Good day everyone.

I am an Architect who primarily works in Archicad, Revit and SketchUp. I recently started to learn my way around Blender as I would like to use it as an Architectural visualization tool.

I can export a building from Archicad just fine, import it into blender, apply materials, lights etc. just fine and render it.

The problem I'm running into is that whenever I have to make changes to the Archicad model I don't know how to go about re-importing the updated CAD file to blender without having to redo everything in blender ( materials, lights etc.)

Is there a way to do this in Blender similarly to programs like Lumion and Artlantis?
