onents (radiation, sunlight-hours and view analysis) which let you study the effect of the orientation of your building and the analysis result. When you come to a question similar to "what is the orientation that the building receives the most/least amount of radiation?" is probably the right time to use this component.
HOW?
I'll try to explain the steps using a simple example. Here is my design geometries. The building in the center is the building to be designed and the rest of the buildings are context. I want to see the effect of orientation on the amount of the radiation on the test building surfaces from the start of Oct. to the end of Feb. for Chicago.
First I need to set up the normal radiation analysis and run it for the building as it is right now. [I'm not going to explain how you can set up this since you can find it in the sample file (Download the sample file from here)]
Now I need to set up the parameters for orientation study using orientationStudyPar component. You can find it under the Extra tab:
At minimum I need to input the divisionAngle, and the totalAngle and set runTheStudy to True. In this case I put 45 for divisionAngle and 180 for the totalAngle which means I want the study to be run for angles 0, 45, 90, 135 and 180.
[Note1: The divisionAngle should be divisible by totalAngle.]
[Note 2: If you don't provide any point for the basePoint, the component will use the center of the geometry as the center of the rotation.]
[Note 3: You can also rotate the context with the geometry! Normally you don't have the chance to change the context to make your design work but if you got lucky the rotateContext input is for you! Set it to True. The default is set to False.]
You're all set for the orientation study, just connect the orientationStudyPar output to OrientationStudyP input in the component and wait for the result!
The component will run the study for all the orientations and preview the latest geometry. To see the result just grab a quick graph and connect it to totalRadiation. As you can see in the graph 135 is the orientation that I receive the maximum radiation. Dang!
If you want to see all the result geometries set bakeIt to True, and the result will be baked under LadyBug> RadaitionStudy>[projectname]> . The layer name starts with a number which is the totalRadiation.

her people) a tremendous amount of time creating them by hand. Dog Treat was far from perfect, however it was good enough to use almost daily.
Three years is a long time. Since 2016 my Gh knowledge has expanded and I’ve seen how dodgy some of the scripting is. With this in mind I started work on a new build. Many things have been tweaked and some things have been rebuilt from the ground up.
Everything has been designed to be leaner and be a general solution to the problem of creating dog bone corners on geometry for quick, efficient and safe CNC fabrication.
Some of these things are:
Adding prompts about user geometry to make them aware about open curves, varying curve heights and if their geometry had been altered (mostly removing unnecessary points on curves).
Smooth Transfers. If you’re in a rush and need to speed through cutting, smooth transfers mean that a lead in geometry is now created alongside the actual dog bone arc. This means the router bit doesn’t have to come to a minute stop at every corner. This is turned on by default.
Acute Angle Condition If the angle between the two curves adjacent to a dog bone point is acute, previously the dog bone corner was useless. This was because the distance between the end points of the dog bone arc were less than the diameter of the router bit. There are many ways this condition could be addressed. I chose to circumscribe a larger arc based on the original angle between the adjacent curves. While it removes more material from the corner, it minimises tool wear and any potential for material to burn.
Single Curve A single curve can now be input into Dog Treat. It will be output with both internal and external treatments.
I’ll continue to update Dog Treat as the need arises, it’s become somewhat of a hobby now. Maybe one day it will become part of a Plug-in… once I learn to code it though!
Happy Treating!
Hi Everyone,
Here's a tool I've been working on for the past 4 months or so in my free time. It's a dog bone corner generator, however it's a little different to some of the existing ones. It's designed to be used for large amounts of geometry and as such, it avoids using any curve boolean operations that are computationally taxing. You don't have to split your curves up into internal and external lots either, it works it all out so you can be lazy. I've also incorporated Lunch Box's Object Bake Component for a one click operation that bakes geometry back out to Internal and External profile layers.
Let me know how it goes, will update where necessary.
Best,
Darcy

thought that architect's love for drawing comes from the necessity of translate abstract ideas into built 3D reality, and the technology behind that 2D representation has not evolve so much until some decades ago. Our teachers come from that times: times when computers try to find their place in the reality representation world. If you try to imagine that people that have always drawn with pencils adapting to this new tools...some become fan of new methods, other just keep the old fashion workflow (like Andrew said in the article, Schumacher VS Graves)
We've bear (at least Andrew and me :P) in 80's with first video games, computers (I still remember my old x286 with 1Mb RAM and 20Mb of HD and that MS-DOS interface)...New technology was natural for us...But there is a big difference between traditional drawing and new computer aided tools: the learning curve. To draw you only need to take a pen and put over a paper (that interface is understood by children easily) , but traditional computational tools (new touch interfaces are out of this group) are based in a complex logic and environment that is not easy to understand for some people.
In the workshops I'm teaching in, I try to put all that tools (new and old one) in my students hands and motivate them to mix and use them together (Andrew knows a little bit about that :P). Why not to make a lines sketch with GH and then print it and render with some markers?; the last step could be scan the result and enhance it in Photoshop adding textures, vegetation, some background...There are no rules, only a bunch of tools to explore and use to develop your ideas, evolve and finally represent them.
I bet to the touch interfaces (with some augmented reality sauce) like that one that will be able to blend both worlds, analog and digital, offering that fluidity and natural interaction that Grave miss in digital tools. And our generation attached to this "not natural" interfaces will need to change its mind and adapt to that new and amazing interface that our children will love.

After that I used cocoon. Here the parameters I used for the Brep and curve. So The Brep was offsetted.
The model is 80 unit height and cell size is 0.2 so roughly there are 400 divisions in Z. If cubic it will give 6.4 millions of cells. To my point of view it is important to choose well the cell size in order to have not hundred of million of cells. Here 6 millions was usable. The general thing with Cocoon is alwas to test it on small objects first.

mers considering extreme sports reject mainstream retailers and like to check out small stores rather of at chains plus malls. Several smaller retailers discuss trends in sports shoe sales. http://skateszone.com/
Though athletic shoes and sports stores and from doorways retailers have reported somewhat uptick in footwear sales due to the increase in extreme sports, the particular beneficiaries inside the trend are independent surf and skate niche stores.
Some West Coast surf and skate shops stated teenagers and even more youthful Generation Xers are not only rejecting traditional sports, but they're also shunning mainstream retailers and malls meant for smaller niche shops transporting hard-to-come-by brands.
Eddie Miyoshi, district manager at Atomic Garage, a 3-store chain situated in Gardena, Calif., stated the soaring recognition of skateboard footwear has boosted the retailer's total footwear business 20-thirty percent this year, rather of '95.
Skate footwear presently represent 80-90 % of Atomic Garage's shoe sales, while couple of years back, Dr. Martens and Timberland drove the retailer's footwear business.
Like many retailers, Miyoshi pointed to Airwalk since the trend's catalyst.
However, if Airwalk broadened its distribution to larger chains, which are frequently located in malls, only a few skate shoe customers adopted. Rather, many youthful males have switched for your skate shops for additional elusive brands like Etnies, Duffs, and Electricity Footwear by Circus. By refusing to market bigger retailers or sports stores, these brands are increasing their cachet among youthful consumers.
"Kids don't want stuff which have been within the shops,In . Miyoshi added.
Searching ahead, Miyoshi forecasted skate shoe sales will remain strong through spring '97 provided "the [hot] vendors don't auction other [non-particularly shop] retailers."
"Skaters and non-skaters are rebelling against mainstream retailers so on to surf and skate shops for many looks," echoed Mark Richards, co-online sources Val Surf, a 3-store chain situated in North Hollywood, Calif. Soaring sales of skate footwear have driven total footwear receipts up 25 percent this year rather of '95.
"The quantity of that increase might be connected while using exposure of maximum games? I am unsure. [Skate footwear] may also be actually the think about the moment,In . Richards acknowledged. And in relation to getting this right look, youthful customers can be very picky.
"Skateboard footwear is a huge category for people, but we're not able to own the brands, Etnies, Duffs, Electricity and Nice, simply because they won't sell us," stated Mark Anderson, buyer at Chick's Sports, a six-store chain in Covina, Calif. "We have people coming every single day requesting them." Consequently, skate footwear have consistently ongoing to obtain about 5 % of Chick's overall footwear business. http://skateszone.com/the-top-8-best-skateboards-for-beginners-reviews-2017/
Nonetheless, some outdoors, niche sports and sports retailers are noting the growing recognition and coverage of maximum sports will receive a modest impact on footwear sales. Trailrunning footwear and approach/outdoors crosstrainers will be the two groups benefiting the very best inside the recognition. Like the skate shoe business, some retailers realize that styling instead of function frequently drives sales of individuals footwear.
"At this time the merchandise is a lot more visual than function," stated Chet James, gm of Super Jock 'N Jill, Dallas, speaking about trailrunning footwear. Still, James noted the current hype over adventure sports helps draw more customer traffic. "The marketing campaigns and media help bring growing figures of people in, nonetheless they frequently occasions day an issue that increases results on their own account,Inch he conceded.
John Wilkinson, executive vp inside the 85-store chain Track 'N Trail, Eldorado Hillsides, Calif., stated the shop has "seen some activity in approach footwear," but he requested the amount of consumers depend in it commercially sport. And, instead of accelerating total footwear business, Wilkinson speculated elevated sales of approach footwear and trailrunners are gnawing away at traditional hiking shoe and boot volume.
But Dan Bazinet, president of Overland Exchanging, a 34-store chain situated in Westford, Mass., believes the company-new looks have breathed existence for the wilting hiking boot category. "[Approach-type footwear] don't represent the lion's participate the hiking market, nonetheless they have elevated the hiking business and provided us extra sales," Bazinet stated.
He designated Timberland's Treeline Series and Rockport's Leadville line as strong performers. Unsurprisingly, he noted the company-new looks are attractive to youthful consumer base than traditional hikers.
For that month of June, sales of men's hikers were up 49 percent at Overland, rather of June '95, while sales of women's hikers were up 17 % for that month. Bazinet also attributed elevated sales that shops walked inside the hiking business, departing that business for that specialists.
Some retailers draw a good example concerning the hiking boom of two yrs ago combined with the current extreme sport phenomenon. "Plenty of bigger chains will get a specific percent in the industry while [extreme] sports remain a fad because they are selling cost-point type gear," described Steven Carre, assistant hard goods buyer at Adventure 16, a six-store chain situated in Hillcrest.
"However individuals [true enthusiasts] will say `we need real gear' and may shown up at us. That will help us after a while. What Size Skateboard good for an 3 4 5 6 7 8 9 10 11 12 13 14 year old

In the visualization, points is an interesting option. It's a matter of aesthetics I guess, I go with surfaces :) Also what you can try is selecting Filters -> Slice (you can also find it in the icons above the pipeline viewer), in the Slice options below the pipeline press Z normal and on the Z coordinate press some height relevant to the buildings (e.g. 1.75m a typical human scale). That would show you the flow around the buildings on that height. Experiment with selecting other normals and values. Keep playing with the filters there's some cool things in there. Also you can check out the mailing list and extensive paraview documentation.
Concerning the errors I apologize because I just downloaded your case.
It appears that the decomposeParDict is not included in the system folder. I am not sure if this is due to BF not going through the whole workflow yet or an ommission on our side. Please feel free to add it in Github. I will also note it down and pass it to Mostaph to check. In the meantime please find attached a VERY detailed decomposeParDict file. I took the liberty to set it at 4 processors (the numberOfSubDomains value) and also selected (that is uncommented) the scotch decomposition method. It's the easiest method to use since it is automatic and doesn't require any more inputs on how the domain is decomposed on the x,y,z directions (which would require you to change values in the attached file).
Now, the different folders created are simply snapshots of the current solution at the specific timestep. To control how often the solver is saving change the writeInterval number in the controlDict file. You can also change almost all these values on the fly, while OF is running.
Finally, concerning the other errors of parafoam it seems somehow parafoam is reading the intial condition names instead of actual results from the solution files and it doesn't like it.
Does this happen only when you open the case (i.e. at 0 time) or does it also happen when you move to an other timestep?
Also, are you using paraFoam, paraview or the paraFoam -builtin method?
The extension of the paraFoam file seems to be .foam which means you are probably using the built in viewer. That might be the issue but I'm not sure.
Can you try running paraview, navigate to your case folder, open the .foam file and see if there is still an error?
Also, if it isn't much trouble can you zip one of the time folders and attach it here? I'd like to take a look at what's inside to check against what the error report says.
Once again thanks for testing!
Kind regards,

mmon.sdk ,but i herad its used in rhino5.
or example: the book grasshopper primer second edition ,page 98
i dont know what is the "doc.absolutetolerance" and where i can find about it....i dont kow it should be a class or a fuction,i tried to search the rhino4. net sdk,i cant find it ....maybe its my searching problem.
but according to the grasshopper primer, i indeed know many kind of Variables,many functions,basic structure, loops, and conditions,and what is onutil.xxxx and rhutil.xxxx.but i found all this imformation is not helpful enough to me when reading the examples downloaded from many disscussions.when i found a new variable or new funcion,i dont know where i can find the introduction about them,such as the upper coding:"doc.absolutetolerance".i tried to use the auto complete such as
dim xxxx as oncurve
xxxx. to find the class oncurve's funtions and variables ,but its too uneffcient.
-----------------------------------------------
And,i dont know the difference between the components vb script and dotnet vb script....
because i found when i type onutil. the auto complete has noting appear...and the variables declaring is not the same. in vb script dim xxxx as curve but in dotnet vb script its dim xxxx as oncurve,which is the same as the grasshopper primer teached me...but i guess.... the vb script component is just like the rhinoscript(not the same),and the dotnet vb script is more powerful than it. am i right?
------------------------------------------------
at last i dont know these.
Imports System Imports System.IO Imports System.Xml Imports System.Data Imports System.Drawing Imports System.Reflection Imports System.Collections Imports System.Windows.Forms Imports Microsoft.VisualBasic Imports System.Collections.Generic Imports System.Runtime.InteropServices
when i search google about them,the introduction about them is too professinal for me to understand......i just want to know what i can do by using them ...

sorry for disturbing you so much!!!

n to finding a concave contour polyline (which is in general what you need). In your case each contour section contains a series of points of which you do not know the order and you need to sort them so that by connecting them you find the contour. This is fairly easy to do when the contour is convex (basically you find the average point then calculate the vectors from the average to the points and sort the vectors by angle - sorting the points by the same angle gives you the right order for the contour), but generally impossible to find uniquely when the contour is concave (PS: convex means that, for ANY 2 points inside the figure, a straight line connecting them doesn't intersect with the border curve - i.e. circles, ellipses, rectangles, triangles - concave shapes are a star, a crescent moon, an arrow, a boomerang, etc.).
The problem goes like this: given a generic list of points:
Each of these configurations for a perimeter equally fits the above:
Laurent already went for another possible solution, the stochastic approach (by subdividing the connecting lines), I slightly adjusted a few things over his solution:
namely, I added a rounding option to adjust for some weird tolerance issues (some points that should be at Y=80 were at Y=79.99998 or something) and a more straightforward solution to group them by section plane using sets logic. This, coupled with alpha shape, gives a quite good approach, still very coarse in terms of results but that depends on the sampling resolution of the field (i.e. number of height sections in which you calculate the metaballs) and sampling length of the connecting lines.

Diffraction , I left it, how it is.
For the unusual issues that comes in the image source component, so, is it something strange? But, I still have the same issues when I sets any integer component (single or multiple) in the “reflection order” of the image source component, in the “image source order” in the ray tracing component, and again, when I connect the output “Direct sound data” of Direct Sound component in the Energy Time Curve.
Do I wrong something with the integer component? I used it already in the first parts, for sets “grasshopper layers”, in the “Scene” component, but here it works. Should I start with a new file?
For the multi-object optimization, thank you for all suggestions. Yes, I red PHD thesis work of Tomas Mendez and the article “ EDT, C80 and G Driven Auditorium design” and still others. Thank you to all these articles, I decided where to focus my thesis.
I understand the potential of Multi-object optimization, and problems that I can finding without using it. Actually, in the beginning of my thesis, I tried to jet in contact with the Politecnico di Torino, but was not easy because I’m not a Politecnico student.
Here, in University of Florence (Building engineering), there isn’t a department or someone that is already familiar with these field of study, so, as you can image, for design my thesis, I can confide on online resources. So far, my Professor suggest me to begin with a Nonlinear Global optimization like Galapagos, and only after see the multi-object. In this way, step by step if something doesn’t work is easier to understand way and where something is going wrong: if are problems due to the setting of the programs, because we are not practical about these, or if there is a wrong in the simulations or in the algorithm and ect.
Do you think is a good way for go on?
Thank you very much,
Kind Regards
Giulia
