Abstract
This research aims to propose a new approach tea modelling solid shapes, ca lled qualitative solid modelling, for supporting conceptual mechanical desi gn. In a previous paper, a method has been described to represent qualitati vely the simplified shapes of solids whose surfaces are all planes and perp endicular to the axes of the given orthogonal coordinate system. A qualitat ive solid model is defined as a domain network that has domains (cuboids) a s its nodes and qualitative spatial relations among the domains as its link s. This paper details a number of qualitative solid operations, ranging fro m the most basic declarations of domains and domain relations to qualitativ e set operations of domains, that can be combined to facilitate tasks of mo delling complex qualitative solid shapes in computers. All operations menti oned in this paper have been implemented in a qualitative solid modelling s ystem, called QuaSMos. The validity and efficiency of several important qua litative solid operations and the qualitative solid modeller QuaSMoS are co nfirmed with an example of complex solid shapes.
