no monsters in doom

Is there a way to play with no monsters. I would like to run around and enjoy to level design

Kill them.

I mean like the old doom where you could load a map with no monsters. Is there a way to do this in the console?

The only response.
EDIT: just download the map, take it into the editor and brush out the monsters.
