Abstract: Methods for product data management and corresponding systems and computer-readable mediums. A method includes receiving a geometric model including plurality of blends and identifying a blend ribbon that includes at least two of the plurality of blends. Each blend in the blend ribbon is mutually dependent on at least one other blend in the blend ribbon. The method includes selecting a blend ribbon breaker corresponding to the blend ribbon and designating a plurality of blends in the blend ribbon as reblendable blends, based on the blend ribbon breaker. The method includes reblending the reblendable blends to produce a modified geometric model and storing the modified geometric model.

Abstract: Methods for product data management and corresponding systems and computer-readable mediums. A method includes receiving one or more layer boundaries of one or more plies of a composite part. The method includes creating a topological definition from the layer boundaries, the topological definition includes one or more vertices and half-edges. The method includes identifying one or more vertical ramp sections of one or more vertical ramps from the topological definition that form one or more discontinuities in the topological definition. The method includes adding one or more additional vertices and half-edges to the topological definition based on the layer boundaries and the vertical ramp sections. The method includes creating one or more faces in the topological definition along the vertical ramp based on the additional vertices and half-edges to resolve the discontinuities. The method includes transmitting the topological definition with the faces.
