he picture (4).
Previously, I had a problem with generating intersections between the two directions of the beams, but a colleague helped me by extending beams, so there was no problem with lines of intersection. But this solution has generated curl (5) at the highest vertex geometry, which I ignored in order to repair it before printing, perhaps this mean my problem with my beam spread properly. Only when the beams is 19, does not jump no problem, but I still can not distribute them properly.

y interesting and smart way to construct surface. I tried some experiments out using a similar idea - take a developable surface which has a series of holes cut through it now offset that surface and unroll both of them, once both have been cut out insert a dowel into the holes (the dowel represents the offset distance). In the end the shape is recreated via tension and in that way there are some similarities. With your concept the thing I have trouble figuring out is how do you cut the variable angle kerfs. Are you using a 5-axis swarf cut, a cnc panel saw - how do you control this? It would be great to have a set of constraints which limit the number of possible angled cuts - these limits would equal the number of v-groove bits you have in the cnc - and then you could just cut the lines with the programmed tool which matches the given angle. Or maybe I am completely wrong, now I think I am wrong, about the execution and you are only changing the gap between each kerf and the angle of the side wall stays constant.
Anyway to answer your question catia can analyze the characteristics of a piece of formed material (this analysis is usually applied to sheet metal and to design forming tools)it's just a matter or defining the material to match that which you are using. Another possibility although not as numerically clear is using a simulation tool like Maya cloth or Virtools. I know this maybe less likely but you can define all sorts of materials in Maya and then simulate their behavior under numerous forces and constraints. I think it would work it's just how do you extrapolate the values Maya needs and then correlate them back into the cloth parameters. Once it yields the final formed mesh then further analysis could be performed in cosmos, ansys, or catia.
I have one other suggestion. In solidworks if you perform a lofted bend on a sheet metal part and then generate a flat pattern it creates a large set of bend lines representing how to perform the bending of an unusual shape using a metal brake. It seems like those bend lines could be machined with you technique to create lofted forms instead of extrusions.
What materials seem to work best so far, have you only been using wood (the purple stuff is probably not wood)?
If you are ever in Los Angeles I have a shop with a 3 axis and 5 axis router, a large vacuum bag, and all the other things to experiment on this and would be open to this.…
which needs to go in the first line only.
Each value K is one element of the knot vector
XYZ is an individual control point. Each point gets its own line/string in the output list
R is the weight of the XYZ point defined in the same line
I can get all these data into separate lists easily enough using the buttons etc. But getting them into the proper order and moving stepwise down the data to generate the desired output string list is eluding me so far.
My thought is to make an array of columns.
Column one is a list of knot values.
Column two is a list of X values.
Column 3 = list of Y values
Column 4=z values
Column 5 is weight values
etc
The idea would be to read the first value in each list into a list of five elements, then make a string out of it. The second value of each column into a separate string on the next line, then the third value from each column into the third string in the output list and so on.The last few values in the output list will contain knot vector elements only, as there are more of these than there are control points. Some of these curves are very long, with many control points, like hundreds and hundreds.
It seems I should be able to pull the lists of interest and combine them into a tree somehow; so far all I have been able to manage is to get them into a single list by starting with control points, then weaving each list of interest successively into the growing list. I'm thinking I need to get the list for each parameter into an individual branch, then read a path across the branches at each index value. But I am missing something about the terminology. I have watched a few videos and it makes sense when people are pulling nested geometry out of models, but this is a little different. More of a data management issue. I'm sure if I wrestle with it I will get it, but it may not be pretty. Any pointers appreciated. A couple of approaches are attached. Not sure whether to loop a list subset through the data or do something else. Thanks,

e in Euclidean space then the distance metric can be discontinuous:
Discontinuous means that a tiny change in input may result in a large change in output. Observe the image above, we start measuring euclidean distances from point A. At first the process appears to be continuous. We measure at distance b and we get point B. We increase the distance slightly to c and we get point C, which is very close to point B. We increase the distance slightly again to d, but now suddenly we're in a completely different location. This jumping behaviour can mean that certain questions (such as: "how do I divide this curve into 4 points, all equally far apart?") do not have an answer. It could be possible for 3 and 5, but not 4.
Another problem is that there may be multiple solutions. In the image above the point D isn't the only point that is d units away from A and coincident with the curve. There may be any number of those points depending on the shape of the curve, the location of A and the value of d. And of course once you have two (or more) solutions, you can have two (or more) answers. Then each of those solutions may yet again have more than one outcome for the next point in the chain and before you know it the question you asked has 35295 different answers and good luck trying to find one you like.
Now of course sometimes it is possible to answer your question unambiguously. I made a solution that uses Galapagos. It's pretty slow, and it'll get slower the more segments you want:

he Summer in the City program, part of the Portland School of Architecture and Allied Arts (an extension to University of Oregon).
Using both Grasshopper and the Firefly plug-in, this workshop will focus on the design of innovative facade prototypes that are configurable, sensate, and active. Students will become familiar with the terminology used in interactive facade design including an overview of hardware (ie.sensors, actuators, and programmable microcontrollers) as well as software interfaces terminology. We'll learn new prototyping techniques and develop digital and physical models which can respond to a plurality of environmental and user driven forces. This workshop will take a hands-on approach, and you will walk away with the ability to build your own custom electronic circuits (using the Arduino), as well as create interactive simulations and models.
This course will primarily focus on physical computing techniques. Unfortunately, given the time constraints of the workshop, I will not be able to provide an extensive overview of the Grasshopper interface (it is suggested that participants have some familiarity with the Rhino/Grasshopper environment). There are many great online resources to get you up to speed relatively quickly if you are new to this software. This is a good place to start.
The course will be held at the School of Architecture and Allied Arts in Portland, OR. The date/times of the workshop are as follows:
Friday July 19, 5:00-7:50 P.M.
Saturday July 20, 9:00 A.M.-3:50 P.M.
Sunday July 21, 1:00-3:50 P.M.
If you are a designer, architect, or anyone who is interested in learning about the digital tools and technology trends that are revolutionizing design today, this workshop is for you. Make sure to click here to find out more about registration and enrollment in this exciting new workshop.…
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

http://www.pilkington.com/) dominates the planar market. Charges "around" 1K Euros per m2 for a "plain" system. Personally in bespoke projects I design my own stuff but due to economies of scale ... they cost a bit more (but they look far more sexier, he he) . On the other hand only in a bespoke project I could dare to suggest such a solution (for a large scale building we are talking lots and lots of dollars).
3. Several scales below (aesthetics) you can find static alu systems (either structural or semi-structural):
Or hinged systems (either structural or semi-structural) capable to adapt in contemporary double curvature facades/roofs/envelopes/cats/dogs etc etc ... pioneered worldwide many years ago by my best friend Stefanos Tampakakis (everybody in UAE knows that genius man: http://www.alustet.gr/company.html):
4. With the exception of some paranoid things that Guru Stefanos does for Zaha these days we are talking about planar "facets" (obviously a triangle is such a planar facet). The current trend is: the more edges the better (humans excel in vanity matters). But achieving planarity in, say, quads (like yours) it adds another "restriction" on what you are doing. Until recently Evolute Tools Pro was the only answer. But right now ... well let's say that in short time you'll be greatly surprised by some WOW things in this Noble Forum, he he.
5. MERO (and obviously custom systems) can adapt (at almost no extra charge) in anything imaginable. But in a bespoke building ... well.. you know ultra rich people: they don't want MERO anymore since "everybody" does MERO solutions. Vanity, what else?
6. Smart Glass would become a must in the years to come: Eco-Architecture MUST dominate everything you do. On the other hand spending millions to do some extra WOW stuff (Vanity) ... it doesn't look to me very Eco-Friendly/Whatever ... but let's pretend so, he he.
7. I'm Architect but a bit different from the norm: for instance I smoke cigars (highly politically incorrect stuff) I always talk openly (ditto) and I ride lethal bikes (ditto).
may the Force (as always the Dark Option) be with you: go out there and kill them all.
