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.

So with this there was an intersection with the Brep volume of the chair and the lattice.
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

I figured that connecting points and lines kind of works (point and line input AB command) but the line length changes when I move a
point. What I want to be able to do is to move a point and drag others but keep
the line segments constant, just as a real net.

ehow acquire different settings/are calculated differently. Appears at random “rows” of points, sometimes it all works fine, so I need to do a series for the error to show. See images below.
In the Ladybug fly run the VT of the window changes.
It’s taken me a day and a half to track this error down. Phew.
I get the same error on two different comps.
What is causing this? Does anyone get the same error? Images below created with RADquality set to 2, and 7 cores. Fiddling with Radsettings dont help, I think, except error goes away with very low ab.

d the fact that one pipe goes out and one goes in, that the surface normal direction is opposite for the two surfaces? Based on an earlier thread, you should know why by now. The two curves have opposite directions (again!); see the white arrows using Rhino 'Analyze | Direction'?
As before, you can fix that by flipping one curve to match the other. HOWEVER, you connected your curves directly to the 'Divide' components instead of using 'Crv' geometry params - bad form. And as before, you "fixed it" by reversing the list of starting points ('S' input to 'BiArc'). Better like this - 'Crv' params are internalized, no need for Rhino file:
Well, well! That didn't fix the opposite surface normals after all! Trust me, though, using geometry params and being conscious about matching curve directions is "best practice". But I haven't lofted 'BiArc' curves for awhile, it's late and I want to move on. OH! I just noticed that you reversed the 'Z' direction for one half of the 'BiArc' - that explains it:
Moving on... You've basically got it, though I would do it differently - same result, like this:
I haven't really explained surface normal vectors - can you figure it out from here? One more little wrinkle (Normal_2017Mar17b.gh):

ported to Rhino and "set" in Grasshopper, i trim both surfaces from their rectangular bases so that when sDivide is used it creates and distributes the same number of points on each surface.But heres the problems: a) if i use the "trimmed" surfaces with SrfGrid it errors warning: "A point in the grid is null. fitting operation aborted".I'd learned this was caused by "nulls" replacing position Data Items when the rectangular grid(surface base) was trimmed away. So i used Clean Tree which worked removing all nulls, then Shift Paths\Flip Matrix to create line-endpoint pairs for Polyline\Evaluate Curve. I Flattened the last Flip Matrix placing all data items in one source for SrfGrid, like in the working Untrim\CopyTrim definition.This time,.b) SrfGrid errored with: "The UCount value is not valid for this amount of points",.So, i substituted a 356 value, numeric Slider in the Addition B param., and tested its range until a valid UCount was found. Then SrfGrid fitted a surface thru the points, BUT,d) those SrfGrid surfaces are extremely deformed even thought the points preceding it from Evaluate Curve are accurate,SEE: def: "3b-RGH_SurfaceBlend.gh",AND,.a2) if i use Untrim with CopyTrim then SrfGrid works, but since the Jokers limbs WILL be in different surface positions then the blends between the Arm (for example) will rise from its relative FLAT position on the untrimmed Source surface to the Arm on the Target surface, rather than morphing from the Corresponding Arm position on the Source surface,. ..see def.: "4-RGH_SurfaceBlend.gh"So please let me know,..1) how to produce accurate surfaces from SrfGrid in def.: "3b-RGH_SurfaceBlend.gh",. ..(NOTE: BOTH these def's contain 2 indentical, "internalized" surfaces, but if def. 3b can be made to work it will also work with Dis-similar surfaces)2) which component to use or how else to determine the correct UCount value for a specified amount of points(ie:155), re: SrfGrid error: "The UCount value is not valid for this amount of points",.3) how else to force SrfGrid to work with Trimmed surfaces?, AND,..4) how to force intersurface, point-blend correspondence lines: Polylines(PLine) to be connected between correctly! correponding positions (Limbs) on the surfaces?,

nowledge, tools, materials and machines. The Clusters provide a focus for workshop participants working together within a common framework.
Clusters provide a forum for the exchange of ideas, processes and techniques and act as a catalyst for design resolution. The Workshop is made up of ten Clusters that respond in diverse ways to the sg2012 Challenge Material Intensities. The Call for Clusters is now open to proposals which respond in innovative ways to this year's challenge.
Deadline: September 19 2011

sg2012 takes place from 19-24 March 2012 at EMPAC (http://empac.rpi.edu/) and is hosted by Rensselaer Polytechnic Institute in Troy, upstate New York USA. The Workshop and Conference will be a gathering of the global community of innovators and pioneers in the fields of architecture, design and engineering.
The event will be in two parts: a four day Workshop 19-22 March, and a public conference beginning with Talkshop 23 March, followed by a Symposium 24 March. The event follows the format of the highly successful preceding events sg2010 Barcelona and sg2011 Copenhagen.
sg2012 Challenge Material Intensities
Simulation, Energy, Environment
Imagine the design space of architecture was no longer at the scale of rooms, walls and atria, but that of cells, grains and vapour droplets. Rather than the flow of people, services, or construction schedules, the focus becomes the flow of light, vapour, molecular vibrations and growth schedules: design from the inside out.
The sg2012 challenge, Material Intensities, is intended to dissolve our notion of the built environment as inert constructions enclosing physically sealed spaces. Spaces and boundaries are abundant with vibration, fluctuating intensities, shifting gradients and flows. The materials that define them are in a continual state of becoming: a dance of energy and information.Material potential is defined by multiple properties: acoustical, chemical, electrical, environmental, magnetic, manufacturing, mechanical, optical, radiological, sensorial, and thermal. The challenge for sg2012 Material Intensities is to consider material economy when creating environments, micro-climates and contexts congenial for social interaction, activities and organisation. This challenge calls for design innovation and dialogue between disciplines and responsibilities.sg2010 Working Prototypes strove to emancipate digital design from the hard drive by moving from the virtual to the actual in wrestling with the tangible world of physical fabrication. sg2011 Building the Invisible focused on informing digital design with real world data. sg2012 Material Intensities strives to energise our digital prototypes and infuse them with material behaviour. They have the potential to become rich simulations informed by the material dynamics, chemical composition, energy flows, force fields and environmental conditions that feed back into the design process.
