SU²CATT

SketchUp to CATT-A Exporter

made with SketchUp

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).

If you've made your acoustic models within CATT before, this will save you tons of time. We actually developed the interface for in-house use first, and later decided that other people might benefit from it too.

"The use of SketchUp allows the user to create a building model for simulation VERY quickly and intuitively. It allows the software people to focus on the thing they are good at (Energy / Daylight / Acoustic modelling ) rather than on visualisation and geometrical modelling. It brings closer my personal Nirvana: Skecth design using full simulation tools, rather than cut-down 'simplifications'. What is most important to me, after many years of working with various geometry exporters based on the autodesk 3ds or dxf formats, is that in the experiments I have done with Daysim and CATT, the models exported from SketchUp are much less complex. Fewer polygons. Less calculation time. Less need for this type of geometry simplification."
