What sets ReluxCAD for Revit apart?

Clear display of complex products

Interior & exterior measurement areas

Simulation of passive infrared sensors

Massive time savings and productivity

Bidirectional  interface with ReluxDesktop

Reach your goal in three simple steps


1. Select luminaires and sensors

The add-on imports rfa, ies, ROLFz and GLDF files and automatically adapts them to the particular Revit version. Select your luminaires from the vast ReluxNet search database and use also Eulumdat. 

Using neutral products in your planning? Import them and include the light distribution curve.


2. Assign and calculate

Inform the Room Manager of the main activities carried out in the rooms, then obtain the requirements with regard to standards. 
Select the desired luminaire type for the basic lighting.

The build-in radiosity lighting calculation places the luminaires automatically into each room and provide full photometric results.


3.  Display results + luminaire list

A usage list is created to clarify which luminaires are to be installed where.
The lighting simulation can be displayed in 2D or 3D.
