This problem is really doing my head in. The instructions I've been given want me to put an M5 tapped hole through the top of this cylinder (where the plane is showing) using the hole wizard. It has to go right through the wall to underside. It then has to have a M5 socket screw going through that (which I can't seem to find). I'm just starting out and the manual I've been given is pretty crappy. Any help greatly appreciated!
