An improved system and method are designed to take engineering composite drawings released in a computer-aided design (CAD) data set, determine the attributes of each of a plurality of plies into its composite drawing, and pass the information on to using organizations. In preferred embodiments, the system logically determines the geometric definitions for each ply contained in a composite part and reports any errors to the user. Analysis of the physical properties of a part is also provided. Computation of the total part weight and centroid location is performed by the system. Additionally, the present invention creates detailed engineering models of each composite ply and passes information directly to manufacturing.
