One of the most interesting features available in all 3D computer graphics programs is the capacity to emulate forms produced by a lathe. In SketchUp the "follow-me" function is most often used for this purpose. A 2D cross-section of a form is drawn, and that is then spun around a central axis to produce the rounded 3D form. While one can thus produce round vase-like objects, the process is also useful for creating new shapes and surfaces through the intersection and joining with other shapes.
The pawn figures were actually an intermediate step in the creation of a thumb-latch in the model I am working on at present. After spinning the form, I sliced it vertically through the middle, and then laid it over on the newly-created flat surface. I like the simple elegance of the unaltered form, however, and perhaps I'll use it as-is in some future composition.
