A graphics program used for creating illustrations. It maintains an image in vector graphics format, which allows all elements of the picture to be isolated, moved and scaled independent of the others. Drawing programs and CAD programs are similar; however, drawing programs usually provide a large number of special effects for fancy illustrations, while CAD programs provide precise dimensioning and positioning of each graphic element in order that the objects can be transferred to other systems for engineering analysis and manufacturing. Examples of popular drawing programs are Adobe Illustrator, CorelDRAW and Macromedia Freehand. Contrast with paint program. See graphics and diagramming program.
