Can the annotated model, be saved?

[dhruv.jain9100]

I have a use case where users can annotate the model freely using a pen tool, which is already available in the Hoops Communicator web viewer. However, I want to store the updated model along with the annotations so that when users return to the viewer, they can resume from where they left off, with their previous annotations intact.

Are there any specific methods, resources, or documentation that could help with this?

Hello @dhruv.jain9100,

Yes, it’s possible to serialize markups via the MarkupManager class. Of note are two functions below:

• exportMarkup()
• loadMarkupData()

More information is also available in our docs.

Further, as part of the quickstart module, there is an example available in the Communicator package. To view this example, please do the following:

• launch the server application by double-clicking start_server.bat found in the directory HOOPS_Communicator_2025.X.x\quick_start
• load the example in the Web Viewer by clicking this URL:
  http://localhost:11180/markup_export.html?viewer=csr

Thanks,
Tino
