Supported 3D file formats

In general, TownScope is used for calculation purposes, so it does not need to import any texture or beautification effects into the 3D model.
Important : In some solid modelers the Y and Z axes are reversed. In TownScope the Y axis of the 3D scene coordinates is assumed bottom-up in the screen plan.
For example, if you are using Google Sketchup you must check the 'Swap YZ coordinates (Y is up)' option in the Export/options dialog pane.
Very important : the north direction is crucial for solar access calculations. TownScope considers this direction to be bottom-up on the screen when a scene is displayed in plan projection. You can change the orientation of your model in the CAD tool or through the transformation window.
Hereafter the list of all the supported formats along with the limitations on each one.
