Perforated Solid Demonstrate the Jig, Organized Collection of Points and Place Holder pattern in a concise example. Demonstrate basic kinds of geometric objects: points, directions, lines, curves, surfaces and solids. Produce a curved solid with holes removed by set of cones. Use a Jig of points to define curves. Use a Jig of curves to define a surface. Offset a solid from the surface. Place an Organized Collection of Points on the surface. At each point, create a Place Holder of directions and lines. Use the Place Holder to define a collection of cones (solids). Reduce the collection of cones to a single solid. Difference the reduced solid from the offset solid.
