This is another simple visualization tool we use:  Microsoft's Paint.  Microsoft says, "Paint is a program used to draw, color, and edit pictures. You can use Paint like a digital sketchpad to make simple pictures and creative projects or to add text and designs to other pictures, such as those taken with your digital camera."  The black and white line drawing here is done using our cabinet drafting software - expensive, complicated, long learning curve and a very frustrating but necessary part of doing business as a cabinet dealer.  Microsoft's Paint on the other hand is free, simple and intuitive.
