t worth looking at it seems.
The whole "specification tree" a la Catia where there is a clear child parent hierarchy of grasshopper components would, I agree be great. The ability for constraint based modelling is also great.
However, grasshopper is not a true constraint based parametric modeler like CATIA.
It is also a generative algorithm editor and really shouldn't be compared to tools like CATIA. It could be argued its primary purpose is as a means of providing a visual scripting alternative to traditional text based scripts. I would also argue Grasshopepr itself is very flexible in providing a bespoke blank canvas to set up work flows between different tools such as Catia/excel. This is something I see no other solution out there that can do this.
I love CATIA but however great it is, it is an extremely heavy and unfocussed piece of software. Until Dassault take it seriously as an alternative to REVIT and produce a light-weight version, its dead in the water as regards realistic implementation in the AEC world. 99% of the work benches you don't need for AEC work. It is never going to take off.…
u see around you they lack any zen: that allows the 1% to shine.
2. Each thing that you do/design never dies inside you: Let's call it an "event". The sum of them formulate you as an Engineer. If some "events" are faulty (or worst: shallow) your kaleidoscopic sampling is disturbed proportionally to the sum of the bad "events".
3. "Events" MUST withstand Time: there's nothing worst than fading reasons for doing this or that.
4. "I want" means nothing (anyone wants this or that, so what?). "I did it because" means - maybe - something.
5. Cost (and modesty) should be always your FIRST concern: forget form exploitation(s), new frontier(s) and other similar nonsense > they just yield another pointless waste of resources and guide you gradually into an amoral state of the worst kind: Remember > 1 dollar can save the life of one kid in Africa per day > in this context it's rather hard to justify ... well ... pretty much anything.
6. If you can do anything imaginable this means that you should do LESS other wise you'll find yourself trapped into a rabbit hole that has many entries but not a single #^%^# exit.…
the mesh and 2 curves which represent the problem vector intersections. The VB script:
Dim cell_tot As New List(Of Integer) Dim ray_int As New list(Of line) For i As Integer = 0 To cells.Count - 1 Dim intx As Integer = 0 For j As Integer = 0 To pts.Count - 1 For k As Integer = 0 To sample_V.Count - 1 Dim r As Ray3d = (New Ray3d(pts(j), sample_V(k))) Dim cell_intx As Double = Rhino.Geometry.Intersect.Intersection.MeshRay(cells(i), r) If cell_intx > 0 Then intx = intx + 1 Dim l As New line(pts(j), sample_V(k), 100) ray_int.add(l) End If Next Next cell_tot.Add(intx) Next A = cell_tot B = ray_int
This works with 99% of the vectors but seems to systematically miss some. Wondering if it is a tolerance issue or if I am messing up the code. Screenshot of the geometry, rhino model, and GH defn attached.

ve an adequately low value for vibration. Script all runs fine and matches expected results for a few test cases. Phew. Note that in excel form this calculation runs over 6000 cells of look up's and arrays, it's not a trivial calc that can practically be rearranged to make it work back from an acceptable value.
But in my results I have 99 sets of vibration-acceptable outcomes, which I'd now like to examine to see which one uses the least material in its particular combination of beam thicknesses, slab thicknesses and other stuff to find the overall most efficient system. The plan at the moment is to copy the solver Record over into Excel, extract the %'s for the different variables and post-process the info to sort the acceptable outcomes by weight.
It feels like there must be a better way that avoids taking the data out and having a gap in the parametric thinking. Is there a way to ask Galapagos to give me all (or at least, loads of) combinations for which R < 8 and then test those for the minimum weight? Can I automatically take the winning results from fitness test 1 out into an array of data that feeds into a second fitness test in the same grasshopper space? …

2. This actually means that the parts on duty they don't differ that much. Meaning that we can use an "average" size (and "local" topology) acting as the Jack for all trades.
3. Meaning that we can effectively solve the abstract topology with an abstract app the likes of GH and then place in properly defined coordinate systems all the real-life bits and nuts ... closely "emulating" a pro solution (that could "adjust" the parts as well).
4. This means that one particular C# needs more lines of code since as it is it defines cable axis on a per nod to node basis ... but in fact these are defined as the min segment between curves (circles to be exact).
5. Additionally the end part of each strut differs depending on how many pairs of stabilizing cables are used (either 2 or 1). Meaning some lines of code more for defining the proper coordinate systems for the instance definitions.

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

the bubble diagram. This algorithm works by a set of attractive and repulsive forces (as in Equation 9) acting recursively on graph vertices, seeks a ‘relax’ situation for a graph, and reaches to a graph drawing. This tool is quite intuitive and shows in real-time bubble diagrams neatly according to the specified areas and the connectivity graph.
Equation 9
Attraction: 〖AF〗_ij=ka ∆x_ij for all linked (i,j)
Repulsion: 〖RF〗_ij=kr /x_ij for all (i,j)
The attraction/repulsion strength inputs are denoted as ka and kr
in the above equations. If some configuration is very messy, you need to have a high repulsion first to untangle it. I have not tried Angel's method but it is very similar to the method we have scripted for this component.
I hope this helps.
Best regards,
Pirouz…
