[feature request] Carving out a cave/mine

A system for carving out a cave / mine would be great.

Can’t you do this in landscape using sculpt with Remove instead of Add selected?

As far as I can see, the remove tool removes an entire block of terrain, instead of “etching” some of it away. Can you tell me the exact steps to make that feature to work, if it exists at all?

Ok, thanks for clearing that up.
