While developing DIALux evo it is important for us to provide the user with an easy-to-use interface. In DIALux evo you are guided step by step through the process of lighting design. You start with a floor or ground plan and crate the basic geometry with a few simple clicks. Then you select suitable luminaires from the DIALux plugins. Here you will find over 1990 different luminaire catalogues from leading manufacturers. After you have placed luminaires and furniture in your plan, you start with the light calculation. You can export t as a pdf. document or as a drawing to your customer/client.
