I’m currently working with the WebViewer and trying to figure out if it’s possible to save the updated model directly from the viewer and then reload it later with the changes applied.  
From my research, it seems like we might need to create a separate PRC file to store these updates. Could anyone provide more details and if any better options available?

Hello @praful.bharate,

Saving modifications **directly** in the Stream Cache file cannot be done. Changes would have to be re-applied when the model is reloaded in the Web Viewer. To help with data serialization, certain classes in the Web Viewer API have a `toJson()` function.

Thanks,
