Abstract: Methods for CAD operations and corresponding systems and computer-readable mediums are disclosed herein. A method includes receiving 3D solid model data of a part to be manufactured, receiving at least one rule from a rules database, applying the rule to the 3D solid model data using a rules engine, and producing an output according the rule applied to the 3D solid model data. The rule can include an extraction portion which identifies elements or features of the 3D solid model data, a logic portion that applies a condition to the identified elements or features, and an action portion that defines an action to be performed to identified elements or features that meet the condition. The output can include an annotation of product manufacturing information to elements or features of the 3D solid model data that match the rule.

Abstract: Methods for product data management and corresponding systems and computer-readable mediums. A method includes receiving a geometric model including plurality of entities and receiving existing conditions corresponding to the geometric model. The method includes receiving an operation to be performed on a selected entity of the geometric model. The method includes propagating through the geometric model from the selected entity to other entities of the geometric model, according to the existing conditions, and adding the selected entities and the other entities to a variational system. The method includes performing a variational solve of the variational system according to the operation to produce modified entities and applying the modified entities to the geometric model to produce an edited geometric model.
