Modifying constrained and unconstrained curve networks

摘要

Methods for modifying geometric models and corresponding systems (100) and computer-readable mediums (126). A method includes receiving (205) a geometric model (100), the geometric model including a plurality of curves (302/304a/304b/306a/306b). The method includes receiving (210) a selection of one or more curves of the plurality of curves, finding (215) at least one other curve of the plurality of curves that is related to the selected curve, and finding relationships between the selected curve and the other curve(s), including adding the selected curve, the other curve(s), and the relationships to a selected curve set. The method includes pre-processing (220) the selected curve set, including de-activating a set of constraints for the geometric model. The method includes receiving (225) a modification of the selected curve and modifying (230) the selected curve set to produce a modified geometric model and modified selected curve set. The method includes post-processing (235) the modified selected curve set, including re-activating and applying constraints for the geometric model.
