making a hole?

Greeting all,
I just got hold of fsds2 and have begun building. My question is - aftyer creating a basic fuse out of a tube, how do I make the hole where the cockpit will be?, I cant just delete points that already exist as there are no points in the right place.
Forgive me if I am being blatently dull I am new to this stuff
