Imported models disappear

Los archivos importados tanto los interiores como los exteriores desaparecieron de mi modelo de D5. Lo guarde en un archivo drive y cuando quise volver a abrir ocurrio ese problema.

The imported files, both interior and exterior, disappeared from my D5 model. I saved it in a drive file and when I wanted to open it again that problem occurred.

@solalanizp It is recommended to save your D5 files locally for optimal performance. Are the imported models also saved on a cloud drive? Additionally, I would like to know if the files were imported directly or synchronized with a plugin. Please save these files locally check if the models become visible in D5. Thank you.

The imported models are saved locally and were synchronized with a plugin with revit. But also d5 assets are gone.
