Methods for accurately modeling blends in a solid model and corresponding systems and computer-readable mediums. A method includes receiving a solid model including a plurality of faces and bosses, and identifying a pocket from the plurality of faces, including one or more pocket edges to be blended. The method includes performing an analyze pockets process on the pocket and identifying at least one of a tool type, a tool method, or a tool dimension for machining the pocket. The method includes performing a blend pocket process to model blends on the pocket edges and adding blends to the solid model at the pocket edges in a predefined order, according to the blend pocket analysis, to produce a modified solid model. The method includes displaying the modified solid model by the data processing system.
