1. A method for visually verifying a design of a wire system, said method comprising using a computer to: retrieve logical design data associated with the wire system, and physical design data associated with the wire system; extract data from a 3D computer model of the wire system; convert the retrieved logical and physical design data and the extracted data into a common data format; perform a difference analysis of the logical and physical design data with the extracted data from the 3D model to identify any non-conformances between the 3D model and the design data; and graphically display any non-conformances.
