Autodesk Inventor competes directly with SolidWorks, Solid Edge, and Creo. Autodesk Inventor Professional is also a part of a collection license Autodesk Product Design & Manufacturing Collection. The software can be licensed as a subscription or through pre-paid Flex Tokens (daily use, consumption-based). Inventor uses ShapeManager, Autodesk's proprietary geometric modeling kernel. Autodesk Inventor includes parametric, direct edit and freeform modeling tools as well as multi-CAD translation capabilities and in their standard DWG drawings. Inventor allows 2D and 3D data integration in a single environment, creating a virtual representation of the final product that enables users to validate the form, fit, and function of the product before it is ever built. Autodesk Inventor is a computer-aided design application for 3D mechanical design, simulation, visualization, and documentation developed by Autodesk.
