Autodesk Inventor is a 3D computer-aided design (CAD) software used for product design, simulation, and visualization. It is primarily used in manufacturing, engineering, and product design industries to create detailed 3D models of products or parts, which can be used to test and validate their performance and functionality. Inventor offers a wide range of tools for creating parts and assemblies, including parametric design, sheet metal design, and simulation tools. It also supports collaboration and data management, allowing teams to work together on designs and track changes throughout the product development process. Inventor is a powerful tool for creating detailed designs and visualizations, making it a popular choice for product design and engineering professionals.
