I would say 95% of models I receive either as .RVT or .SKP wont go into Dialux as an .IFC for reasons that never seem very clear but indicate some kind of problem with the original model.
I cant believe the architects are building files that are of such low quality. But even if they are, they are not going to make major modifications to their filles or workflow to just allow the lighting design team to use the files in Dialux.
With the time constraints on projects trying to work in the BIM environment in Dialux is becoming unsustainable.
Is anyone else having better result?
