pproach of estimating wind loads using design codes such as ASCE7-05.
B) Hiring a wind expert to construct a physical model and and calculate wind pressures measured directly from a wind tunnel test.
A) will allow you to derive a site specific wind design pressure based on the height of the building, surface roughness, site location etc. Typically you then multiply this pressure by an appropriate co-efficent in the code for a given building shape.
The other atypical method it to use numerical approaches such as CFD. This approach is not yet accepted due to nuances such as of surface roughness.
Building deflection is again subjective. Doing a modal analysis and getting an idea of the frequency is better. You can increase the frequency by playing about with the building stiffness.
You need to modify the stiffness of the building to get the deflection down. i.e. play about with geometry, add extra members with stiffness, reduce weight, use material with higher elastic modulus etc
If you are getting a 7m deflection for a 400m building then I can right away that is way too soft. That is equivalent to 400m/7m or H/57. You want to be at least H/500 to H/1000 so aim for 80 to 40 mm.
Your wind load seems reasonable at 87 psf for that height of building

oks like all your GH components are disabled? I just tried baking the cone from my earlier code and using that but can't see anything at all.
OH! You had 'Display | Shaded Preview' disabled - why? Now I see that you have 80 X 55 'SFrames', which will be VERY SLOW. I never understood why you abandon 'PopGeo'? But that many points will be extremely slow either way. I won't wait that long.
You're making this way too hard for me, bobbi.
I said early on that it's best to work with a very low count until everything works properly. Solid unions are one of the ragged edges of Grasshopper; slow and prone to failure, depending on the complexity of the geometry (co-planar surfaces, etc.).
Good luck!
P.S. I can see two problems here:
Surface normal is in instead of out.
You didn't 'Cap Holes' on the lofted tubes so they aren't solid "Closed Breps".
I have no clue what you're doing. Do you? :)…
k on forum?
or
B) install from a networked location?
Second question.
If you download from link do you:
A) read the post because you want to see what changes have occurred?
or
B) ignore the post as you are too excited to get the latest version up and running?
Third question.
When confronted by a demanding LOL cat telling you to update software do you:
A) nod approvingly and think "I must do that"?
or
B) freak out and get a sudden urge to eat cheeseburgers?
In all seriousness question three can be omitted.
EDIT: 80 views and only two posters! (thank you Simone and Luis).
I am actually interested in the results

oxes in the most efficient way within boundaries of object and follow the following constraints. The Goal: To fit 125 boxes in the most efficient way inside the total area. Starting Variables: (1) 40% of the Boxes need to be between 60 and 85MSQ. (2) 40% of the boxes need to be between 86 and 110MSQ.
(3) 20% of the boxes need to be between 111 and 125mSQ. The breakdown doesn’t have to be exact to give the script some flexibility. Meaning you can have 41% +39% +20% = 100%.
Constraints:
1. A total MAXIMUM area of approximately 1600M per layer.
2. A maximum of 8 layers for a total of 12,800M per layer. Optimization can make as little or as many as 8 layers vertical to accommodate all boxes. So if script can achieve with 3 levels great. If needed all 8 levels, that's fine too. However, pay attention to next constraint (#3).
3. Approximately 15% of that space on each layer is off limits. (internal area) (blue area in example script) and the shape of the boundary cannot be modified to accommodate box design resulting in jagged lines for the internal area.
4. All generated squares/rectangles must have at least 3m touching an outside border (The Green lines).
5. All boxes must also be touching minimum 1M of border of the blue line.
6. If the boxes generated go outside the green boundary, they must be fillet to maintain the straight lines of the green boundaries.
7. Get as many of the boxes as possible a view towards the dots.
Could any one provide me a method or a way to start, if there are any useful links, please share with me. Thank you!…

re is my problem... I need to arrange Boxes in the most efficient way within boundaries of object and follow the following constraints.

correct:
- the right value in the 0. path {0;77} is the smallest one.
- right value in the 1. path {0;78} is the value which is closest to the chosen value in the preceding path
- ..and so on for {0;79} and {0;80}
but when the paths change their first level, the iteration should start from the beginning:
- right value in the 4. path {1;32} is the smallest one.
- right value in the 5. path {1;33} is the closest to the chosen one in {1;32}.
- right value in the 5. path {1;34} is the closest to the chosen one in {1;33}.
..to be continued.
..this is, what I want to achive in the VB code, I implemented at the beginning of the discussion.
..and this is how I designed the input-parameter of the VB-element:
if someone could help me .. super-great!

Mac due to its versatility , but given this new laptop will be using mainly on Rhino, GH , i have some doubts whether to switch to a window based laptop.
I have a look at some high-end window laptops, Dell Alienware for example, with same specs as MBP and found the price are even more expensive than MBP , about 10-15 %.
With the new Rhino 5 is coming , will Bootcamp be good and efficient enough to run Rhino, GH and some rendering programs?
From my experience i find Rhino and Gh run smoothly on Bootcamp , but never run those programs on window based laptop myself , it's impossible for me to know the differences.
Some say BootCamp only deliver 80% performance of the program , if it's true i would really consider switching to window based laptop.
Any suggestions?
and if you suggest me to switch , what brand should i go for ?
Thank you,

f my list.I don't understand why, but I guess I must be too young user ^^In the original list, i have a path {0;0;0;4} with two index and after the random node, {0;0;0;4} has 88 index.Items are not correct?I would have a comparable structure has the right list on my jpg (photomontage...)How I can do that?Thank you in advance
