Like this: a boolean Diff of a volume by a segment(s) drawn on a face(s)! ;)

Don't forget to kill or Hide the segment(s) before other actions!

If you want keep some volumes use the Boolean Merge...



Here with 2 segments on 2 different faces and Explodemove move after the Boolean Merge or Diff
(Press Tab and write ExplodeMove (with any capital letters but without space ) EXplodeMOve will work E xplodeMove not!
You can also make a shortcut
ExplodeMove (or explodemove... etc)
