DRAWING CIRCLES AND LINES
Hi there, wondered if anyone could please help point me in the right direction.
I want to draw two circles of different diametres (poss 120mm & 100mm approx). On both of these circles I want to draw straight lines radiating
from the centre out to the edge and evenly spaced resulting in a circle with 26 equal sized segments.
Does anyone know of anything on the NET or some free software that'll do this. Would prefer something that would do it automatically and
geometrically correct when told specific dimensions and or angles.
I suppose it doesn't really have to be a circle either - it could be a 26 sidedahedron (or whatever it would be called), but would prefer a
circle.
Bit of a strange question I know, but would appreciate any input if anyone knows of anything idiot proof 
Cheers

does it have to be on comp, or could you do it on paper, just draw a 100mm line with a ruler, then get a pair of compasses and mark at 50mm then draw
your circle. circumference is pie time diameter which would be 314...... then divide that by 26. which would be 12.1 ish, set your compasses to 12.1
and mark from the end of your line all the way around the circumference, then connect up all the places where your marks cut the circle, easy!

Hi thanks for that, but really wanted it on the PC as was probably going to print one onto clear OHP sheet.
Cheers

No problem. I've sent an email, let me know if it doesn't arrive.
I have sent a JPEG and a PDF.
The PDF should print out at 120mm and 100mm diameter at A4.
(You might want to check there are 26 segments! It's been a long day, and I keep losing track on the screen!).
Cheers
Mike
