Abstract: Methods for performing geodesic edits and corresponding systems and computer-readable mediums. A method includes receiving a CAD model including at least a three-dimensional (3D) surface. The method includes receiving an edit of a first geodesic feature from a user and in response to the edit, performing a hierarchy-based update to the CAD model, including performing a corresponding edit to at least one other feature of the CAD model based on the edit to the first geodesic feature to produce an updated CAD model. The method includes storing the updated CAD model.

Abstract: Methods for CAD modeling and corresponding systems (100) and computer-readable mediums (126). A method includes receiving (505) a solid model (200) including a plurality of parts and receiving (510) a selection of a first part (210) and a second part (220) of the solid model. The method includes identifying (515) an interference (230) between the first part and the second part and determining (520) a step feature modification (240) to the first part based on the identified interference. The method includes modifying (525) the first part to add the step feature modification to create a modified solid model (250) and storing (530) the modified solid model.

Abstract: 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 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 edge and adding a blend to the solid model at the pocket edges, according to the blend pocket process, to produce a modified solid model. The method includes displaying the modified solid model by the data processing system.
