Hello @sandeep.parashar,

As part of the [quickstart](https://docs.techsoft3d.com/communicator/latest/overview/quickstart.html#quickstart) module, there is an example of creating an overlay in the viewer. You can then add a [circle](https://docs.techsoft3d.com/communicator/latest/api_ref/viewing/index.html#generatePointsOnCircle) inside the overlay object.

To view the overlay example, please do the following:

1. Launch the server application by double-clicking _start\_server.bat_ in the directory _HOOPS\_Communicator\_202X.X.X\quick\_start_
2. View the overlay example by clicking this URL:

Thanks,  
Tino
