Project File (.ipj, Inventor)
Inventor's project definition — sets workspace, content centre paths, library locations, units, and templates.

Definition
The .ipj is the master project descriptor. It defines Workspace (where new files go), Workgroup Search Paths (where Inventor looks for referenced files), Libraries (read-only folders), Content Center Libraries, and project units. Inventor must have an active .ipj to open files; activating a different project changes where references resolve.
Why it matters
Without a properly configured .ipj, Inventor reports missing references for every file the project references. Multi-user projects need a shared .ipj on a network or in Vault.
Common pitfalls
- Working in 'Default' project for production files — references break when moved.
- Inconsistent project files across the team — same file opens differently for different users.
- Forgetting Vault Workgroup checkin invalidates local .ipj definitions.
Inventor Ecosystem Context
This concept is a core structural element of the Inventor drafting and engineering environment developed by Autodesk. Autodesk's Windows-native parametric MCAD — strong on large mechanical assemblies, sheet metal, frame generator, and integration with Autodesk Vault and Revit.
Relevant Inventor FAQs
❓ What's the difference between Inventor and Fusion 360?
Inventor is Windows-only desktop, file-based, deep MCAD with Vault integration. Fusion 360 is cross-platform (Win/Mac), cloud-data, broader scope (CAM, electronics, generative design), simpler assemblies. Inventor for established mechanical engineering teams; Fusion 360 for makers, small teams, integrated CAM workflows.
❓ Can Inventor open SOLIDWORKS files?
Indirectly. Inventor doesn't natively read .sldprt/.sldasm; export from SOLIDWORKS to STEP or Parasolid, then open in Inventor. Features import as static geometry without parametric history.
❓ What's in the Product Design & Manufacturing Collection?
Inventor, AutoCAD, AutoCAD Mechanical, Inventor Nastran (FEA), Inventor Tolerance Analysis, Factory Design Utilities, Inventor CAM, Vault Basic, ReCap Pro, and Fusion 360 (selected modules). Most production Inventor users are on PDMC rather than standalone Inventor.
