3D models represent an object using a collection of points in space. These points can be connected by various geometric entities, such as triangles, lines and curved surfaces. 3D models can be created by hand, algorithmically, or scanned. NCG can provide clients with 3D models in numerous export formats such as .OBJ, .STL and .DWF. 3D objects can be used in the design of HVAC systems, car accident simulations, sewer pipe design, and many other applications.
