There are two problems: first, after cutting and selecting, still selected is the model that is cut, I think this should not.2: how can you let the camera go underground and operate normally?

Hi there,

Can you give us a bit more context, maybe a code example using Sandcastle?

For #2, we do not current support camera controls for underground, see #5665.

Thanks,
