In a computer aided design system, a method for converting a computer-generated symbol, or computer generated graphical entities, into an intelligent symbol involves identifying connection points to the computer-generated symbol and generating coordinates for the connection points. A symbol definition is built using the coordinates. The connection points are found by determining a perimeter substantially including the symbol and identifying graphical entities on or near the perimeter. Connectors joined to the symbol are also converted into intelligent connectors by finding coordinates for points on the connectors. A multi-symbol is generated from two or more symbols. The definition of one of the symbols forming the multi-symbol is maintained and linked to the multi-symbol such that changes in that symbol are reflected in the multi-symbol.
