Convert SLDPRT to IPT

An Inventor-based project may require an .ipt file for assembly placement, drawing creation, or further editing. Converting the SolidWorks source avoids asking the recipient to install SolidWorks, but the result is usually imported geometry rather than a fully editable Inventor feature history.

What the SLDPRT format is

.sldprt is SolidWorks’ native part format. It can contain one or more solid or surface bodies, sketches, features, dimensions, configurations, materials, appearances, and custom properties. SolidWorks uses it for individual components supplied in engineering projects, manufacturing exchanges, and product libraries.

The feature history—such as extrusions, revolves, holes, fillets, shells, and patterns—is native to SolidWorks. A translator normally cannot reproduce that history as an equivalent, fully editable Inventor feature tree.

What the IPT format is

.ipt is Autodesk Inventor’s native part format. It stores Inventor part or sheet-metal bodies, sketches, parameters, features, materials, iFeatures, and related design data. IPT components can be placed in .iam assemblies and referenced by .idw or .dwg drawings.

Saving imported geometry as IPT gives an Inventor-managed component, but the result commonly contains a translated body or base feature instead of the original SolidWorks design intent. Inventor users can remodel critical features or use feature-recognition tools where appropriate.

How to convert SLDPRT to IPT

Autodesk Inventor

1. Copy the original .sldprt to a local working folder and keep it unchanged. Check the installed Inventor release and its SolidWorks translator support; older releases may not read files created by newer SolidWorks versions.
2. In Inventor, choose File → Open and select the SolidWorks part file. If necessary, set the file filter to SolidWorks Parts.
3. Review the import options offered by that Inventor release. Use an independent converted model for a standalone IPT. Use a linked AnyCAD or reference workflow only when maintaining a link to the SolidWorks source is required and supported by the project.
4. Inspect the imported body for missing faces, open surfaces, incorrect holes, fillets, threads, or other translation errors. Check important dimensions and mass properties against the SolidWorks source.
5. Choose File → Save As, select Autodesk Inventor Part, and save the file as part-name.ipt. Renaming .sldprt to .ipt does not convert the format.
6. Close and reopen the IPT, then insert it into a test Inventor assembly. Verify units, origin orientation, appearance, material, physical properties, and any downstream drawing references.

Menu names and import options vary by Inventor release. If direct opening is unavailable or fails, open the SLDPRT in SolidWorks and export it as .step or .stp. Import that STEP file in Inventor, repair or inspect the resulting geometry, and save it as IPT. STEP generally preserves solid geometry better than mesh formats such as STL, but not the native feature history.

Desktop batch translators

For multiple files, Datakit CrossManager is a specialist desktop translator that may convert SLDPRT to IPT without an Inventor authoring workflow. Confirm the current edition’s SLDPRT input and IPT output support before licensing it; format support depends on the product release and license. Test representative parts first, especially configurations, sheet-metal parts, and models with imported or complex surface geometry.

Online conversion

CAD Exchanger Cloud is an online option to check when its current service and plan support both SLDPRT input and IPT output. Upload a nonconfidential sample first and verify the downloaded file in Inventor. Many online CAD converters accept SLDPRT but export only STEP, IGES, STL, or other exchange formats, so do not assume that a listed SolidWorks input guarantees native IPT output.

Do not upload proprietary designs until the provider’s retention, deletion, access-control, and data-processing terms have been approved. For confidential or production-critical models, use Inventor or an approved desktop translator instead.

Quality and compatibility limits

• Feature history: translated geometry usually does not retain SolidWorks features, sketches, equations, mates, design tables, or design intent. Recreate features that must remain parametrically editable.
• Configurations: a translator commonly imports the active configuration. Open or export each required configuration separately and give each resulting IPT a distinct name.
• Assemblies: converting an SLDPRT produces a part, not an SLDASM assembly. Assembly structure, mates, suppressed components, external references, and component configurations require separate translation and verification.
• Special data: cosmetic threads, decals, appearances, weld information, custom properties, sheet-metal rules, and manufacturing metadata may be lost or altered. Recreate critical threads and sheet-metal settings in Inventor.
• Geometry: compare bounding-box dimensions, hole locations, volume, mass, and surface continuity. STEP can contain tolerance or surface-repair problems, and a visually correct model may still fail downstream machining, analysis, or drawing operations.
