Plan your lighting installation directly in AutoCAD

ReluxCAD for AutoCAD provides planners and engineers with a powerful tool that simplifies and optimises lighting planning by enabling precise calculations, realistic visualisations and efficient integration into existing CAD workflows.

ReluxCAD offers extensive lighting calculation functions directly in AutoCAD, allowing planners and engineers to perform accurate and standard-compliant lighting calculations without having to leave the AutoCAD environment.

Using the built-in interface, you can transfer 3D objects from one application to another via copy & paste. A great performance for a low financial outlay!
