Rhino2CATT
Create complete CATT‑Acoustic models — directly inside Rhino.
Model geometry, assign materials, define sources and receivers, and export with a single click. Seamlessly integrates with parametric workflows, allowing rapid iteration of Grasshopper designs and instant acoustic assessment. Save time on model preparation, enable faster design iterations, and streamline your CATT-Acoustic model setup.
Features
Geometry Export — Export Rhino surfaces directly to CATT-Acoustic .GEO files with automatic plane detection and vertex optimization.
Material Assignment — Assign acoustic materials with absorption and scattering coefficients to individual objects or entire layers.
Source & Receiver Definition — Create natural or electro-acoustic sound sources with customizable properties including orientation, sound power level (SWL), and directivity patterns. Define receiver positions with visual feedback and automatic naming.
Custom Material Database — Load and manage your own material libraries with frequency-dependent absorption and scattering data.
Directivity & Spectra Databases — Import custom directivity patterns and source spectra for accurate electro-acoustic source modeling.
One-Click Export — Complete Rhino-to-CATT pipeline in a single click — geometry, materials, sources, and receivers exported together for rapid acoustic assessment.
Autodesk Revit — Supports BIM-based workflows via Rhino.Inside.Revit.
