Alan, how to reverse start and end point of arc??? I thought there was a way without lisp? i.e. to initially construct said arc?

Yeah, just joined the site today and it looks great. Another question: is there a visual way to display the direction of lines (like an arrow or some other indicator), prior to changing the direction?

A "quick" way could be to temporarily set the line to a complex line type with a V rotated to point in the direction of the line. Otherwise you could add something in lisp which just draws an arrow representation using something like grdraw.
