3D Geometric Modeling

In product design, the goal of design process is to completely and accurately specify necessary information of the components that meets design specifications. Among all the necessary information, specifications such as material and surface finishes can be easily specified. Geometric information, however, is the most complicated and important aspect to communicate. To define the three dimensional (3D) geometric information precisely, you will use 3D computer models. By using unambiguous 3D models, you can eliminate misunderstanding in downstream processes and facilitate manufacturing of components as designed.
