    When you have a sphere (Meaning a circle in both the plan and elevation), do you divide both circles into 12 parts and join up the corresponding points from both views? Because I've done that and it's not working out in the centre projection at all.

    Do me a favour please....

    Get a ball (or any other sphere). Set it on the table. Look at it at eye level... you see a circle. Look at it from the top... you see a circle. Look at it for the side... you see a circle. Look at it at an angle... you see a circle !!!!!

    A sphere always appears as a circle. So just project the two center points and lob the compass on the center point and bang ! Job done.

    Wow. I would never have thought of that. LOL. Thank you so much. My DCG teacher sucks, he barely explains anything, even though he claims to have helped design the new Wembley.
