Autodesk Inventor vs Onshape

Autodesk Inventor is Windows software for mechanical design, documentation, simulation, and model-based definition. Its 3D tools combine parametric, direct, freeform, and rules-based modeling, with support for assembly design, sheet metal, and surfaces. Inventor can open designs from other CAD systems without translation. Parts can be exported to formats including DWG, IGES, JT, OBJ, STEP, and STL; assembly exports also include RVT, while drawings support DWG, IDW, DWF/DWFx, and DXF. Design connections include Revit family data, Vault, Factory Design Utilities, and Inventor Nastran. Automation options include iLogic, the API, and Autodesk Platform Services. Inventor is paid, with a 30-day trial and no permanent free tier. Displayed monthly, annual, and three-year prices are placeholders, not figures. A subscription permits installation on up to three devices, but only the named user may sign in and use it on one computer at a time.

Onshape is a browser-accessible 3D CAD platform for parametric modeling of solids, surfaces and sheet metal, with iOS and Android apps also available. It supports assembly design, rendering, simulation, CAM and 3D-print export. Simulation covers linear static and modal analysis for stress, deformation and natural frequencies; CAM supports machining from 2.5-axis through 5-axis machines. Collaboration includes multi-user editing, instant sharing, real-time communication and access controls. Built-in product data management includes edit history, version control, release management, search and design-data sharing. The Free Plan is for non-commercial use, with publicly accessible documents and unlimited public storage. Standard costs $1,500/user/yr; Professional costs $2,500 per year. Qualified professionals may be eligible for a Professional trial of up to six months without a credit card. Enterprise uses custom pricing. Onshape says updates arrive every three weeks without installations or downtime. Listed integrations include Slack, Arena PLM, Altium Designer, FeatureScript, REST API and the App Store.
