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 been created with Karamba 1.1.0 where all Loads are integrated into one component.
