Files with the IDW extension identify 2D image files created in the IntelliDraw application. IDW files contain vector graphics that are made up of simple geometric shapes such as points, curves and lines. IDW files may be opened and edited with compatible design software applications.
The IDW file extension is associated with AutoDesk Inventor, a 3D modeling design software used to create third-dimensional digital prototypes for design, visualization and simulation of other products, continuously developed by AutoDesk since 1999. IDW is the default format for CAD drawings created in AutoDesk Inventor.
