    Hi sketchupers,

    I have a problem I cant work out the solution to:

    I want DC to draw a segment of a circle including n degrees.

    i.e. I want to be able to divide a circle into any number of (pie slice shaped) sections based on a variable.

    any ideas?

    A bit more detail:

    I created a dynamic component for drawing out a tower form based on the motion of a mechanical iris, it's here: (or in the 3d warehouse)

    I wanted to make a new improved version, which had as a parameter the number of segments the tower was divided into. I realise I can do this with triangles again by scaling the triangle differently in two directions to alter its shape and so the angle at its vertex. However, what I would really like to do is base it on segments of a circle ( so that the outer edge of the tower is more obviously different from the other edges ) so the scaling technique will not work as it will distort the curve.

    I could of course remake the original (with a fixed number of segments) with a curved edge, or build different versions for each number of divisions, but both of these seems like a cop out, so any ideas?
