With the new version of MLCad, i hear about BFC, but, i'm sorry, i don't know what it is...

Could someone give me explanations ?

BFC means back face culling, it basically means that the rendering
program doesn't need to draw the faces that are not facing the viewer
(calculated by taking the dot product between a face normal and the
camera direction). It's there to make the rendering faster, you don't
need to worry about that if you're not creating a new part or writing a
CAD program. :)
What if I am creating a new part?
