- The technique for creating the development of solids is determined by the
basic geometric shape. Prisms, pyramids, cylinders, and cones each have a particular
- The intersection of two solids is determined by plotting the intersection
of each surface and transferring the intersection points to each development.
- Cones and pyramids use radial development. Prisms and cylinders use parallel
- Truncated solids, cones, and pyramids are created by developing the whole
solid and then plotting the truncated endpoints on each radial element.
- Transition pieces are developed by creating triangular surfaces that approximate
the transition from rectangular to circular. The smaller the triangular surfaces,
the more accurate the development.
