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. |
