Speaking of the masters, Harry once again gives a nod to Watson Kilbourne, who supplies some of the best hatch patterns. You can use his latest, c-stone.pat (Tip #1960, Course Bricks and Stone Hatch), to draw coursed bricks or stone patterns. Keep in mind that if you submit applications that create drawings, I test them using AutoCAD 2005 in a blank drawing. Your application should include everything needed to set up layers, line styles, and any other drawing specifics. When others download your code, it will run in foreign environments and your application should assume nothing is right.
