Event: Karamba3D workshop, November 27-29 in Vienna: ) Course Fee: Professional EUR 825,- (+VAT), Student EUR 415,- (+VAT) Led by plug-in developer and structural engineer Clemens Preisinger, along with Zeynep Aksoz and Matthew Tam from the expert Karamba3D team, this three-day workshop will focus on methods of setting up structural systems in the parametric environment of Grasshopper. The participants will be guided through the basics of analyzing and interpreting structural models, to optimization processes, and how to integrate Karamba3D into C# scripts. This workshop is aimed towards beginner to intermediate users of Karamba3D. However, advanced users are also encouraged to apply. It is open to both professional and academic users. For beginner users of Rhino and Grasshopper, there will be an optional introductory course one day before the Karamba3D course. Karamba3D 1is a parametric structural engineering tool which provides accurate analysis of spatial trusses, frames, and shells. Karamba3D is fully embedded in the parametric design environment of Grasshopper, a plug-in for the 3D modeling tool Rhinoceros. This makes it easy to combine parameterized geometric models, finite element calculations, and optimization algorithms like Galapagos. Course Outline Introduction and presentation of project examples Optimization of cross sections of line-based and surface-based elements Geometric optimization Topological optimization Structural performance informed form finding Understanding analysis algorithms embedded in Karamba3D and visualizing results Complex workflow processes in Rhino, Grasshopper, and Karamba3D Places are limited to a maximum of 10 participants with limited educational places. A minimum of 4 participants is required for the workshop to take place. The workshop will be canceled if this quota is not filled by October 28. The workshop will be taught in English. Course Requirements Basic Rhino and Grasshopper knowledge is recommended. An introductory course is offered. No knowledge of Karamba3D is needed. Participants should bring their own laptops with Grasshopper and either Rhino 5 or Rhino 6 installed. You can download a 90-day trial version of Rhino. Karamba3D ½ year licenses for non-commercial use will be provided to all participants. Please register here……; Added by Matthew Tam at 6:38am on September 13, 2019

Comment on: Topic 'Refactoring Parametricism': ll geometry. The difference with programs like Inventor is that they are made for production, regardless of the fabrication method. I won't go into detail about that, and instead focus on the modeling process. In this little model, the starting point actually is a bit obvious, the foundation. The only contents in the 3dm file are 27 lines. These indicate the location of each footing, and the direction of the tilt of each column. Everything else is defined in GH with the use of numbers as input parameters. Needless to say, instead of those lines you could obviously generate lines and control the number of columns and panels, hence establish their layout, with any algorithmic or non-algorithmic criteria you please. That marks a major difference between GH and Inventor. You can generate geometry with Inventor via scripting/customization (beyond iLogic), with transient graphics for visual feedback similar to GH's red-default previews. However Inventor's modeling functions are not set to input and output data trees. I won't go into detail on that, but suffice to say that the data tree associativity of GH was for me the first major difference I noticed. I've used other apps with node diagram interfaces like digital fusion for non-linear video editing since the late 90's, so the canvas did not call my attention when I first started using GH. Anyways, here's a screen capture of the foundational lines: In the first group of components, the centerlines of the rear columns are modeled: And the locations in elevation for connection points are set. Those elevations were just numbers I copied from Excel, but you can obviously control that any way you please. I was just trying to model this quickly. The same was done for the rear columns: The above, believe it or not, took me the first 5 hours to get. Here's a screen capture of what the model and definition looked like after 4 hours, not much: If you're interested, next post I can get into the sketching part you mentioned, which is a bit cumbersome with GH, but not really. I wouldn't say that using GH to do this little model was cumbersome, it just needed some thinking at the beginning. You do similar initial thinking when working with a feature-based modeler.…; Added by Santiago Diaz at 12:44am on February 24, 2011

Comment on: Topic 'Trees missing': three categories, each one corresponding to different shapeType_ input:- polygons (shapeType_ = 0): anything consisted of closed polygons: buildings, grass areas, forests, lakes, etc - polylines (shapeType_ = 1): non closed polylines as: streets, roads, highways, rivers, canals, train tracks ...- points (shapeType_ = 2): any point features, like: Trees, building entrances, benches, junctions between roads... Store locations: restaurants, bars, pharmacies, post offices... So basically when you ran the "OSM shapes" component with the shapeType_ = 2, you will get a lot of points. If you would like to get only 3d trees, you run the "OSM 3D" component and it will create 3d trees from only those points which are in fact trees. You can also check which points are trees by looking at the exact location on openstreetmap.org. For example: Or use the "OSM Search" component which will identify all trees among the points, regardless of whether 3d trees can be created or not.However, when it comes to 3d trees there is a catch: Sometimes the geometry which Gismo streams from OpenStreetMap.org does not contain a "height" key. Or it does contain it but the value for that key is missing.OpenStreetMap is free editable map database, so anyone with internet access and free registered account on openstreetmap.org can add features (like trees) to the map database. However, regular people sometimes do not have height measuring devices which are needed for specific objects as trees.So "OSM 3D" component will generate 3d trees from only those tree points which contain a valid "height" key.However, a small workaround is to input a domain(range) into the randomHeightRange_ input of "OSM 3D" component (for example the following one: "5 to 10"): This will result in creation of other 3d trees which do not have defined height, by randomizing their height. randomHeightRange_ input can also be applied to 3d buildings, and it is definitively something I need to write a separate article on. In the end it may be that nobody mapped the trees in the area you are looking for. After you map a tree to openstreetmap.org then it will instantly be available to you or any other user of Gismo. I will be adding some tutorials in the future on how this can be done. But probably not in the next couple of weeks. Let me know if any of this helps, or if I completely misunderstood your issue.…; Added by djordje to Gismo at 3:52am on February 8, 2017

Topic: Cubic Close Packing: deform into rhombic dedocahedrons when they reach equilibrium. http://mathworld.wolfram.com/CubicClosePacking.html I was trying to model sphere lattice constrained within a boundary box. When inflated, they would not intersect with each other; they would stay in place; and would be malleable just enough to expand and fill in the gaps in between the spheres. I started off with the help of this thread here(Thanks for those contributed!). As I understood, there was a bug in Kangaroo2. Solver can't handle more than one item plugged in. So I tried to understand David's Stasiuk's Script and adopted it with a few variations, please see gh file attached. In the first 5 - I've used David Stasiuk's C# component-variable pressure (posted on June 9, 2015 at 12:25am): 'No. 4.5' being the most successful simulation so far(inflation value is kept very low so that they would not intersect); although I realised I made some math mistake in setting the close packing grid.(could be checked by plugging voronoi3D to see if the area of the rhombic faces are regular) No. 6-7 I tried with Kangaroo2 components. After consulting my tutor(Andrei Jipa)'s help, I realised the following changes could be made: - The definition posted by David on June 8, 2015 at 4:47pm with constant pressure would've worked better. - Icosahedrons with WbCatmull(Quad divisions) would result in more even load distribution. With wbloop, vertices more concentrated at poles. - Load in dir Z could be omitted. Andrei has suggested to use lengths(line) in Kangaroo 2 as 'pressure' instead. And I am trying to improve the grid; and maybe try with David's constant pressure definition. I will keep you guys posted of the progress! I am new to the parametric world, comments/advice very much appreciated! :) Zhini …; Added by Zhini Poh at 5:23pm on October 31, 2015

Topic: How to use properly LaDeform in load-controlled?: ing results and I think it is based on the assumption of small displacements. That’s why I want to try with LaDeform. But doing this I met some problems. I tried to experiment it on the small examples that are provided with Karamba: 1.LaDeform in load-controlled behavior I know Karamba has mainly been created make form-finding and not properly precise calculations, but I’d like to evaluate deformations of my structure under certain loads (load-controlled). It is said to let it in Default value for MaxDisp (-1). [Rhino view for deflection of the rope] In this example derived from a Karamba example (Large_Deformation_Rope.gh), the programs shows different ways to get approximately equal max deflection. But, getting into it, I realized Load Multiplier for gravity is different from one model to another (-3.237 for Analyze TH1 and -134 for LaDeform). So what is the interest of the example if the quite similar shape of deflections are not got under the same loadings? (quite different loadings indeed) Doesn’t it show on the contrary that LaDeform algorithm does not work properly, if you need to change the load multiplier? The Grasshopper file is shown below. 2.MaxDisp When I use the model is “max disp”, I command the deformation, but how can I get the value of the virtual force exerted (which I don’t know because it is now imposed)? What is its link with the imposed deflection? Otherwise I can’t figure how to use it with displacement-controlled loading 3.Iterative process As it seems impossible to use LaDeform process, I tried to test it by iterations, as you recommend it on the forum, saying that it is equivalent to an iterative Analyze Th1 process. I tried to reproduce this loading but the result is not very enthusiastic as you can see. The Rhino file shows the progressive loading, with the corresponding Grasshopper files, where I - disassemble the model, - get the previous deformed model - put in another part of the load, - re-assemble and then calculate it on the previous deformed shape. Do you have any idea why the answer is not the same ? (LaDeform seem to give like 5 times less for the same loadings) (and even controlling it by displacements the shapes do not fit the principle of the algorithm would let think) [RhinView for Iterative process] First step by analyze Th1, and result by LaDeform 4.Analyze Th1 after LaDeform? Some tutorials of Karamba show that an analysis with Analyze Th1 is sometimes made immediately after a calculation in large deformations. What is its reason? It seems to sometimes change considerably the result. What is the sense of such an operation? Would it mean that LaDeform is not trustworthy? ð My question is then: is there a way to make the use of LaDeform for other purposes than form-finding affordable and coherent? If I mistake using it, where? Thank you very much for your help, …; Added by Fourdi at 12:53am on May 18, 2016
