1.4 MANIPULATING SOLID MODELS OF DESIGNS

It was decided to use the non-uniqueness and global nature of the CSG representation to drive the logic of the BCAPP planning system. But, in addition to this the CSG expression will be represented with Boolean expressions to allow use of Boolean algebra. This section will describe my particular representation. The following sections will discuss implementation of this representation in a Boolean Algebra program, and representing product designs with Boolean equations of sets.
