Part and assembly files from other CAD systems can be imported for use in Autodesk Inventor Fusion. The import operation does not maintain associativity with the original file. Changes to the original file after the import operation do not affect the imported part or assembly. Likewise, changes to the imported part or assembly do not affect the original file.
When assemblies are imported, Autodesk Inventor Fusion attempts to preserve the assembly and subassembly structure of the original file. However, for SAT files, the subassembly structure is decomposed so that all subassembly parts become components of the top-level assembly.
The import process creates base features in Autodesk Inventor Fusion representative of the geometry and topology in the source file. You can use Autodesk Inventor Fusion commands to adjust the base features and add new features to the Autodesk Inventor Fusion feature tree.
Translate files into Autodesk Inventor Fusion data
You can open or import part and assembly files from other CAD systems.
To translate a file In Autodesk Inventor Fusion

Open and change models created in CATIA V5 (versions R6 - R20). Autodesk Inventor Fusion translates assembly and part files, solids, multi-solids, surfaces, and more. After the import operation is complete, you have a base feature or features that match the geometry and topology of the original file. Use commands in Autodesk Inventor Fusion to adjust the base features and add new features to the feature tree.
Types of CATIA V5 files you can import:
Open and change models created in Pro/ENGINEER and Creo. Autodesk Inventor Fusion translates assembly and part files, solids, multi-solids. After the import operation is complete, you have a base feature or features which match the geometry and topology of the original file. Use Autodesk Inventor Fusion commands to adjust the base features and add new features to the feature tree.
Types of Pro/ENGINEER files you can import:
Types of Creo files you can import:
Open and change models created in SolidWorks up to version 2011. Autodesk Inventor Fusion translates assembly and part files, solids, multi-solids. After the import operation is complete, you have a base feature or features which match the geometry and topology of the original file. Use Autodesk Inventor Fusion commands to adjust the base features and add new features to the feature tree.
Types of SolidWorks files you can import:
You can import a STEP file (versions AP214 and AP203E2). The solid body is saved in an Autodesk Inventor Fusion file, and no links are maintained to the original file.
If an imported STEP file contains one part, it produces an Autodesk Inventor Fusion file with a single body. If it contains an assembly, it produces an Autodesk Inventor Fusion file with multiple components.
You can import a SAT file (versions 4.0 - 7.0). The solid body is saved in an Autodesk Inventor Fusion file, and no links are maintained to the original file.
If an imported SAT file contains a single body, it produces an Autodesk Inventor Fusion part file with a single body. If it contains multiple bodies, it produces an Autodesk Inventor Fusion File with multiple components.
