The IPT file format is associated with Autodesk Inventor, a CAD (Computer Aided Design) application developed by the US based software company Autodesk. The application is used for three dimensional digital prototyping. Its main purpose is the simulation and visualization of products before they're built.

IPT (Inventor Part) files are used to store the data for a single 3D or 2D object. This file format is one of the primary ones used by Inventor and it is only used for the smaller parts of the product that do not move. These can be all put together with others in Inventor to form the end product.

IPT Files can be created and edited with Autodesk Inventor or imported into the application as parts of a larger product. Autodesk Inventor is only available on the Microsoft Windows Platform.
