Hi

I Can't print a hole in cylinder. And I really don't understand why.
Take a look on this pictures please. And this what i got if I am trying to print What I am doing wrong?

Take a look at the bottom right on the advanced tab and remove the check mark if there for the merge all outlines into a solid model.
It says something like that.
