Abstract:
1. A method performed by a CAD data processing system and comprising: receiving a boundary representation (BRep) model; recognizing a plurality of notch blends in the BRep model; defining a chain of at least two of the plurality of notch blends; labeling the notch blends in the chain, including generating a blend radius corresponding to each notch blend, a topological under corresponding to each notch blend, and a location, a size, and an orientation of a consumed under corresponding to each notch blend; and storing the BRep model, including one or more of the recognized notch blends, the chain, and the labels of the notch blends. wherein the data processing system also defines a virtual face corresponding to one or more of the notch blends, and wherein the data processing system also changes the virtual face and updates the corresponding one or more notch blends according to the change to the virtual face.
