Abstract: A system, method, and computer program for selecting modifications to a solid model that is manipulated in a computer having software instructions, comprising a computer system, wherein the computer system includes a memory, a processor, a user input device, and a display device; a computer generated geometric model stored in the memory in the memory of the computer system; and wherein the computer system selects a selecting point on a modification feature directly on a solid model using a computer peripheral input; sorts by distance a plurality of adjacent faces that are adjacent to a selection face determined by the selecting point; determines whether a convex condition exists wherein the plurality of adjacent faces are convex to the selection face; determines whether a candidate curves exists where the plurality of adjacent faces share a same surface with a previously visited face and the convex condition exists; imprints the candidate curve on the solid model to prepare the solid model for modification ac

Abstract: A method, system, and computer readable medium for identifying wall features in an object model represented in a CAD system. A method includes loading an object model in a CAD system and receiving a selection of a first face of the object model by the CAD system. The method includes finding candidate wall faces by the CAD system and storing the candidate wall faces in a candidate list, and designating at least one candidate wall face in the candidate list as a counterpart face to the first face. The method includes storing the first face and the counterpart faces as a wall of the object model. Some methods include removing at least one second face from the candidate list based on an exclusion rule.

Abstract: An interactive design system includes a design application that creates and models a geometry of an object. A programming language application defines engineering rules that may be associated with the object. The programming language application associates the geometry of the object with the engineering rules such that any change made to the geometry is automatically reflected in the engineering rules and any change made to the engineering rules is reflected in the geometry. The programming language application may also generate one or more knowledge features that can be used to verify that associated parameter constraints have not been violated as a result of a geometry or engineering rule change before applying the desired changes.
