Karamba3D

ADDON. Version 2.2.0.180. Released on 16-Jun-2023. Provides 98 components. Created by Clemens Preisinger. Features 4 video tutorials.

Karamba3D is 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. It lets you analyze the response of 3-dimensional beam and shell structures under arbitrary loads.
