3Dsolar is a multiplatform building modelling software by ALware, especially designed to create the input data for lighting simulations. This program enables you to create a parametric building model very quickly in the design phase, so that the impact of lighting can be optimized before any final design commitments are being made. The models are strictly hierarchical, so that changes on any level will propagate immediately through the complete building.
3Dsolar is perfect as an input tool for Rayfront, which will then help you to configure all the details of your lighting simulation.
3Dsolar is used for consulting work by ALware. They also offer it for rent to interested customers.
