This question may be in the wrong section but its probobally the most suitable.

I have a series of short lines that form a curve (it happens to be a Bezier curve). Can anyone tell me, or at least point me in the right direction, how to
generate a series of arcs based on these lines so that the curve is made up of a series of arcs. (The idea being that if the Bezier curve is made up of say 1000 lines it may be reduced to being represented by say 100 arcs).

Adobe Illustrator is your best bet. Select the curve, add a whole batch of points and then convert the whole thing to straight lines instead of curves.

I think you've misunderstood me. I already have the series of lines but I want to reduce them to a series of curves

Ahhh that is quite a bit more complicated. Youll have to redraw them with a bezier curve tool (Illustrators Pen Tool). No program is going to recognize a series of lines as a whole curve and convert it automatically.

In Macromedia Freehand you can do this...IMHO its bezier capabilities are way superior to Illustrator .....

Select the points on the line (make sure youve created one line with many points and not a load of separate lines)by dragging a marquee around it or if you want press shift and alt and click on each point.
When youve got them all selected open the Object inspector (Ctrl-I)and click on the point type button that has two curves coming out of the point.
At the bottom of the object inspector window you have nifty little check box marked Automatic, when you click it you'll see you're straight lines turn to curves...the quality of the curves will depend on the uniformity of the points on the line....if youre not happy with the results keep trying....the other alternative is to draw the curve using the pen tool...not so easy, but ultimately the best way to do it. You can for example create a perfect semicircle with only three points!!
