Hello Ed,

If I get you right you can do something like that:

- place a point on the curve from you would start with your coordinatefile.

- make a transform-> array -> curve with the point as object and your circle as path curve, choose the resolution you want:-)

- select all points and run the script from http://kyticka.webzdarma.cz/3d/moi/#SavePointFile (put the 2 files in command and make shortcut key under options)

- share your results with us and make us happy:-) and give us inspiration:-)

Good luck
Karsten
