Rhino2CATT allows acousticians, architects, and designers to prepare complete CATT-Acoustic models directly within Rhino.
Users can model geometry, assign custom acoustic materials with frequency-dependent absorption and scattering coefficients, and define sources and receivers. With its dockable panel, Rhino2CATT integrates seamlessly into the Rhino environment, streamlining model modifications and optimization, making them faster, easier, and fully integrated with Rhino and Grasshopper workflows. Built on algorithms trusted by world-renowned acousticians, Rhino2CATT ensures efficient and accurate model setup.
Key features include automatic geometry export with vertex optimization, custom material libraries, and custom directivity and spectra databases for sound sources. Export your model to CATT-ready files (.geo,.loc) with a single click for a highly efficient Rhino-to-CATT workflow. BIM-based workflows are also supported via Rhino.Inside.Revit, ensuring smooth collaboration between architectural and acoustic modeling processes.
