New in DIALux evo 14: Same objects? One click is all it takes.
With DIALux evo 14, working with objects that appear multiple times in your project is now much easier. You probably know the situation: a certain chair, door, window or luminaire has been placed several times in your project, and you don’t want to search for and click every single object manually. That’s exactly what the new “Select all of this type” function is for.
Coming Soon: Merge Multiple IFC Models Directly in DIALux evo
In BIM workflows, a project often consists of more than just a single model. In addition to the building model, there are usually discipline-specific models, for example for HVAC, plumbing, or electrical planning. Until now, these models had to be merged using external software before being imported into DIALux evo. We are currently working on a new feature that will allow you to import multiple IFC files directly into DIALux evo and merge them into a single, unified model.

Lighting design is a global profession and learning the right tools should be just as accessible. That’s why, beyond our courses held hybrid and on-site, we have built a worldwide network of certified DIALux trainers who support users locally, in their own language, and directly on site.
