The team at the University of Virginia has created a series of Karamba3D examples to guide users through several workflow processes. Each example is thoroughly explained and the geometry is internalized to run without supporting Rhino files. Input new rhino geometry into the Grasshopper definitions to see how the geometry performs. Difficulty: Hard This definition […]
Difficulty: HardA set of lines are projected onto a surface. The cross section optimizer determines the appropriate cross section sizes for each element. By setting eccentricities for the beam elements, the beams are aligned with the original surface. Get the grasshopper definition here: 05_Projectedarrayoflines.ghThis example uses Karamba3D 1.3.3.
Difficulty: Hard (PRO version only)A Voronoi pattern is projected onto a surface. The cross section optimizer is used to specify the thickness of each member. By using the Beam Orient component, each element can be orientated individually to align with the input surface. Get the grasshopper definition here: 05_ProjectedVoronoiPatternGridshell.gh This example uses Karamba 1.3.3.
In a four part tutorial, Junghwo Park explains how to export a gable truss structure created in Revit, into Karamba and finally back into Revit again. These two tutorials (part 2 and 3) explain the process of importing the .dwg file (created in the Tutorial 1 – Export a Gable Truss Structure from Revit) […]
Difficulty: HardShows how to scale the size of openings on a surface depending on internal forces. Make sure to open the Rhino File which has the reference geometry. Reduce the surface U & V Count to 2 for viewing in the TRIAL version Get the grasshopper definition here: 05_InformedGeometryScaleOpeningsByInnerForces.gh Get the reference rhino file here: 05_InformedGeometry.3dmThis […]
Difficulty: Hard (FREE/PRO versions only)The properties of modules are made dependent on the internal forces of the structure which is a tetrahedral space grid. Make sure to open the Rhino File which has the reference geometry. Get the grasshopper definition here: 05_InformedGeometryScaleModuleEdgesByInnerForces.ghGet the reference rhino file here: 05_InformedGeometry.3dmThis example uses Karamba3D 1.3.3.
In a four part tutorial Danil Nagy explores structural analysis and model assembly in Karamba. A twisted tower is set up parametrically in Grasshopper and then the geometry can be input into Karamba for structural analysis. The tutorial uses Karamba 1.0.5 where Point Loads, Gravity, etc are separated into different components. The source definition has […]
Difficulty: ModerateCross section forces of a structure under dead weight are used to scale the cross section heights in a rectangular grid of beams. Contains a trick regarding the flexible definition of support positions. Set the Grid to 3 x 2 for the to view with the TRIAL version. Get the grasshopper definition here: 05_CrossSectionHeightsFromMoments.gh […]
