I was reading this http://wiki.blender.org/index.php/Doc:2.6/Manual/Modifiers/Generate/Booleans
It states that my modifier must be added in object mode, with a face to work.
I created a circle added a face. Named it Circle I have a plane named it beam. I added the modifier to my circle to cut a circle out of my target beam. I am not getting a result. What am I not doing?
