Ibis is a library of Geometry Analysis tools for fabrication processes. Problem definition: We model all these generic geometries and do not consider materiality unless we are rendering visualizations or doing FEA analysis. The plugin incorporates Fabrication techniques, constraints + material properties at early design stages and allows for optimizations and fabrication-related problem solving by plugin into Grasshopper’s parametric engine modeler. This feedback loop between fabricators and designers brings fabrication considerations forward to inform design decisions as alternatives are being evaluated. Such file-to-factory workflows are becoming increasingly important as designers aim to keep up with new technologies, materials and fabrication tools.
