An Advanced Parametric Modeling Based on Feature

The modeling process of fillet and architrave is complex and time-consuming.In this paper,a new efficient modeling algorithm is proposed following the architectural principle of polyline.A definition and auto-generation of the fillet section are obtained through a definition of closed polyline and a parameterized description of its properties.With the B-rep of ACIS,the UCS of section is obtained intelligently by automatically selecting loft paths and adjacent edges.Our experiments with OOP and ObjectARX indicate that the proposed approach can efficiently improve the performance of the modeling process.
