A symbol is a graphical object that [[RF.Spice A/D]] uses to represent a part or device. Every device in the Parts Database has an associated symbols. Some devices may have more than one associated symbol. When you place a part in your schematic, its symbol is drawn in the schematic window. You can move a part in your circuit by selecting and dragging its symbol around. A symbol is typically made up of a drawing, one or more texts and one or more pins. The drawing can be as simple as a box or a circle or very sophisticated graphics. The Symbol Editor provides a number of drawing tools: Line, Rectangle, Ellipse, Polygon and Arc. A symbol may contain a composite drawing involving several distinct shapes. The symbol's text(s) may include the device name and a number of parameter values.
