The mold design system SMDS which was presented at the first report has conversational functions to build up a mold object. This paper describes the method of building up a 3-dimensional object by interactive operations in SMDS. The concept of geometric modeling in this system is based on solid modeler TIPS-1 system. In the TIPS-1 system, 3-dimensional shape is described by TIPS-1 shape description language and represented by set operations of several segments. And geometric data are generated by batch process. In this paper, a theoretical approach to the interactive object modeling is discussed. Secondly, the algorithms are described that realize the interactive object modeling and also output shaded pictures of the object on a raster-scan display. And some results of shaded pictures are presented.
