Or Bezier curves?
No. We are talking drawings here.

Wow, all of you guys interested in curves!!
So, I've used arcs where a true arc seems to match, polylines for sections with longer straight elements and splines for the rest.
I've found that when trying to accurately trace the original, zooming in obviously gives you the problem of a pixelated image, so splines are handy to pick a multitude of points that can then be pulled to smooth out the outline.
I'll join it all into one polyline once I'm happy with the editing.

You can curve a polyline by entering "a" on the keyboard whilst using the polyline. Go back to straight line by pressing "l"

Hi Cliff,
absolutely, the use of the 'a' on the command line once the polyline is selected works very well. It basically turns the polyline into a variable arc, and the vertices you pick on the trace outline are then available to edit.
Out of curiosity, what programs do you currently use?
Sean.
