It sounds like you need to do some model management in Revit--a 600 MB file is fairly large.

More important however is how many polygons / triangulated surfaces the model contains, which is most likely what is driving up the file size in the Collada export.

Try breaking up the model into Worksets--turn off un-needed elements that you don't need in the Lumion scene.

Purge the Revit model.

Delete any Raster Images

Delete any Cad Links or Imports

Take a look at Families which are loaded into the model. Check for any alrge file sizes ( .rfa)

If families are large/complex/have Cad imports contained in them, this will bloat the Revit file and subsequent exported Collada file.

Try using a Section Box to cull/crop the view that you export for Lumion.

Are you using the Lumion plug-in to export? There may be settings there as well- not sure about that.

Hi @A.Sobhy

You can minimize the size of your Revit® files in order to optimize project performance.

Remove unwanted cad/rvt links and unused raster images in your model.
