METHOD AND SYSTEM FOR APPLYING CONSTRAINTS TO CHAINS OF CURVES |
摘要 |
A method and system for applying constraints to a wireframe chain of curves for Computer-Aided Design (CAD) is disclosed, whereby a geometric constraint network can be expanded to include chains of curves as types of wireframe entities. As such, a chain of curves can be represented as one composite curve. As a result, a constraint solver can generate and/or maintain any constraint on a chain of curves, which enables theconstraints to be solved while moving along the curves independently from the chain's geometry and topology changes.
