What Autodesk Inventor is

Autodesk Inventor is Windows software for 3D mechanical design, documentation, simulation, and model-based definition. Its modeling approach combines parametric, direct, freeform, and rules-based methods, with tools for assemblies, sheet metal, and surfaces. Inventor can open designs from other CAD systems without translation, and its documented format support includes numerous export options for parts, assemblies, and drawings. It connects with Revit family data, Vault, Factory Design Utilities, and Inventor Nastran; automation options include iLogic, its API, and Autodesk Platform Services. A subscription permits installation on up to three devices, but only the named user may use it on one computer at a time. The software is paid and has a 30-day trial, not a permanent free tier. Monthly, annual, and three-year price displays are placeholders rather than figures. Annual and multi-year subscriptions have a 30-day return policy; monthly subscriptions have 15 days.
