Principal Elements of Solid Modeling

Three-dimensional basic solids generated by linear sweeping of primitives are presented to demonstrate that when stored as a script file, every detail involved in the linear sweep can then be listed. A linearly tapered fillet serves as an example to depict the boolean operations. For better visibility of a solid, splitting the display screen into multiple windows for showing various projects of the solid when viewed from different angles, the hidden-line technique, and changing the location of light source(s) in addition to an ambient light are also described.
