Abstract: A method for generating a computer model of a composite component includes generating a surface mesh based on a ply drop region and a ply curved surface and generating node data including a plurality of node points relative to the ply drop region. The method also includes receiving composite data relating to a plurality of composite plies and generating a three dimensional model based on the composite data. The method further includes receiving layup table information and applying the node data, based on the layup table information, to generate a curve through a center of the surface mesh to define a plurality of element sets. The method also includes receiving composite draping data and determining, based on the draping data, where each element set intersects the three dimensional model. The method also includes analyzing an angle deviation of the plies based on the intersection of the element sets.
