Aye, I've tried various methods to improve the output and zero'ing the fractal factor combined with keeping the line sections short was the approach I found worked best with the freehand tool.
The Spline tool worked okay for outlining features - as you say, Beowulf, more points and short sections . The polygon tool has potential too, tho' the fact that it defaults to filled is a hinderence when you're trying to overlay on top of an import .
Amongst my major gripes at the moment, other than those previously alluded to, is the lack of a proper cursor-tip scroll tool that doesn't lose it's focus on the last in-screen point clicked. Again maybe it's just that I'm not using it correctly but I find when I'm zoomed in tracing an intricate 'wiggle' of terrain and have to scroll then the tool adds a point on the map adjactent to the area of the scroll bar I grabbed to move the viewport - so you click undo and it removes the new point, loses the focus and, for all I know, the whole line disappears :grr:.
I'm sure that if I use it more I'll begin to find ways to achieve the results I'm after (either by amending my approach or uncovering options I haven't yet seen). I think what's throwing me at present is that FM is neither a CAD nor image-manipulator package but something in between - I need to find the line (yeah, mapping pun (sort of )) to walk that matches that balance.
