A Problem Wtih Boolean

Hello,
I have a serious problem again.
When I add a Boolean Modifier to my Mesh
this happens.

The Problem is: where are all the vertices
and edges which must be there. Instead there
are big unreal Faces.This happens in all
Boolean operations i do. How can I display all
the existing vertices and edges.
I’m concerned about this issue especially
because of the export of the model and than the
G-Code generation.

How can I display all
the existing vertices and edges.
There are non, it is a single face that happens to have more then 4 edges. You can triangulate the face if you need to (Ctrl+F for face specials menu)

Thanks Richard Marklew
