You can export your 3-D DesignBuilder models for further daylighting, visualisation and other analysis using the free version of Google SketchUp as an intermediate step.
All of the models on this page were created in DesignBuilder, exported in 3-D DXF format using the 'Whole model with details' option and imported into Google SketchUp where details such as textures, trees, people and shading were added.
