3D graphics, CAD-CAM-CAE file extensions

3D graphics, CAD-CAM-CAE file extension list

List of file extensions used for 3D graphics file formats, related to 3D graphics software, CAD/CAM/CAE software and tools.

3D computer graphics file types are graphics files that use a three-dimensional representation of geometric data that is stored in the computer for the purposes of performing calculations and rendering 2D images or animations. Such images may be for later display or for real-time viewing. 3D computer graphics used many of the same algorithms as 2D computer vector graphics in the wire-frame model and 2D computer raster graphics in the final rendered display. In computer graphics software, the distinction between 2D and 3D is occasionally blurred 2D applications may use 3D techniques to achieve effects such as lighting, and primarily 3D may use 2D rendering techniques.

The most popular 3D graphics applications are 3D Studio MAX (3ds file extension [Autodesk]), Blender (blend file extension [Blender Fundation]), Cinema 4D (c4d file extension [MAXON]), LightWave 3D (NewTek), Maya (Autodesk), Rhino 3D and many others.

The term CAD/CAM/CAE is a shortening of Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) and Computer-Aided Engineering. The term CAD/NC (Numerical Control) is equivalent in some industries. CAD/CAM software uses CAD drawing tools to describe geometries used by the CAM portion of the program to define a toolpath that will direct the motion of a machine tool to machine the exact shape that was drawn.

The most popular CAD/CAM software are AutoCAD (dwg file extension [Autodesk]), Alphacam (Planit Solutions), ArchiCAD (Graphisoft), STAAD.Pro (Bentley), Catia, NX (formerly Unigraphics) etc..
