Abstract: A computer-based method is disclosed for identifying a parting line for molding a real-world part based on computer model of the part. The method includes receiving a computer-based representation of a modeled part and a parting direction for the mold to make a real-world version of the part. Then a computer-based processor characterizes each respective one of a plurality of faces in the computer-based representation of the modeled part as a positive draft face or a negative draft face. The method includes identifying, as at least a segment of the parting line, a boundary edge between a first one of the positive draft faces and a first one of the negative draft faces that neighbors the first one of the positive draft faces.

Abstract: A computer-implemented method and system uses a single command to modify a feature type of a feature in a computer-aided design model. The method and system construct a three-dimensional (3D) model comprised of at least one feature, where the feature type is an extrude, a revolve, and a sweep. A command is provided that upon execution creates an extrude feature, a revolve feature, or a sweep feature. The feature is modified such that the feature changes from one feature type to another feature type. And after modifying the feature, references to a set of faces of the feature are maintained such that other features dependent on the feature properly update.
