Disclosed is an apparatus for comparing CAD (computer aided design) design data comprising one or more components with a set of design rules generated relative said components and generating an output report of detected discrepancies. The output may include data (annotations) used to generate a visually high-lighted (red-lined) display whereby the CAD generated design errors may be easily ascertained. The apparatus includes the capability of transmitting the CAD data, converted to a standardized XML format, from a remote CAD design site to a difference engine site having the latest set of rules relative said components. The difference engine site may then return the results to the remote CAD design site for use by the device design operator. The results returned may be visually displayed in red-lined format as well as in an itemized list.
