the use of digital technologies as architectural design tools. The workshop " Computer Aided Design: parametric design and digital fabrication " aims to do some introductory teaching in the use of some of these tools.
The workshop will focus on the use of computational models of parametric behavior for generating architectural forms. The generative capacity of these models it will be tested in the development of designs defined by repetitive non-standard components, based on the parametric control of its variations and series differentiations. This process will be developed by the use of a three-dimensional modeling software - Rhinoceros, associated with an application for visual programming - Grasshopper.
The last day of the workshop is dedicated to the use of digital manufacturing tools in architecture. Part of the work will take place at the facilities of the Institute of Design of Guimarães (IDEGUI) providing for the use of their laboratories and manufacturing CNC machines (computer numerically controlled).
At the end of the workshop, it is intended the students to understand that the use of digital technologies in architecture can overcome representational functions, and their integration in the design conception, analysis and construction enriches the methodology of project development.

Basically, I want to create a workflow to automatically subdivide a building mass envelope geometry into different floors which will be further subdivided as perimeter zones and core zones.
But I encountered an error for a particular building mass geometry (a quite regular form) which doesn't work with the split building mass component (see item 4&5 below):
The workflow is:
1. import building mass geometry:
2. divide the building mass into floors (one zone per floor) using one of the two different methods depending on whether the floor surface has holes or not:
3. use the split building mass component to further divide the zone for each floor into perimeter zones and core zone:
4. I tested several building forms which work for this workflow as shown below, except for one form C05 which is a courtyard block with small tower blocks on top of it:
5. in the last step, there is an error from the split building mass component saying that "solution exception: index out of range: 0" ...
So, I wonder if this is error is related to the split building mass component or related to the way the building mass geometry is created.
Appreciate your kind advice!
Thank you!…

balls の代わりにplanarカーブを直接入れてみましたがエラーが出ます。
ファンクションにしてみたところ、forループので作った数値が反映されていません。
ファンクションのインスタンス?を出力していないと思い上記のようにしましたがエラーが出てしまいます。
以上の事から自分の認識が正しいのかよくわからなくなりました・・・
python自体の深いところをわかっているわけではないので余計こんがらがりました。
そこで、for b in ballsはどのような条件または使い方であれば使えるのでしょうか?
そして、上記のように別のオブジェクトに対しての使い方はどのようにすればできるのでしょうか?
2:同じファンクション内のdist = rs.Distance(self.pos,b.pos)についてですが
この文章も for b in balls によってbはBallのインスタンスであると定義?されたためb.posがbの位置であると分かるのでしょうか?
pythonは定義しなくても動いてしまうのでどのような時に使えるのか文章見ただけではよくわかりません・・・
大変細かいことかもしれませんが、よりpythonをしっかりと理解するためにも、どなたかわかる方ご教授いただけると幸いです。…

is useful to replace values (even if I cannot replace the same value for example "fraction radiant" in two different internal gains), but not to add new stuff, as in our case.
As you may recall, we were able to add our internal gains through the additional strings, but we have the problem of the default ones that we can not change or remove.
We've noticed that People, Lights and ElectricEquipment Internal gains are located inside the "runEnergySimulation" honeybee command inside the Python script.
We were thinking of two possible quick alternatives while waiting to be able to fully customize the internal gains with honeybee.
For the first one, if it is possible, you could make a "modified" "runEnergySimulation" command for us in which you cut off the Internal Gain parts, so that we can add them as text in the additional strings part. Alternatively you could show us where to add the additional strings we need inside the runEnergySimulation command so that we can add the values we need to run the simulation.
For clarity, these are the internal gains in idf file we need (that are inside de gh file in the panel just below the additional strings command)

both my plotter/cutter and wide format printer. I had been running the plotter from my main work laptop - a Win10 machine via the plotters USB port. As it turns out you can't get Win XP drivers for this USB connection so I needed another solution.
I tried to use the plotters DB25 serial port connection using an old DB9 to DB25 modem cable I had in my collection = no luck the plotter wouldn't talk. A bit more research and it turns out these plotters need a 'null modem' cross over cable to operate. I found a pic of the correct wiring online and made up my own with some cable and connectors from the local electronics hobby shop.
With this hooked up and using Hyperterminal I was able to fire some codes to the plotter directly and get a response back - winning!
At this point I got my original code working with the 'net use' redirect from LPT1 to COM1.
HOWEVER - being that the plotter was now on a COM port there are a few more interesting things you can do with it - one is being able to read the paper size/cut area from the printer.
So what I needed to to was find a way to send and receive data to/from the plotter using the serial port.
A bit of research into .NET's serial port interface and using a bunch of small pieces of test code I have manged to completely re-jig this driver.
Upgrades include:
- Direct Serial Port comms using Null Modem cable (a USB to serial adaptor + null modem should also work)
- Plot area read from the plotter - a rectangle the size of the plot area is placed on a separate layer and coloured red
- Testing to see if selected plotting curves are both closed and inside of the cutting area - with errors shown and exiting if they are not right.
- After plot 'parking' of the plot head at the end of the cut items + an adjustable offset (currently requires manual resetting of origin on the plotter before for next cut)
Great thing is it is now 100% running within Rhino Python - no DOS command line calls = no flashing up of the CMD wind. Also no temp files needed on the HDD and no limit to number of curves that can be plotted - tested with 200 or so with no issues.
Overall very happy with whole project - have learnt a LOT about Python and .NET interfacing AND ended up with a very handy/useful tool.
Cheers

ll the wires gone. Now you'll have to hook them up again. This is the sort of thing that gets annoying after the third time.
Problem #2. The solution in Grasshopper iterates over all objects and solves each one in turn. Of course a lot of objects depend on other objects, so it usually becomes a cascade of objects solving themselves for the benefit of other objects. It is therefore very difficult to predict the order in which objects are solved.
The root iteration is the same as the display order (back to front), but the topology of the network complicates matters greatly. If you change the topology of the network during a solution, you might end up with whole portions of the network not being solved at all, or, worse, a conflict in the topology checker that makes Grasshopper think a network is self-referencing.
Problem #3. Grasshopper caches all manner of things about a network that can be recomputed from basic principles, but take a long** time to do so. If you start to expire caches where I don't expect you to, we'll either run into null reference errors, or stale cache data, or invalid cache data. Problems like these are very difficult to track down.
Problem #4. File IO. Components get deserialized from ghx files based on their default layout. In your case, we need to solve a component before we know how many outputs it needs. This cannot be done until the file has been completely deserialized. It's a chicken and egg problem, which will result in missing wires every time you open a file.
If you want to have a flexible number of outputs on your component, I'd suggest you add a menu item to your component that will change the output list when clicked, then causes a recompute. This way you won't mess with the network topology during solutions and people don't get their connections pulled out from under them. You'll need to do quite a few things to make this work, but I'll be happy to help you out there:
- Adding menu items and menu click handlers
- Properly removing parameters from a component
- Properly adding parameters to a component
- Recording undo for parameter changes
- Writing custom settings to a ghx archive
- Reading custom settings from a ghx archive and making sure your component is compatible with the ghx layout before it tries to deserialize itself.

r visual programming tools in the games world. MS's Kodu, looks interesting. Kismet and Visual3d look even more interesting..... mainly because they are more 'interactive' or 'reactive', rather than DAG-based.
Seems like the evolution path for GH-similar apps is:
1. base 3d or CAD app based on C/C++ code.
2. Add scripting language interface
3. Add some kind of visual interface
4. Add graph sorting / propagation engine
5. Re-jig base 3d or CADD app to make managed/interpreted scripts run faster, multi-threaded.
6. Add dynamic typed language, DLR stuff
6. ....
6. Add constraints solver...?
7. Rebuild CAD display engine to be procedural at the GPU level?
Seems like there are available tools for converting scripts into some kind of flowchart. There are even visual debuggers. MS even has something called the 'Debugger Canvas'. Spreadsheet constraints.
Seems like the time is ripe for lots of new apps like GH.

strictly with code (BTW: did you crossed Rubicon?).
1. See this: Imagine a curve (say a "rail") that is divided N times and then circles are created with random radii. Circle control points (9, that is) are sampled (obviously) into a DataTree where branches are the rail divisions. Let's call the control points: "start" seed points.
2. Imagine a capability ... that stores all these (the original "seed" control points) into a "parameter" and then each time that a change occurs to them (varying the x/y, on a per point on a per branch on a per plane basis[that provides the Z]) stores the "modified point" into the parameter (at the same index with the old: meaning "deleting" the old) ... and then some other code gets that data and makes curves and lofts them. Reset means: sample again the original "seed" points into that "parameter". Closing are reopening the definition has no effect: the lofted stuff is derived from the (internalized, so to speak) modified points (from the "parameter").
3. A variety of "automation" is available: for instance if you jump from branch to branch and from item to item the value of the selected point is inquired and the sliders that control the new x/y are "set" to 0,0 (meaning no change - yet) values. There's mo "store" mode: it works automatically as far as you modify points or you hit the reset button
4. This does that (only achievable with code):
5. Obviously points can been replaced with anything ... and thus ... we can individually modify items in collections ... and forget for ever attractor points and all that (OK where appropriate, he he).
I'll post 30 similar examples soon in the forthcoming mother of all threads: "GH goes (at last) interactive". Watch this space.
BTW: study the "animation" where points with index 6 are "sequentially" modified. I've added some delay in order to give you time to get the gist of the whole thingy.

4 explode the text
5 select the exploded text, which are now curves, and the border from step 2 and use the planarsrf command again
6 make your surface using the two curves at top and bottom and a section. Use the sweep2 command
7 select your negative text surfaces and use the flowalongsrf command
maybe the scale of the text can be edited by the size of the surface or of the text but I bet you can figure that out! good luck!…
