Hi everyone,

I would need help to find a simple software that I could print a circle of up to 6 inches (15cm) in diameter on white paper. It needs to be pie shape in black for my optical reflector switch off times. It's very simple, if my motor rotor has 8 poles (on times) then the circle would have 8 black pie and 8 white pies equally spaced in the circle. That's all I need but I can't seem to find anything.

So please help my out if you know of something or have some time to look.

Thank you for your help

Thanks, I'll have a look but if it's not obvious how to do it within the first minute I'll pass on it.
