For example, single finger dragging model, double finger translation model.

Hi!

Communicator’s operator functionality supports [touch events](https://docs.techsoft3d.com/communicator/latest/prog_guide/viewing/operators/operators.html#overview). You can also inspect the [operator source code](https://docs.techsoft3d.com/communicator/latest/prog_guide/viewing/operators/operators.html#built-in-operators) for operators that utilize touch events (such as CameraNavigationOperator.ts) that is provided in the Communicator package at web\_viewer/typescript/operators.

Thanks,beau.  
For example, can I set up a single finger drag model or a double finger drag model? If possible, how should the code be written?

You’re welcome! Yes, that is possible. I recommend taking a look at the source operator code for samples of how the pan operator is implemented for dragging the model. Here’s a very minimal example of handling touch events: [https://3dsandbox.techsoft3d.com/?snippet=0n9FmMGCf9ENmH51ohoLUu](https://3dsandbox.techsoft3d.com/?snippet=0n9FmMGCf9ENmH51ohoLUu)  
If this is unclear or if I’ve misunderstood your question, please let me know!
