How to Export Files from SOLIDWORKS to Inventor

To move a SOLIDWORKS model into Autodesk Inventor, export the model in a neutral CAD format that Inventor can open. STEP is usually the best starting point for solid parts and assemblies because it preserves clean B-rep geometry better than mesh formats.

Choose the export format

Use STEP for most parts and assemblies. Parasolid may also work well depending on your Inventor version and workflow. IGES can be useful for surfaces, but it may require more repair. Avoid STL unless Inventor only needs the model as a mesh reference.

If the receiving user only needs to measure, review, or place the model, ask which format their Inventor setup handles best. If they need to edit the geometry, STEP or Parasolid is usually a better choice than a mesh.

Export from SOLIDWORKS

1. Open the part or assembly in SOLIDWORKS.
2. Rebuild the model and resolve missing references.
3. Choose File > Save As.
4. Select STEP, Parasolid, or another required neutral format.
5. Open Options and confirm the export settings.
6. Save the file to a location Inventor can access.

Open the file in Inventor

In Inventor, open or import the exported file and review the import options. Large assemblies may take time to translate. After import, save the file in Inventor format so future edits and drawings use Inventor files instead of repeatedly importing the neutral file.

Check the translated model

After import, inspect the body count, assembly structure, units, orientation, and important dimensions. Check holes, threads, sheet metal features, and patterned parts because translation can simplify feature history.

Neutral exports usually bring geometry across, not the full SOLIDWORKS feature tree. Plan to edit the imported model as translated geometry unless you have a specialized feature-recognition workflow.

For critical parts, compare a few known dimensions against the original SOLIDWORKS model. This is a quick way to catch unit, scale, or translation mistakes before the file is used downstream.

Prepare files for sharing

If you are sending files to another company, include the exported file, the original revision information, and any notes about suppressed components or configurations. For assemblies, confirm that the exported file includes the intended configuration and visible components.

When an assembly has vendor parts or purchased components, decide whether those should be included, simplified, or removed before export. This can reduce file size and avoid sharing unnecessary detail.

Troubleshooting

If Inventor reports missing or bad geometry, try exporting STEP AP214 or AP242, simplify the SOLIDWORKS model, or export problem components separately. If units are wrong, verify the units on both the SOLIDWORKS export and the Inventor import.
