To me it doesn't really matter how someone figures there curves but for myself, I always figure curves in radius. It is verry simple to draw, lay out and figure. The thing that folks DO need to do though is, whenever they are writing in these forums, specify what unit of measure they are using, be it radius, diameter, MM, chains or whatever. That way we aren't guessing. I find it somewhat annoying when they reference a 10' circle and always wonder if they mean radius or diameter.
