3D modeling is a process that uses computer software to develop a three dimensional representation of an object. The resulting object is a 3D model of the original object. Engineers use 3D models to perform a wide range of testing, simulations and analysis to answer questions and solve problems.
3D modeling and models are used in a wide variety of fields and industries. For example, doctors view 3D images of organs to support their diagnosis, architects use them to layout and design building, the movie industry use them to create animation and the engineering community use 3D models to design products, structures and perform safety and fault tolerance analysis.
Engineers use 3D models to run 3D crash test simulations between vehicles and road barriers. In an effort to produce better cars, engineers create 3D models of vehicles and barriers and then run crash test simulations of cars hitting barriers to analyze the effects.
Among the many engineering applications for 3D modeling, safety applications are on the top of the list. Engineers must meet a variety of design specifications, requirements and tolerances including quality and safety requirements. To meet these requirements, engineers use 3D modeling to model, simulate and refine their designs.
