Hello everyone,

I have created a lighting design for a building using a 3D model built from PDF drawings. Since working with the architect's IFC model is not possible due to its large file size, I created the base model and intend to export only the luminaires as an IFC model and place them in the architect's IFC model, as it contains the correct heights. However, the luminaires are changing from IES files to object files, and exporting to AutoCAD is also not working. Additionally, I cannot load two IFC models in DIALux simultaneously. This means I cannot load the IFC file I created with luminaires in DIALux while another IFC file is already loaded. Does anyone have any thoughts or solutions for this?

Thank you in advance for your help!
