Relux Desktop has had an import and export interface for rooms on an ASCII / text basis for some time.
This has been fundamentally revised and extended to the entire project.
Now you can transfer several rooms with objects (windows, doors, extrusion bodies, etc.) and luminaires (as Eulumdat, IES or ROLF) to Relux Desktop in one XML.
After planning and calculation, the results can be exported back into the same XML format.
This interface is interesting for connecting CAD and other applications (Excel, Python, databases, etc.) directly and bidirectionally with Relux. Planning processes thus become much faster with fewer transfer errors. The XLM structure (XSD) is freely available and can be used by anyone free of charge.
