a machine that is light and very sturdy. I have taken my Macbook Pro all around the world, carry it with me every day, even dropped it a few times and its still totally fine. Its thin and light.
2) You get some actual support for your hardware even a few years down the line. My Macbook Pro is from 2012 and I can still walk in to any Apple Store and get help with it, which I have done many, many times in different places around the world - I never had to show a receipt or was charged any money for help. There is no PC/Laptop manufacturer in the world with anything close to that, because companies like Asus, Dell, etc. bring out dozens of new versions of laptops every year, so its much harder to service them after a few years.
3) This is the most important one, which usually people forget when they say that Macbooks are overpriced: Resale Value. If you have ever tried to sell an old PC/Laptop (I have a few times), you will know how little value they have even after just 2-3 years. Macbooks retain their value very well and even after 4 years you can still get 50% of your original price.
4) Of course you can install Windows on it and it runs perfectly. I have MacOS and Windows on it and both run absolutely fine. On the Windows side I have Rhino+GH, Maya and a few others. Having Windows is good, because some software still only runs on Windows (looking at you, 3DSMax!). Most other software also runs on MacOS. In the interest of sanity it is great to have an alternative to Windows for all the day to day stuff, like Mail, Calender, Photos, Presentations, etc. that just always works.
5) As for performance: Yes, Macbook Pros dont necessarily have the latest and greatest in graphics cards (the rest is on par with PC laptops), but unless you want to play games you will not need it. VRay RT can do GPU rendering, but you wont get great performance from a Notebook GPU anyways and it doesnt make sense to do rendering on a laptop (especially since you have a workstation). You could get one of the older Macbook Pro Retina Late 2013 or Mid 2014 models with the GTX750M by Nvidia, which will be usable to render using VRay RT, but of course not huge performance. Better to invest in a good used graphics card for your workstation like an Nvdia GTX980ti, which is the best value for money for GPU rendering right now (lots of used ones available).
So at least consider also getting a Macbook Pro. You can buy refurbished models (depending where you are) and they are like new, but a lot cheaper or even get an older one thats used. It will be a worthwile investment.
Take it from someone who has used dozens of PCs and Macs in my lifetime and have to do the IT support here at work (where we also use both).
I still have my Macbook Pro Retina from 2012 and its still running perfectly, super fast, and I can use Rhino and GH for huge files, do GPU Rendering with Octane Render and all sorts of other heavy computing stuff.
Hope that helps.…

hat differ in shapes, sizes and height the facade would be a mess. Some spaces need some light while other can't have any. I would like to have full freedom of creation inside the building, to make it as functional as possible. Thats why i decided the parametric "skin" solution would be best. Since the location has industrial past (factories made of brick) i decided that brick would give interesting result.
I tried creating the definition on my own but since i lack skill in GH i got some problems (especially multiplication of bricks and the diffrence between each "level" (half a brick on y axis) caused problems for me.
I post my simple sketch explaining the idea of definition i would like to create (sorry about quality):
1 - Brep - I would like to use 25x12x6cm (classic brick) but as well experiment with diffrent shapes - like the one on the right with hole inside - that would give more light. Thats why i think the best solution would be using brep for this definition.
2- Multiplication - biggest problem for me - I don't know how tall the wall would be, what will be the final shape of Brep (brick) and that's why i would like to manipulate this with sliders as well. All the walls are flat (maybe it would be easier to use surface?). As i managed to multiply the bricks easy way i don't know how to gain control over height of the wall - for example that it is 30 bricks high, but has each second row moved on x axis by the distance of 1/2 brick. I tried using Series but with no success. Could you help me with that please?
3 - Rotation - i would like to use image sampler for that so i can "paint" where i want more sun and where i dont need it at all (black and white). The rotation has to be limited to 180 degrees as well. Obviously i didn't get here yet, but i never used image sampler so if you could give me some advice how to use component and how to create such images i would be really grateful.
4 - More of a concept thing - since the connection angles differ from 90 degrees i will have to figure out how to connect the parts of the wall at sides ;).
I would like to ask you for help with the defintion, since i am totally stuck at step 2. I post what i came up with so far. Thank you for your time and help!
PS. I post an image that is pretty similar to one of options i would like to check for my building.

phere with the maximum number of triangles but not much than a defined threshold.
I scaled that mesh just to fit Rhino grid, but it is not mandatory. What is useful, is to scale not uniformly the mesh (Scale NU). It could be done after cellular modifier applied or before or before and after. The 3 options are possible in the script. If you don’t need them just put 1 in scale sliders.
Ellipsoid mesh is the populated with points, I put 2 independents populations to randomize a bit further. For each vertices of the mesh the closest distance from the populated points is calculated.
Here is an illustration in color of this distance.
This distance is then used to calculate a bump. If domain for bump is beginning with negatives values to 0, it carves the mesh. Instead it bumps/inflates it.
Some images to illustrate the difference with populating 100 points with one or two populations.
Here some images to illustrate the application of scale before carving or after.
Next phase apply noise. At the moment I don't find it good.…

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!…
d simulate the bending process of a flat stell sheet in order to get the same shape. This can be really interesting so we can evaluate the material beheaviour, the deformation on the cross section a
nd explore big deformations in mecanics analysis of materials.
I am not a mecanical engineer nor a civil engineer, I´m an Architect and my interest is the construcction method and extracting the necesary information to consider fabricating the project.
I´m having conceptual challengings on the methodology for this simulation, so I will post a small overview of what I`ve done.
1.- Understanding the Geometry.
This is a sclupture by the Venezuelan/Hungarian/German artist Zoltan Kunckel (KuZo).
The shape is achieved bending a pre water cut square sheet of stainless steel. After bended manually, the different lashes are pulled on the opposite direction. New curvatures are produced after all is deployed.
2.- Reproducing the Shape digitally.
Using Karamba I built a definition to reproduce the produced by physical stress. This model served to find deformations that occur when a set of loads are applied to a mesh. Following this process will allow us to find a coherent and more natural cross section so then we could re-shape simulating the bending process of a piece of ductile material.
3.- Discretizing curve
Reducing the model to its simplest element is a key aspect of finite nonlinear analysis. Once our shape is already defined we can divide its principal characteristic of its principal given curve.
At this point I have already found the desired curve.
I Think the better strategy to simulate bending the steel sheet into this shape, is rationalize the curve and divide it finding the tangents one of the curve that compose this sort of parabola. bur i don`t know how to parametrize that in GH.
Please. If someone have a better Idea about this process I`ll glad to read sugestions.

rrect, the heat balance of a zone is always 0 = Qcool/heat + Qinf + Qvent + Qtrans + Qinternalgains + Qsol. These parameters also correspond with the readEPresult element. However, if i sum up these values there is a slight deviation.
The deviation is greater during daytimes and in winter, suggesting it has something to do with the heating values.
Attached you'll find an image of the energy plus outputs that I use and the resulting -.CSV file that I constructed. In this you'll see that the balance does not add up.
Am i missing some energy flows?
Thanks for the help.

new component "OSM 3D roof"):
2) Simplified 3D roads can be created by using the network of OSM polylines (through new component "OSM 3D road"):
3) 3D forest.Up until now, Gismo supported generating a single 3d tree whenever such tree was present in openstreetmap.org database. Now it is possible to generate 3d trees in forest areas, by randomly positioning the 3d trees (through new component "OSM 3D forest"):
4) Boolean 3d shapes.Gismo's "OSM 3D" component generates shapes as parts: for example, if a building has irregular shapes across its height, they will all be created individually. Trying to merge them with Grasshopper's "Solid Union" component can sometimes fail.New Gismo "Rhino Boolean Union" components tries to overcome this issue by using a much better Rhino version of this command.
5) Library of common GIS color palettes (gradients).A single component containing 22 of the common color palettes used in GIS applications as ArcGIS and QGIS. For example: elevation, aspect, precipitation...
6) Url to location.Thanks to idea by Alex Ng, it is possible to extract location from a link of the following map websites: Openstreetmap, google maps, bing maps, wego.here, waze:

surfaces resulting from 'SrfSplit' so they could be sorted to discard the largest one (in cases where a Voronoi curve crossed a surface seam, there are three resulting surfaces, not just two) and
The centroid for each Voronoi curve/surface required for scaling the holes.
So I created a cluster called 'pLen' which returns the perimeter length of a surface (the sum of the lengths of its edges) to be used instead of surface area for sorting (#1). And used another cluster I have called 'PtCloudCntr' that returns the mathematical center of a point cloud (#2). Both of these clusters are extremely fast and worked fine together as a replacement for 'Area'.
But in the process, I discovered and fixed a couple things:
In those cases where Voronoi intersection curves cross a seam in the "Primary Surface", I joined the two pieces together before creating the hole - eliminating the seam from the results!
Somehow the optional 'Bounding Box' used by 'Voronoi³' component got lost (oops) so it was cutting off the results bounded by the random points instead of the "Primary Surface". Fixed that and found later that in some cases (the 'Revolve Srf' in this code), it works much better to double the size of the 'Bounding Box'. Since there is no penalty for this, speed or otherwise, the larger box is used for all surfaces.
The results are MUCH BETTER than before. Surfaces don't lose their edges, holes aren't corrupted by seams and the code runs in roughly 2/3rds the previous times (30 seconds instead of 45 seconds for 438 holes as in prior code). For 100 holes, it takes only six to eight seconds to change the "Primary Surface" and get a new holed surface.
This 'Revolve Srf' is substantially smaller in scale than the other surfaces and due to its apparent complexity(?), it starts to degrade in quality with "large holes", i.e., less than 100 holes:
