Clearing large areas

[Bigpappa305]

Is there a machine that can clear a large area to bring it down to one specific level? I know the Terraformer can make things level but I haven't used it before, can you stop it? does it affect user placed blocks?

How large is large?

I just use a Destruction Cat on max power. Doesn't take long.
