At the moment Dialux EVO accepts only .3ds, M3D, SAT or IFC 3D formats. Which is very ok, but it should be very useful that importing the number of 3D formats will be extended to e.g. .STP/STEP, .STL and DAE (Collada) (.OBJ/FBX/GLTF/GLB are already mentioned/asked for by another community member) .
