​

✅  2D to 3D – digitise plans easily → Free of charge

✅  AI image generation → 5 free credits​

✅  Integration of EN1838:2024

✅  Interactive Mode in real time

✅  Further new features

With the new 2D-to-3D conversion feature in ReluxDesktop, floor plans from PDF files can be automatically recognised and converted into 3D spatial data.

An AI has been trained with many floor plans and rooms. It recognises rooms, windows and doors from PDF files. It does not matter whether the PDF file contains vector data or pixel images. Photos and sketches in a PDF file can also be imported. The tool is provided free of charge.

Entire storeys are interpreted with their rooms. The tool makes it possible to scale, rotate and select a section from the content of a PDF file. The rooms are then manually supplemented with names and usage profiles in accordance with current standards.

With the free 2D-to-3D conversion, rooms only rarely need to be traced manually. This saves a great deal of time, especially with many rooms and storeys. A check and, if necessary, a correction remain necessary. The reliability of the AI is high and continues to improve.

✅ Create 3D data from floor plans with AI

✅ Recognise rooms, windows and doors

✅ Storey editor: scale, rotate and geometrically correct rooms, and add usage profiles

RELUX offers an AI-supported service for the automated recognition of rooms, doors, windows and storeys from uploaded 2D plans. Processing takes place on RELUX servers. Corrections made by users may be used to improve recognition quality and to further develop the AI models. Only the data required for this training purpose is processed.

Personal data is avoided wherever possible, or processed in anonymised or pseudonymised form. Processing is carried out exclusively to provide the service and to improve the recognition algorithms. Users can object by not using the free service and continuing to work manually as before.

Create realistic visualisations of your lighting design with one click. The AI generates high-quality interior scenes from a RELUX lighting calculation. It automatically takes into account room geometry, materials, colours, windows, doors, lighting-related properties, as well as the number and position of the luminaires used. The RELUX lighting calculation, the room name and the usage profile are also included.

The images are available in the output and are saved with the project file. The AI image service is subject to a fee and is billed via user-specific credits. The current focus is on interior scenes. Custom user prompts are not yet supported.

✅ Realistic visualisations with little effort

✅ Enhance presentations

✅ Visualise different room scenarios

RELUX offers the option of creating AI-generated visualisations from RELUX calculation results. For this purpose, a technical RELUX service is used to access Google’s “Nano Banana” image generation service.

RELUX does not transmit personal information such as names, email addresses or customer data to the image generation service, unless this information is entered by the user in prompts or included in the content to be processed. Users are advised not to enter any personal or confidential information in prompts.

The generated AI images are intended to visualise the lighting situation. They do not correspond to lux specifications. The transmitted data is processed exclusively to carry out the requested image generation. The data transmitted to the image generation service is not used to train general AI models. Further information on data processing by the service provider used can be found in Google's privacy policy.

Emergency lighting is a key topic in lighting design – with direct effects on the safety of building users and compliance with legal requirements. The EN 1838:2024 standard is fully included in the 2026.2 update and changes the assessment approach: 

Minimum illuminance of 1 lux across the entire usable escape route area.

✅ With the updated automatic placement, the spacing is now calculated based on the area-based approach of the new standard.

✅ The integrated planning aid tool calculates geometrically and very quickly which luminaire spacings are required to achieve 1 lux across the entire defined area.

✅ Live results across the entire area: the real-time illuminance display shows directly whether the entire escape route area is correctly illuminated – including the edge zones.

Interactive Mode enables dynamic and fluid real-time work directly in the 3D view of ReluxDesktop. Instead of starting a manual recalculation after every change, the program updates the light distribution and results immediately in the background when luminaires or objects are edited. This real-time feedback makes it much easier to experimentally adjust positions and angles throughout the entire planning process.

✅ Immediate results view: every movement or rotation of a luminaire is shown directly in an updated visual representation​​.

✅ More efficient alignment: complex lighting concepts and precise accent lighting can be optimised without time-consuming calculation pauses​.

✅ Smooth workflow: the constant switching between construction mode and separate calculation runs is no longer required​.

The “Interactive Mode” function is activated in the “Sport” navigation.
