CAD 3D modeling allows us to create drawings using solid, surface, and mesh objects. Each has a different functionality. For instance, a mesh object lets us take advantage of creasing and smoothing, while a surface model will let us take advantage of associatively and NURBS modeling. We can also convert one model type to another. A typical modeling workflow would use using mesh, solids, and procedural surfaces, and then convert them to NURBS surfaces. This allows us to utilize not only the unique tools and primitive shapes offered by solids and meshes.

3D modeling has revolutionized the design, manufacturing, research & development, and the advertising industries. With 3D modeling, it is now possible to visualize an outcome even before it is given a practical, real shape. 3D modeling allows inventors and designers to evaluate their concepts and to identify potential flaws that may lead to project failure at a later stage. These s provide details about the various types of 3D modeling techniques and their specific uses and applications.
