In a computer aided design system, an intelligent symbol is made up of graphical entities. Connectors join the entities to other entities at connection points. When the symbol is moved, the connectivity between entities must be maintained. A connection point positioning symbol is generated, forming part of a definition of the intelligent symbol. The connection point positioning symbol has a position and an angle which describe the connection point. The connection point positioning symbol can be displayed and then hidden from view. The connection point positioning symbol allows the user to edit a connection to the intelligent symbol.
