Feature-based modelling system based on sweeping operation technique

This paper presents a feature-based modelling system (FMS) which is an integrated geometric modelling system that supports both feature-based modelling and feature recognition. The presented system is based on the shape feature language ([6], [7], [8], [16], [15]) and sweeping operation technique ([9], [11], [13]). Each sweeping operation is a two stage process comprising: volume generation followed by a Boolean operation, whose complexity has been reduced from 3D to 2D. Both stages are internally represented by means of primitive operations, being Euler operations. Each modelled part is stored in two representations: an extended boundary representation (B-rep), and in a graph representation (Feature Volume Graph [9]).
