    摘要： A system, method, and computer program for modifying a solid model representation that is manipulated in a computer having software instructions for design, 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 accesses at least one data file having a plurality of geometric model definitions; converts the geometric model definitions into a visual representation of a geometric model; identifies an edit feature for modification on a body of the geometric model; calculates a modified geometric model with the modified edit, wherein the computer system removes the edit feature from an original body of the geometric model; creates a mapping for a plurality of faces from the edit feature to a new edit feature; applies the new edit feature to the original body, wherein the new edit feature is remapped to a new body and the new body is modified; and integrates the new feature with the modified geometric model; and appropriate means and computer-readable instructions.

    摘要： A system, method, and computer program product for performing edits on related curves by automatically defining an associative entity that is upstream of either curve being connected. The connecting entity is called an ‘intermediary’. When creating a connection between curves, irrespective of where they appear in the associative tree, their geometry is made dependent on a common intermediary that is placed upstream of both curves in the tree. With this structure, both curves are related to the intermediary but retain all the properties of being connected to each other. Any edit performed to either curve is redirected through the intermediary such that both curves are simultaneously modified, providing the user with bi-directional propagation of edits. The user does not need to keep track of the order that the curves were related.
