Presentations (.ipn, Inventor)
Animated exploded-view files derived from an assembly — used for assembly instructions and animations.

Definition
An IPN file references an IAM and adds tweaks (offsets, rotations) to components, creating an exploded view. Snapshots define key positions over time; an exploded-view animation interpolates between snapshots. Output: animations (AVI, MP4), exploded-view drawings, and lightweight web-viewable presentations.
Why it matters
Assembly instructions need exploded views; service manuals need them animated. Presentations produce both from one file linked to the assembly.
Common pitfalls
- Static tweak values — when the assembly changes, tweaks no longer align.
- Long animations with many snapshots — file becomes unwieldy.
- Forgetting to link to current assembly version — IPN shows old geometry.
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.
