Autodesk Inventor, developed by U.S.-based software company Autodesk, is 3D parametric solid modeling software for creating 3D mechanical models. Autodesk Inventor is the foundation for the digital prototyping solution at Autodesk. The Autodesk® Inventor® product line provides a comprehensive and flexible set of software for 3D mechanical design, product simulation, tooling creation, and design communication that help you cost-effectively take advantage of a Digital Prototyping workflow to design and build better products in less time. With Inventor, you create digital objects that simulate physical objects. Inventor models are accurate 3D digital prototypes. With the parametric modeling tools in Inventor, you can apply driving dimensions and geometric relationships to an object. The size and shape or geometry of an object depends upon dimensions and relationships to other parts. When one part is changed, the object automatically updates to reflect the change.
