There's other dedicated apps for handling huge amount of data (using very fast ball pivot algorithms for dealing with the gazillion of points).…
Get plenty of RAM. Windows 32-bit can assign 2MB of Ram per process, so if you have lots of RAM, you can run Rhino+Grasshopper in memory all the way. I'd say get at least 4GB, and preferably 8GB. If you have a 64-bit machine, then it pays off to go even higher than that.
2) Get fast RAM. Memory access is the main bottleneck in many applications, so the faster the RAM the faster most apps will work.
3) Get a fast processor, rather than lots of slow processors. Only a few apps out there can truly use Multi-Threading (Rhino and Grasshopper cannot). These days, CPU manufacturers try and dress up multi-core CPUs as the next best thing. It is not. It is a lie. Until software can truly run on multiple cores there is no benefit to this. If rendering is a big part of your job, then it does pay off to have a multi-core machine though.
4) Get a good graphics card. I've always preferred NVidia over ATI, but there are many good ATI cards as well. You can go for a gaming card (they're cheaper), but note that these are optimised for drawing triangles. If you get a professional card, it will draw lines and curves much faster.

on) ... the only way to do something meaningful/realistic is to follow Bentley System's way: they had 3 rendering engines (all highly problematic and archaic), a bunch of highly paid "gurus" to "develop" the dead fish and an export to Maxwell capability as well (Maxwell is very slow and has no chance VS Nexus, see below). PS: "Gurus" had no idea about Quest3D and the likes.
At the time, I was near to some permanent ban (he he) from all Bentley Forums due to my acid writings about how stupid these methods were. In fact I openly proposed to Bentley (to Ray Bentley to be exact) to fire all "gurus" involved ... and follow the outsource path.
Finally Ray (he's very smart) did the right thing: after an agreement with Luxology ... now Microstation (the core product) uses the Nexus engine (as found in Modo). This means that the Nexus is fully integrated across the whole vertical suite of BIM AEC Bentley apps the likes of AECOSim (that includes Generative Components as well).
And as everyone knows THIS is the real McCoy (US movie industry is behind that thing).
Additionally Modo has the best GUI known to mankind (US movie ... blah blah) and astonishingly innovative thinking (US movie ... blah blah).

ents instead of code ... it could yield a nightmare of components (and a myriad of parameters). For real-life designs I would never attempt to do this without code.
2. A certain experience with Kangaroo (or some min surf other thing since using K on these ... well may be the killing a mosquito with a bazooka thing). That said I'm a great admirer of Daniel's work. But on the other hand why not?
3. A "certain" experience with trusses/space frames.
4. A "certain" experience with instance definitions (that's not doable with GH components).
5. Years of experience with parametric feature driven MCAD apps - Image35 (NX/CATIA) for designing the real-life parts (that have NOTHING to do with "abstract" concepts).
In total I would say that a similar "app" with code (excluding the min surf/mesh thing) would require 6-10 full days of work (or even more).

ject that involves the design of an app that allows people to interact with a 3d model through some sliders.)
Ok, imagine you have a symmetrical shape like the one i drew:
What I intend to do is to have different 3 sliders that allow me to adjust the 3 distances (x, y, z) independently of one another.
-1st question: my idea is to draw the curves in rhino, then use the "divide" and "list item" components to extract the points I need. Is it correct? :D
-2nd question: the "move away from" component can be used in a symmetric way?
(I try to be more specific: with only one slider, can I move both points 5 and 6 simultaneously about the axis i drew?)
-3rd question: is there a way that allows the curves to reshape themselves as I move the slider related to the distance between a couple of points?
I hope I have been clear ;) I would greatly appreciate any help you can give me!

ess more memory on 64 bits. So you can load larger files and generate more data.
Every time you store something in memory it has to be stored at a specific location. We call this location an address. The first thing you store can be stored at address 0*. If that thing requires a total of 18 bytes, then addresses 0 through 17 are used up. The next thing you store can then be stored at address 18. And so on and so forth. At some point you run out of addresses and when that happens there is no more room to store any new data and there is thus nothing more that your app can do and that's usually when Windows shoots the application in the head and buries the remains behind the chemical sheds.
The total number of unique addresses that can be represented by a 32-bit integer is 4,294,967,295 (4 GigaByte). However Windows only allows a 32-bit app to access 2GB, or potentially 3GB if a special switch is set. A 64-bit application is allowed to use 64-bit integers to identify memory addresses, which means the highest possible address is now 18,446,744,073,709,551,616 (or 18.45 ExaBytes). Basically, as long as you have RAM to back you up, a 64-bit application will not run out of memory. Of course it may still become prohibitively slow as a lot of data requires a lot of computation and 64-bitness does absolutely nothing to make things go faster.

* Not true in reality, Windows will already use up some of the available memory just to load the application.…

quite know where I'm going wrong. I can say that I have successfully put together a separate file which will send data directly to the Arduino (switch on a boolean toggle and watch an LED light up... how fun:) but receiving the data is a bit more complicated. For a long time, I was getting a continuous loop error, which would freeze my app. I've changed around the code (see attached file), but I'm still not receiving any data from my COM port (which I know is definitely working because I can turn on the Serial Monitor from the Arduino IDE and see the data coming in). I did have one question: Can you call different routines inside the script class (from Grasshopper), or do you have to always call the run script subroutine? If you guys have any suggestions I would greatly appreciate it. I understand it's a bit tricky to trouble shoot this issue since you may or may not have an Arduino handy to stream the data to your computer... but let me know if you see any glaring issues with the code.

nd me to kill him but give him my regards anyway) is still around in BirdAir Italy ... talk with him.
3. Hope that you understand that designing the "details" means some decent MCAD app + FEA + this + that. "Fusing" this with some abstract graphic editor like GH ... is ... er ... impossible (in real-life, you know, he he ). Generative Components on the other hand may qualify but requires a lot of time in order to fully master it (approx 2-4 years).

My realistic (low cost) advise:
use K1/2 (especially if you are after "parametric" exploitation(s)) ... and then diversify tasks: stuff for the structural department, stuff for whom claims that he can(?) design the "details" ... whilst be in a constant contact with the membrane provider (and in fact: the contractor for doing the real thing as well)

this, you'll have no horizontal force at the roller, but you will have it at the pinned support. If you wouldn't, then the structure will be displaced.
Usually, in 2 dimensional structures, if you want to know if an articulated structure is isostatic (as opposed to hyperstatic, which is what you have right now) is to use the following formula:
b+c-2·n=0;
b being the number of bars, c the number of constraints you have and n the number of nodes. In your case: b=19, c=3 (displacements constrained in X, Z at your pinned support and only constrained in Z at your roller support) and n=11, so: 19+3-2·11=0.
