Nearly all commercial products start as a CAD file — a 2D or 3D model with the product’s design specifications. One method that’s widely used to represent today’s 3D models is constructive solid geometry (CSG), a technique where numerous basic shapes (primitives) with a few adjustable parameters can be assembled in various ways to form a single object. When finalized, the compiled digital object is converted to a mesh of 3D triangles that defines the object’s shape. These meshes are used as input for many applications, including 3D printing and virtual simulation.
