What is SU²CATT?

SU²CATT is a SketchUp extension to export SketchUp models to CATT-Acoustic files. It exports models generated within Sketchup to the native .geo-format of CATT-Acoustic, including export of layers into several .geo-files and separate file with absorption material definition (ABS-directive in CATT). We actually developed the interface for in-house use first, and later decided that other people might benefit from it too.
