For all acoustical simulations you will need to import a geometry into ODEON. The geometry can be modeled in many different 3D programs. Normally we recommend using SketchUp, since it is the easiest to work with together with ODEON, but a range of other software work as well.
Guidelines for making 3D room models
3D room geometries are typically not made within ODEON, but rather, the user imports models created in an external CAD software.
However, 3D models for acoustic simulations in ODEON need to be made with different considerations than 3D models for architectural visualisation.
This video explains the most important guidelines to follow when creating your own rooms to import into ODEON.

Importing geometries from SketchUp
ODEON’s free plug-in, SU2ODEON, not only allows to export Sketchup models into ODEON, but even use both programs simultaneously and easily update changes! This makes it easier than ever to change the geometry while working with the acoustic simulations in ODEON.

How to combine or add geometries
There may be times when you need to add new geometry to your 3D model after having spent time setting up the ODEON model. The video below shows how to combine geometries, or add surfaces to your current model, when you are importing your geometry from a CAD software other than SketchUp.

IFC BIM, to SketchUp, to ODEON
By combining SketchUp with the IFC plug-in and the SU2Odeon plug-in, it is possible to take building information models, import them into SketchUp, remove small unnecessary details, and then import it into ODEON. The different elements in the model will be grouped in layers, allowing you to easily assign materials to all elements of the same type, i.e.: concrete to all walls, or wood to all doors.
