ting at multiple geometries in the same location. I simply sorted the list of values and used the Delete Consecutive component. This potentially rearranges the order of values but I don't think that matters in your case. I also threw in an Int component which actually seems to make a difference (try sidestepping it and you will see!).
2-I flattened the output of the mesh component before sending it to union. This ensures that the original mesh is booleaned once with all the components rather than individually with each of the 86 components.
Is this what the result should look like?
One suggestion for future postings: when referencing geometry in rhino, it often helps if you attach your rhino file as well so people don't have to guess where you are starting from.
If you have further questions, just ask ;-)

h, and using the BScale and BDistance are creating havoc somehow too. I've simplified first, and used the Kangaroo Frames component along with setting internal iterations, to make MeshMachine act like a normal component, along with releasing the FixC and FixV. The FixV didn't make any sense anyway. I've also set Pull to 0 to speed it up during testing, since much less calculation is involved to just let the meshes collapse, prevented from disappearing altogether by using a mere 15 iterations.
Also, your breps are open so that allows much more chaos and then collapse, though they did manage to close themselves too at times. Here is closed breps with a full 45 iterations:
So now that it's working, lets re-Fix the curves, and the problem arises that there is an extra seam line that is getting fixed too, running along the cylinder, stopping the mesh from pulling tight under tension wherever a vertex happens to be near that line:
So lets grab only the naked edge curves instead:
And what happens if we lose the end caps, now that we don't have an extra line skewing the result?:
There is no real curvature differences since it's not a curvy brep so the Adapt at full 1 setting has little to do. Now what does the BScale and BDist do? Nothing! Why? Your scale is out of whack, 99 mm high cylinders but only a falloff maximum of about 5, so let's make the falloff be 25 instead, but I must restore the end caps or the meshes collapse away for some reason and freezes Rhino for a minute or so the first time I try it:
It's a start.
If I intersect the cylinders, nothing changes, since they are being treated as separate runs. MeshMachine outputs a sequence of two outputs though, due to Frames being set to a bare minimum of 2 needed to get it to work, so I filter out the original run, which is just the unmodified initial mesh it creates.
The lesson so far is that closed meshes are much less prone to collapse and glitches leading to screw ups.
A Boolean union of the cylinders is when it gets funner, here show with and without the fixed curves that seem to define boundaries too where really there are just polysurface edges:
…
bi-directional link, the link is unidirectional (downflow only), because of the use of proxies.
Matrix transforms and persistent constraints: I don't think this is true. The parts can have mates to other parts that preserve geometric relationships like 'coincident' , 'aligned' etc. These are essentially bi-directional. GH's algorithmic approach does not do relationships in the same / flexible way. In GH, the 'relationship' has to be part of the generation method that dependent on the creation sequence. I.e. draw line 2 perpendicularly from the end of point of line 1. If you are thinking about parts or assemblies sharing, or referencing parameters as part of the regen process, this is also possible. iLogic does this, and adds scripting. So does Catia. Inventor/iLogic can also access Excel and have all the parameter processing done centrally, if required.
Consequently, scripting the placement of components is irrelevant in GH, unless you decide that each component needs to be contained in its own separate file.
I wouldn't be too hasty here. Yes, you are right about compartmentalisation. I think this needs to happen with GH, in order to deal with scalability/everyday interoperability requirements. Confining projects to one script is not sustainable. MCAD apps have been doing this for ages with 'Relational Modeling'.The Adaptive Components placement example illustrates that it is beneficial to be able to script some 'hints' that can be used on placement of the component. Say, if your component requires points as inputs, then its should be able to find the nearest points to the cursor as it moves around. I think Aish's D# / DesignScript demo'd this kind of behaviour a few years ago. Similarly, Modo Toolpipe reminds me how a lot of UI based transactions can be captured as scripts (macro recorder etc). Allowing this input to be mixed in and/or extended by GH I think will yield a lot of 'modeling efficiency' around the edges. This is a (mis)using GH as an user-programmable 'jig' for placing/manipulating 'dumb' elements in Rhino. It may even give the 'dumb elements' a bit more 'intelligence' by leaving behind embedded attributes, like links to particular construction planes etc.Even if we confine ourselves to scripting. GH is a visual or graphic programming interface. A lot of 'insert and connect' tasks can be done more easily using graphic methods. If we need to select certain vertices on a mesh as inputs for, say, a facade panel, its going to be quicker to do this 'graphically' (like the AC example), then ferreting out the relevant indices in the data tree et al. The 'facade panel' script would then have some coding to filter/prompt the user as to what inputs were acceptable, and so on.
This also brings up the point that generating components and assemblies in MCAD is not as straightforward. In iParts and iAssemblies, each configuration needs to be generated as a "child" (the individual file needs to be created for each child) before those children can be used elsewhere.
Not sure what you mean here. If the i-parts are built up using sketches /profiles or other more rudimentary features (like Revits' profile/face etc family templates) then reuse should be fairly straight forward. I suppose you could make it like GH scripting, if you cut and paste or include script snippets that generate the desired Inventor features.
One of the reasons why the distributed file approach makes perfect sense in MCAD, is that in industry you deal with a finite set of objects. Generative tools are usually not a requirement. Most mechanical engineers, product engineers and machinists would never have any use for that.
I don't think this is true. Look at the automotive body design apps, which are mostly Catia based. All of the body parts are pretty much 'generative' and generated from splines, in a procedural way, using very similar approaches to GH. Or sheet metal design. It's not always about configuration of off-the-shelf items like bolts. And, the constraints manager is available to arbitrate which bit of script fires first, and your mundane workaday associative dimensions etc can update without getting run over by the DAG(s) :-)

es has guided me in a - what I once thought - specific path within architecture, but recent discoveries (like the Grasshopper-community etc.) have learned me that the field of digital and parametric architecture is so-to-speak alive and kicking. This is also the main subject I would like to write my thesis about. It is however mainly the subject and defining its boundaries – what do I really want to explore and research? – which is the most difficult factor at this time.
A concrete idea is non-existant, and my current visions will probably be redirected when I have a first meeting with the promotors in February. Moreover there is the knowledge that it is impossible to make a thesis at the institute in Antwerp on no matter what subject in the world of digital architecture. Understandably too, it’s a small world and does not always result in realised projects, but in impressive imagery. At this moment however, I am thinking of two possible research fields to focus on.
In a first option the focus might lie on how digital design tools can be used to bring a certain aspect of interactivity to building facades. Such interactivity can occur both in the design phase and throughout the use of the building. The first scenario, in which the interactivity occurs when designing, I would focus on how the designer can shape a building’s outer perspective in function of environmental parameters: obstacles, elements that block sunlight from entering the building, visually important landmarks, etc. It should be noted however that focus will mostly lie on the design element, and less on the energy-efficiency and sustainability. Tools that will be researched would include Grasshopper, Rhino Scripting, Processing and ParaCloud.
A second possible approach could be categorized under both Swarm Intelligence and Generative Design and might study how the aforementioned digital techniques might be implemented in the new urbanism. We notably see more (innovative) interventions in which the design and planning is heavily influenced by movement patterns and morphogenetic parameters and functions. Based on the outcome of these scripted techniques, designers tend to work towards a proposal which answers a certain urbanistic issue.
All additional insights, guidelines, tips, comments are more than welcome in order to help me define the scope of my thesis subject. I must admit I am pretty new to this digital design world (it is not actively promoted at my home university, but it is promoted at the university where I am studying for one year now) and thus have limited experience at the time of writing.

what they really mean by that, as in what buttons to push, so I assume it's a Windows Path entry?
2.) Modify PATH
Add the install location on the path, this is usually: C:\Program File\IronPython 2.7
But on 64-bit Windows systems it is: C:\Program File (x86)\IronPython 2.7
As a check, open a Windows command prompt and go to a directory (which is not the above) and type:
> ipy -V PythonContext 2.7.0.40 on .NET 4.0.30319.225
Tutorial on setting a Windows environmental variable (path):
http://www.computerhope.com/issues/ch000549.htm
But this fails to point out that path contains many entries already separated by semicolons so if I merely add a new variable called "path" it's likely that I will destroy existing program function. There's no info on how to just tack on another entry, and the Windows 7 edit box doesn't even show the whole collection, but one item (!), so I copied the existing path into a text editor to see the whole collection successfully and added the C:\Program Files (x86)\IronPython 2.7 entry after an added semicolon, correcting for an Enthought page typo of no 's' on the end of "Program Files". I also checked the others and many pointed to old missing directories so I deleted those entries.
...and the test fails and "ipy" is not recognized as a command, even though the path now shows up using "path" in the Windows CMD window, that is if I copy all by right clicking and pasting the stuff into a text editor to really view it all. I can run it from the source directory just fine.
The rabbit hole was indeed deep. Using the Task Manager (control-alt-delete) to kill Explorer and then Run in the menu to restart "Explorer," along with restarting the Windows CMD window however, worked. I can now invoke Iron Python ("ipy") via command line from any directory. For the "path" I edited path in the System Variables and not the User Variables. No, you don't have to type that whole crazy line above just to test the path variable, just "ipy" (and control-Z to quite IronPython) in the CMD window invoked by typing "cmd" into the Start menu search box.
From the CMD line this step did work fine:
3.) ironpkg
Bootstrap ironpkg, which is a package install manager for binary (egg based) Python packages. Download ironpkg-1.0.0.py and type:
> ipy ironpkg-1.0.0.py --install
Now the ironpkg command should be available:
> ironpkg -h(some useful help text is displayed here)
But of course Step 4 fails, giving pages of what seem to be error messages;
C:\Users\Nik>ironpkg scipy
Traceback (most recent call last):
File "C:\Program Files (x86)\IronPython 2.7\lib\site-packages\enstaller\utils.
py", line 92, in write_data_from_url

File "C:\Program Files (x86)\IronPython 2.7\Lib\urllib2.py", line 509, in http
_response
...
Why can't I just download Numpy as a normal file and thus also have it easy for other users to install it when they use my scripts? This is just crazy and lazy. The Enthought developer has turned this into a computer game, with a missing registration link and then the last step spits out errors with utterly no information on how to fix it manually.
This Step 4 error is covered here:

ating to new speakers.

Adding new speakers for your automobile could improve the sound quality dramatically. Some sound technicians say it is the number-one update you may make to improve the overall quality of your vehicle.
"They do not care how it sounds. Speakers are often form of continue on the list. Updating to new speakers offers you a much fuller sound."
There is a whole lot to pick from in regards to car speakers. (Photo from Eldon Lindsay)
"New speakers will make a greater fidelity and clarity of sound," states Robert Nevitt, proprietor of Audio Electronics at Indianapolis. "The audio is more different without distortion. People will not get bored listening to it."
Cook says customers need to pick the type of sound they enjoy. The very first thing Cook does having a customer is sit in the car together to talk about their personal taste.
"Everybody's ear is different," he states. "That which I believe sounds great, you might believe is dreadful. It is a fantastic idea to get outside and listen to everything you enjoy and do not like about doing it."
When you've discovered a sound you want, you are going to discover the sky's actually the limitation in regards to purchasing car speakers. There are scores of manufactures and models, sizes and power levels to select from.
Columbus Car Audio & Accessories offers three types of automobile speakers to pick from: complete array speakers, component speakers along with coaxial speakers.
• Total range speakers arrive with a tweeter to make to your high-pitched sounds along with a woofer for those lows. This option offers a number of different sizes.
• Unit speakers, nonetheless, include separate tweeters and woofers.
• Coaxial speakers arrive with a tweeter plus motorist.
When you've selected a type of automobile speaker, you are going to want to determine how many you desire. Cook states some cars arrive with as little as just two speakers, whereas bigger, luxury vehicles might have too many 32. He adds a normal sedan generally has four. What are The Speaker Sizes in My Car | Speaker Size for My Car
"It simply depends if you would like to replace all of these," Cook says. "I would advise doing all of four. If you are budget-minded, I'd begin with the ones at the front. That is where you are at. And you are likely to be at the automobile 100 percent of their moment."
Subwoofers are designed to reproduce low bass frequencies also may be included with new speakers or could be added separately to existing car speakers.
"Many speakers can not play down low in these frequencies such as a subwoofer may," Cook says.

Wondering about speakers? Below are a few techniques to establish a home entertainment experience whatever your budget.
A speaker update might charge as little as $100 up to a few million dollars depending on the scope of job and type of speaker.
Cook states that the price of a subwoofer can operate as low as $37. Columbus Car Audio & Accessories sells a subewoofer bundle that includes an amplifier and a enclosure for about $ 299.
To get a set of automobile speakers, Columbus Car Audio & Accessories begin prices at $39, with an average price tag of about $70 for setup. Adding an anti-vibrator into a set of speakers prices an additional $25.
Nevitt, meanwhile, fees as little as $99 to get a set of "some good speakers." The price of one hour of installion, that is typically how long it takes to put in a set of speakers, is 67.
However, most customers spend far more.
"Paying a total amount of 800 to $1000 isn't from this world of possibility," Nevitt states. "A price somewhere in the center could be $400 or $500."
Cook says several vehicle speaker technicians began with DIY projects and adds there is nothing wrong with trying to set up car speakers all on your own. But you are going to want the correct tools for your job along with just a little understand. Installing speakers requires carrying out your car door.

Choosing a professional to set up speakers ensures that the job is done correctly.
"If you do it yourself, then you might wind up breaking something. That is some thing we do everyday. I am not planning to inform you we will not violate something. But we will look after it if we perform. We all do so with being honest and up front with people."
If you are getting speakers set up, experts say to expect to place an appointment to the setup. …
