    Question Pie Slices - a piece of cake

    The Challenge is to create a 800px circle (cake) with 19 equal segments (slices).

    Using Xara with no calculation and as simply and accurately as possible.

    Make a circle, clone it and transform it to a 19 point star, drag the inner points of the star to the middle, convert it to editable shape, break the inner nodes, group, combine/intersect shapes.

    OK. I know you said no calculations. And if that's the case you have your answer.

    I would divide 360 by 19 which is 18.64 degrees. Clone a vertical line and rotate from the bottom of the line 18.64 degrees to produce a 1/19 slice.

    Marco.
    Well done Marco.

    What I do is when I convert to Editable Shapes, I add a Line Width of 10mp and ensure the Star extends beyond the circle. Intersect All Shapes does the rest.

    Gary, thank you for presenting a more traditional approach.

    The way I do this is to clone a semi-circle and rotate the required angle and Intersect to give one pie slice.

    Your sum is a little wrong; it should be 18.947. Xara's input box will accept the 3 d.p.

    Your method would be necessary for polygons over 99 sides.

    P.S. Major broadband so fighting through. I apologise if replies are terse.
