    Help needed: How to draw a cone ??

    I have forgotten all of the mathematics I once knew !!! Can some kind person give me the formula for drawing a cone that can be cut out. i.e. the trim indicator on the A320 is sloped at 45 degress and is part of a cone, and I am hanged if I can figure out how to put it into Coreldraw so that I can cut it out.

    Regards all.....................Brian W.

    Math? Whats that?

    Don't quote me on this as I'm most likely wrong....

    Draw a circle and remove 2x the angle you want to create.
    For 45 deg, remove 90 deg of the circle and then roll the cut sides together.
    Use paper to test and when you get it right, let us know what the correct angle was.

    Glad it worked for you. I was not sure if I remembered it correctly.
