    This is the way I would do it, it's also very quick.

    As a matter of interest only:

    Although Fred's method creates a 'circle' it is not an exact circle. The shape is very circular but not a true circle. But then again neither is a circle created by the ellipse tool. To test this out zoom to 10%, create the largest circle you can which is still totally visible. I created on one 7000 x 7000 px. Now rotate it 22.5 degrees, it becomes 6997.9 x 6997.9, two pixels smaller, how can this be, shock, horror

    Can anyone confirm my video is streaming. I can see it but several hours later Acorn cannot.

    Yes, video works fine here Egg.

    Note: Fred & I's method works fine here and produces a 100% perfect circle.
    But remember to use 'Radius' or 'Diameter' creation. NOT bounds.

    This is the point I noted out of pure interest Steve, it doesn't create a perfect circle. Create a circle with the ellipse tool. size it to 300x300px. Create the circle via your quick shape tool method. set it to 300 x 300px. Select both and align together centrally. Zoom into top left side in wireframe, there is a gap. Not at the top, bottom, left or right sides but at the intermeadiate points nw, ne, se & sw.

    So it creates a circle that for all intended use is a near enough circle, but not the perfect circle

    Yes, the more sides you use the less the bezier error is noticible. Do it with less, a square and notice the results.

    Interestingly enough, Bezier curves can approximate a circle but not perfectly fit a circle.
    FROM http://stackoverflow.com/questions/1...%A9zier-curves

    The only real world application I see this mattering in, but not a great deal is if you have contraint set to 45 degrees, holding down Ctrl, draw a line horizontal, at 45 degree restraint and then vertical. Change the 45 degree line to a curve with smooth join. This doesn't give a true circular corner. The rounded corner feature on a rectangle gives a far more accurate circular corners.

    If you clone (ctrl+k) the circle, change it to a 4 sided polygon, there is nothing to move. The 4 corners sit upon the circle. ctrl+1 simply then adds the 4 requisite points. Less effort.
