Camera Limits and Annotations are incompatible in the regular viewer and 3D Settings. However, it is possible to combine the two features when using the Viewer API to build an application on top of the Sketchfab viewer in your own website.
There are three options to do this:
- Create annotations in 3D Settings like usual, and then use the Viewer API to enable and disable camera limits as needed.
- Enable camera limits in 3D Settings like usual, and then use the Viewer API to create annotations at run time.
- Use the Viewer API to manage both camera limits and creating annotations.
Check out this example. Notice how the "front" and "back" of the product have their own camera limits and annotations.
