except...
If the first group of numbers coming in only has 2-digits... So, lets say the accelerometer read out of the first one (accx) is 89. Let's say the accy read out is 119. So, when I run this through the Format function to make it have at least 6 digits, my number now reads 011989. So, if I were to take the first three numbers on the right, my read out would be 989... which is much higher than my expected (60-180 range that is really coming over the Serial Port)... So, I'm back to where I started... in that I need to figure out a better way to split up the data.
Which brings me to your method. I tried it as well... in fact, I added a comma in the serial readout, so the string coming out of the listener reads 89,119. So, I can use your trick to go look for a delimeter and then read to the left and right a certain number of digits... The problem I still have is that the data going into the function is a string, and thus even if I split the 3 digits to the right of the comma out (so, my output says 119)... it's still a string, and my number parameter is still red. In your picture above, was your original 181 130 a number or a string? My guess is that it was understood as a number, because your number parameters at the end are accepting the value. But, in my case... I'm still stuck with the inability to convert a string to a number... Does this make sense? And are their any other workarounds?…

esult:
as you see it is not trimmed
i know that i should control the "automatic trim bolean" in "CreatePatch"
but the problem is the "CreatePath" in GH has 3 different way to work
i used the simple one: "CreatePatch(geometry, uSpans, vSpans, tolerance)"
but if i want to trim the surface i should use a more complex way: "CreatePatch(geometry, startingSurface, uSpans, vSpans, tolerance, trim, tangency, pointSpacing, felexibility, surfacePull, fixEdge, tolerance)"
i don't know what to insert instead of the "red" parameters…
will occur only after a certain amount of time has passed or a condition has been met.
When using firefly, I constantly need to wait for a data set to be filled before I send a boolean to another component.
I am trying to use python's 'time' module to mitigate this; however, it does not work like a time delay in processing or arduino would. Instead, it waits and sends all the data at once in a condition like this:
import time
a = []
for i in range(20):
if i % 2 == 0:
time.sleep(.5)
a.append(i+2)
else:
print 'better luck next time'
Another sample code that freezes:
import time
while True:
if x == 1:
time.sleep(.5)
print 'now waiting...'
a = 0
else:
a = 1
print 'finished'
break
Thank you in advance…

hit Commit.
I'm wondering how hard it would be to have an edit box which shows the
number the user could click inside of then type in a new number, then
hit enter. :)
2) How would I go about using one line from a table and assign each
field to a variable? Then, move a slider or something and use the values
from the next row?
background: I'm recreating elbows, Tees, and other fittings using
paramatric scripts, then baking and exporting them. Here's one source
table, http://www.wardfittings.com/Assets/PDFs/0902CatalogColorOld.pdf
page 5, the uniform elbows.
Current Setup: the attached ghx file. Create a point at 0,5,0 in a blank
document with units set to inches, then assign that point to the top
left 'Center Pnt' in the ghx file.
Current workflow:
a) Modify variables A, B, H, and Nominal Dia to match one line from the
table in the linked PDF file, page 5, table of regular elbows.
b) Select the 'Nodes' and 'Surfaces' with a drag box
c) Click 'Bake'
d) Switch to Rhino window, do the 'sellast' command.
e) Drag baked objects along Y axis so the center point is at 0,0,0
f) Run 'Join'
g) Run 'Cap'
h) set the 'node' points to a layer called 'nodes'
i) set the surface to a layer called 'fit-3d'.
j) select the surfaces and nodes
k) export selected
This elbow that I'm doing only has 12 rows, so doing it the above method
doesn't take THAT long. I'm also going to be doing a couple with larger
tables like the Tee on page 8, and in other spec files. As you can
imagine, entering in EACH value into a slider is a bit tedious.
I'd love to take the pdf table, run it through an OCR program to convert
to excel, modify the headers so the ghx script knows what they are, then
paste it into grasshopper, or save it and have grasshopper read it, and
I be able to move a slider or something to to select one line at a time.
Has anyone done something similar? ie: assigned one row in a table to a
predefined set of variables, each variable coming from one field in the row?
Thanks for taking the time to read this message. :)
I'm making a rhino script to do steps d-k, so that part will be much faster.

So it's not true that Bounds.X is only a getter. However it does behave as though it is. This is because RectangleF is a Value Type instead of a Reference Type. When you assign a variable of one value type to another variable of the same type, you always assign a copy of the first value. So when you request the Bounds from an attributes class, what you get is a copy of the actual bounds. Changing the X on this copy would be a useless operation which is why Visual Studio catches this mistake.
Let's assume that Dog is a class (a reference type) and it has a get/set property for fur type. Then, if I type:
Dog A = new Dog();
A.Coat = Long;
Dog B = A;
B.Coat = Short;
At the end of these lines, both A and B have a short coat, because the act of assigning A to B (line 3) means that both A and B now point to the same instance of Dog in memory. In effect, A and B are the same. If Dog were a struct (a value type), then at the end of this code A and B would have different coats, because assigning A to B means creating a copy of A. Any changes made to B will not affect A.
The one place where this causes annoying situations is exactly where you ran into it. If a property returns a value type then it's typically not useful to call properties and methods on that returned data, as it would only affect the copy of the actual data instead of the original data. That's why, if you want to change the Bounds of an attribute, you need code like this:
RectangleF box = Bounds;
box.X +=10;
Bounds = box;
On to the second problem, which is that doing it this way won't help you one bit. Laying out a component is a difficult job and the size of the Bounds depends on many things:
The display mode of the component (icon or text).
The size of the text (depending on which Font to use).
The maximum number of input and output parameters.
The maximum width of the longest input/output parameter name.
The maximum number of state icons to draw on the input/output parameters.
Changing the Bounds after the layout has occurred will basically just invalidate the parameter layout, resulting in parameter names and grips being drawn in the wrong places.
If you want to affect the size of the Bounds for a GH_Component class, you're going to have to dive in and do the laying out yourself. As mentioned before, this is not trivial.
There are static methods on GH_ComponentAttributes which are helpful when doing this, have a look at:
LayoutComponentBox()
LayoutInputParams()
LayoutOutputParams()
LayoutBounds()
Unfortunately they are undocumented.

First-End List Component cannot manage branches inside every dimensions..
"Smart T8" Component is developed for managing the multi dimensional data tree with first-end algorithm.
It works with path index location..
"-1" or negative numbers mean the location of item..
"0" means the location of the last path index..
positive numbers mean the location from the back..
----
Now look at this example.. a simple 3-dimensional boxes..
In the data tree.. of {0;0;i;j} (k)
"k" is the item index.. Y direction..
"j" is the last path.. X direction..
and "i" is the level.. Z direction..
----
When index < 0 (i.e. "-1" or negative)
"Smart T8" performs like the First-End Item Component..
It selects first items in each list and puts them out to "F"..
and in this example.. they are boxes with same Y coordinate(=0)..
In the below image..
F(Red) M(Transparent Green) E(Blue) are classified by Y coordinates..
----
When index = 0
"Smart T8" focuses on the last path index..
It selects first list of every {0; 0; i; *} set of lists.. (i.e. every levels)
In this example.. they are boxes with same X coordinate(=0)..
because the last path means X grid..
In the below image..
F(Red) M(Transparent Green) E(Blue) are classified by X coordinates..
----
When index = 1
"Smart T8" focuses on the third path index.. (i.e. 1 step from the back)
It selects first list of every {0; 0; *; j} set of lists..
Actually in this case.. they are first levels of every YZ planes..
In this example.. they are boxes with same Z coordinate(=0)..
because "Smart T8" manages levels now (index=1)..
In the below image..
F(Red) M(Transparent Green) E(Blue) are classified by levels..
----
When index > 1.. (if it is meaningless index or out of range..)
It performs First-End List Component..
It selects only the first and end list of all lists..
----
The "Smart T8" component works with 3 or more dimensional data tree well..
Please control the focusing index and enjoy it.. :)

nter the programming world and tinker more complex, interactive solutions. We will also explore advanced programming paradigms. There is no class official programming language, as both C# and Vb.Net are possible on the participant’s side, and all examples will be provided in both C# and Vb.Net. Additionally, we will see how to get started writing full .Net plug-ins. Finally, we will have time to explore user’s own proposals on the third day.
Day 1 Morning: programming introduction in .Net
• The Grasshopper scripting components. Choosing a .Net language. Language developments
• Variables declaration, assignment and utilization. Operators. Methods [functions]. Calls
• Classes: declaration and instancing. Constructors. Importing a namespace. On3dPoints, OnLines
• Arrays declaration and usage. Lists. Adding to arrays and lists, advantages and opportunities.
Afternoon: patterns
• About OOP (object oriented programming) as opposed to procedural programming. Discussion
• Example of OOP good code reuse: sorting points by coordinates using the .Net SDK classes
• Lists as input parameters. Trees as input parameters. Usage and limitations
• Finding resources: on the net with website that can help getting started and troubleshoot. And books
Day 2 Morning: extending Grasshopper functionality with our definitions
• Store data between updates. The use of fields [globals, or static locals]
• Examples on how to use stored data between updates: a simple agents simulation
• Baking geometry with scripting directly into the Rhino document. Baking with names
• Passing custom types from a scripted component to another one. Our own code reusability
• Rendering an animation from Grasshopper. How to get started and final results
Afternoon: customizing our tools
• Our Rhino plug-in with Visual Studio C# [Vb.Net] Express Edition & wizard. Parametric mesher
• Writing a custom Grasshopper component: hacking an exporter for our data to Excel
Day 3 All day: personal project
• Rehearsal on any example from the first two days. A project that you want to start on your own, being it a Rhinoceros plug-in, a Grasshopper assembly or a script. Example might be to send data through network with UDP to Processing
MINIMUM REQUIREMENTS
A good foundation of Grasshopper visual programming is mandatory. You will need a level which corresponds to the Grasshopper 101 course outline. Examples of things that will not be covered in this course are: sorting document spheres by diameter, paneling of a surface with grasshopper components. You are expected to already know these from the Grasshopper course.…
