he resulting STL file has no problems. I was going to make a 3D print of it but I thought I could make it even more interesting.
When I make a duplicate piece of geometry with reversed curve rotation values and combine the 2 together I get this interesting result:
However, after baking this geometry the exported STL file has a huge number of errors - there are literally thousands of flipped normals, multiple mesh parts, and disconnected triangles.
I have tried lots of things to resolve this and none of them worked: converting to meshes in GH, GH mesh smooth, Rhino Solid Union, Mesh Repair, Align Normals, etc. I use 3D Builder to correct STL problems, but it can't fix this one.
An even more interesting shape happens when I twist the above shape in one direction, and then add it to another that is twisted in the opposite direction:
Of course the STL file for this one is even worse because it just compounds the previous problems.
Is there any way to resolve these problems? My GH file is somewhat messy and perhaps a bit obscure, but I'd be happy to clean it up and share it with anyone who thinks there is a way to get this puppy working.

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

stributes structural supports for a uniformly loaded domain using e.g. the internal energy of the loaded domain as fitness. Here the uniformly loaded domain is represented by the trimmed surface. My genomes are the support positions (green crosses), which are restricted to a set of predefined grid points. I’m currently using an (i,j)-coordinate indexing for these grid points (illustrated in the viewport just below) as opposed to a sequential , “one-dimensional” numbering (illustrated in the viewport further down).
(i,j)-indexing systemAltenative, sequential indexing system
The support positions are computed by two gene pools; one governing the i-index, Gene List {i}, and one governing the j-index, Gene List {j}, of each support. The value of slider 0 in Gene List {i} is paired with the value of slider 0 in Gene List {j} etc. and the amount of sliders corresponds to the amount of supports. The screen shot below depicts the slider constellation corresponding to the support distribution depicted above. Unfortunately the j-index represented in the sliders needs remapping as the number of j-indices vary for each i-index (horizontal row of grid points). With the current setup I have 12^6 x 9^6 = 1,6 x 10^12 different genomes. If I were to use the sequential, “one-dimensional” numbering, I would only use one gene pool with sliders ranging from 0 to 76 meaning that remapping could be avoided and thereby having only 76^6 = 1,9 x 10^11 different genomes.
So, my current genome setup causes a bunch of issues related to the Evolutionary Solver: Remapping Changing one of the j-index sliders, will not necessarily change the related support position but it will still facilitate another genome to be calculated by the solver. (This problem could be eliminated by using the sequential, “one-dimensional” numbering)
Switching slider values around If the values of e.g. slider 0 were to be switched around with the values of slider 5, this again would yield a new genome but an identical solution. (This problem cannot be eliminated by using the sequential, “one-dimensional” numbering)
Coincident support positions Two or more supports may be located in the same position. (This problem cannot be eliminated by using the sequential, “one-dimensional” numbering)
I find it impossible to imagine the fictive “fitness landscape” of this problem and not only because of the multidimensional genome characteristic but just as much because of these listed, intertwined peculiarities. I’ve tried running the Simulated Annealing Solver as well, but my experience is that the Evolutionary Solver yields better results. To my awareness, the solver uses some kind of topographical proximity searcher. This is why, I think that the solving process itself benefits more from analysing the (i,j)-index system, in which neighbouring grid points hold more uniform topographical information than the sequential, “one-dimensional” numbering, which might have big ID-numbering gaps between neighbours. Have I understood this correctly?
Cheers…

During the intense ten-day workshop of the AA São Paulo Visiting School 2014, advanced computational design and digital fabrication will be used to generate speculative new architecture models in the creation of a ‘liquid design’ that can mediate multiple-scale flows. The workshop will explore the redevelopment of a bordering territory along the Marginal Rivers of São Paulo, where in the 1960’s, much of the water-system was disastrously canalized, causing problematic flooding and the creation of ill-conceived residual post-industrial riverbanks that are inhabited by monolithic, large-scale programs such as sports centers, distribution centers, mega-stores and a convention center. The Visiting School São Paulo will work on bringing a new urban life for these sites by redefining the existing macro-architectural typologies along the river with micro-scale interventions that can introduce new flows of urban street culture. Specifically, the workshop will focus on the reinvention of the large-scale market distribution center, CEAGESP (Companhia de Entrepostos e Armazéns Gerais de São Paulo), to introduce programs and structures that could mediate a new movement of people, commerce, and environmental forces using parametric design and fabrication. Students can choose to work either at the larger architectural scale or at the scale of the shop-front display, bringing a new contemporary interface between agricultural production and consumption.
-Teaching team The teaching team will include lead tutor Hart Marlow of su11 (www.su11.com) who specialize in advanced digital design, and local-based architects, to promote innovative strategies informed by local political, economic and environmental issues. -Computational skills
The workshop will teach advanced digital modeling and parametric design skills and rapid prototyping software: no previous experience is needed. A group of specialist computation tutors will conduct an initial skills workshop and continue to assist throughout the workshop to develop the individual projects of the participants. -Digital Fabrication A series of physical models will be built using digital fabrication techniques that will be taught during the workshop, no previous experience is needed.

This is all a sad joke, taking a full day so far. Rhino just sort of sucks for serious work. There's no way I can offer any Numpy/Scipy scripts to clients this way, just impossible. Rhino/Grasshopper Python should come with this stuff, dear developers, or have a simple installer that just works. It comes with math already doesn't it? So why not Numpy and Scipy for serious users?
Upon restarting Rhino, it totally changes behavior and spits out a crazy error upon importing Numpy:
Message: The type initializer for 'NumpyDotNet.NpyCoreApi' threw an exception.Traceback: line 11, in <module>, "C:\Program Files (x86)\IronPython 2.7\Lib\site-packages\numpy\core\multiarray.py" line 6, in <module>, "C:\Program Files (x86)\IronPython 2.7\Lib\site-packages\numpy\core\__init__.py" line 155, in <module>, "C:\Program Files (x86)\IronPython 2.7\Lib\site-packages\numpy\__init__.py" line 1, in <module>, "C:\Users\Nik\AppData\Local\Temp\TempScript.py"
The Grasshopper Python node editor gives the same error. Perhaps I can only import parts of Numpy using "from Numpy import XXXX"?…

of Space, 1984) and specified in (Turner A. , “Depthmap: A Program to Perform Visibility Graph Analysis, 2007), intuitively describe the difficulty of getting to other spaces from a certain space. In other words, the higher the entropy value, the more difficult it is to reach other spaces from that space and vice-versa. We compute the spatial entropy of the node as using the point depth set:
(11)
“The term is the maximum depth from vertex and is the frequency of point depth *d* from the vertex” (ibid). Technically, we compute it using the function below, which itself uses some outputs and by-products from previous calculations:
Algorithm 4: Entropy Computation
Given the graph (adjacency lists), Depths as List of List of integer, DepthMap as Dictionary of integer
Initialize Entropies as List(double)
For node as integer in range [0, |V|)
integer How_Many_of_D=0
double S_node=0
For depth as integer in range [1, Depths[node].Max()]
How_Many_of_D=DepthMap.Branch[(node,depth)].Count
double frequency= How_Many_of_D/|V|
S_node = S_node - frequency * Math.Log(frequency, 2)
Next
Entropies [node] = S_node

not working, then this can be a limitation of Honeybee, not the Terrain shading mask component.You can authenticate the mask shape by using the Udeuschle panorama generator (I used the following Trento coordinates: lat:46.066667, long:11.116667):
Sketchup has a similar plugin for Trynsys3D terrain shading masks.
I gave a reply on your upper questions in here, in component's release topic, so that it would be useful for others users too.
Actually I tried also to create the mask of the mountain using the topography I imported from Sketchup and the Ladybug Shading Mask II component. In this way the shading effect is well noticeable, but the process of creating the mask from such a complex geometry is very slow.
I can make a component which will automatically generate the topography of the local terrain, for a given latitude/longitude, but you will have to wait some time. I am currently doing some repairing around my house and cottage, and I do not have any spare time.Have in mind that depending on the configuration of you PC, you may not be able to have the terrain radius of up to 100 km. While Terrain Shading Mask component actually creates this terrain, it does not add it to the grasshopper document. In your case the terrain will be added to the grasshopper document which may crash Rhino depending on your PC configuration (for example it crashes Rhino on my PC).…
