To check an illustration for “errors” in a computer illustration program use the reflect tool. For example: I frequently draw “big hair’ on the right side of a subject, flipping the drawing exposes this nicely! (If you’re drawing on paper, flip it around and hold it up to the light.) – Susan Haug, Product Developer, Henderson, MN, USA
A cool tool is anything useful that is superior to comparable items. If you think this tool is inferior suggest a better one. You are welcome to insult a tool, but comments containing insults to individual people will be deleted. Corrections of fact are always welcomed, if stated politely. Recommendations of better tools are dearly wanted and may be elevated to the front page.
