cided to expose the real-thing (something that is under construction these days, a "bit" bigger than the "demo" examples provided up to this point - around 25K m2). This means a more complex definition (a "bit"). The real thing is not made with GH.
4. Membranes are treated with 2 ways: Kangaroo (bad news: you receive a mesh that is anathema for shop-drawing level studies). MinSurf + trim (nurbs on hand but with the obvious disadvantages as regards "relaxing" the other components - more code, less time for windsurfing)
5. Puzzle: do you know that big "umbrella" thing made recently in Saudi Arabia? (colossally big membranes that ...er... hmm..."fold" - 1M times the size of an umbrella). Never heard about that? Shame I must say, he he.

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.
Thanks,

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? …

and Grasshopper. Recently I tried doing some test project just to see what can I do. My target is to design a small house for an atom family. Though as you might think - it'll be a parametric one. And I encountered exactly what's in the title. So here it goes: 1. Something is wrong with the measuring units in the complex profiles. I met this problem while making I-beam. In ArchiCAD it had 127/76 mm while in Grasshopper i had 127000/76200mm so a little bigger. 2. I'm unable to turn off the preview. I mean when I delete something in Grasshopper/Rhino it still exists in ArchiCAD. I have to unlock it and then delete it. 3. Coordinates for points seem broken. They have to be multiplied 1000 times to match. 4. Now one of the most important. Is it possible to somehow SHOW Grasshopper where are already made in ArchiCAD objects. Even if they'll remain still. For example I want to make a parametrical roof. Do I have to model whole building from scratch in Grasshopper or is there some fast way to "import" existing scene so I can limit my work with Grasshopper only to parametrical one. 5. Is it possible to make "points" as controlling points in AC? Like, if I'd like to make a beam in a desired place which I will mark by that point and then I will "show" Grasshopper that point and tell it to make an object in there so I can control it within grasshopper. I tried ti do this using AC Control Point but when I click "Send changes" button, Grasshopper and Rhino crush immediately. It only happens then, with control points. 6. It seems that "move" component won't work with "2D curve" component connected directly. It is possible that some of those problems are outdated. I was playing around in Grasshopper a few months ago, before summer break, but now I plan to try something new and it would be nice to know what to do. I appreciate any answer to any of those questions. Please help, you guys, are my only hope. Thanks in advance! Karol…

I dont get any error messages in either LB or HB. HB says it has all libraries in its text output.I'm using a vanilla install of Win 10 with standard win firewall unaltered. I have a feeling it has something to do with files not downloading all the same.c:/Ladybug does not exist.
Picture shows contents of roaming/ladybug folder. is something missing?
This is what i've done so far:
Followed all the steps on the install instructions.Uninstalled and installed it again running in administrator mode.
Tried to get files from this thread, but links are broken to download those outdated files. I think I remember I usually have to do this when i do HB installs on new OS...I have not installed open studio, only energy+…
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…
