Hi Guen,
We’re not seeing issues with Arkio’s Revit plugin to load files from Arkio back to Revit 2025 but large scenes with lots of imported geometry can sometimes fail to convert. The educational versions of Revit and Arkio are the same as the paid versions so there should be no difference there.
Did you use the Revit plugin to download the exported files via the Arkio cloud first and then import the files locally or did you export your scene from Arkio on PC? And do you get any warnings when importing the file? Can you share the files that are giving you import issues with us at support@arkio.is? We can then look into this and see what might be going on.
