Upload and inspect your model
Upload a supported file or a ZIP containing the root assembly and its referenced components. The workspace provides the currently validated conversion formats.

Autodesk Inventor to STEP Converter Online
Convert Autodesk Inventor IPT / IAM to downloadable STEP online. Reuse an uploaded part or packaged assembly; incomplete geometry is flagged and feature history is not restored.
No account required
Temporary workspaceCAD processingBefore you use the result
Know what you are looking at.
Open Autodesk Inventor IPT, IAM files online and convert to STEP. Package assembly components in ZIP; missing parts show warnings and properties cover loaded geometry only.
Download the converted file
Select the source and output format, start conversion and download the result. A format with companion files is delivered as a ZIP. Conversion does not recover the original feature tree.
Partial assemblies remain useful
When components are missing, available geometry can still be viewed and downloaded with an incomplete-assembly warning. Dimensions, volume and mass describe loaded geometry only. A file with no usable geometry cannot be displayed.
Source versions and assembly roots
Validated samples establish these workflows, not every CAD version or feature. NX PRT is not a promise of support for other applications using PRT. Package all local references. If more than one root is possible, choose it in the conversion panel. Empty or unreadable geometry is rejected.
Questions about this task
Know the limits.
Which files can I process?
View STEP, IGES, SolidWorks, Siemens NX / UG NX, Inventor, CATIA CATPart/CATProduct, Parasolid X_T, ACIS SAT, JT with readable solids, STL, OBJ, 3MF and static GLB/glTF. ZIP packages retain assembly references. Missing parts show warnings. CATIA CGR/3DXML, X_B, SAB and DWG remain unverified or unavailable.
Are files uploaded?
Yes. Selecting or dropping files uploads and processes them immediately in every tool. Files are processed temporarily on this server. The workspace displays the configured retention time. Delete in the file menu permanently removes your files; closing a view does not.
Do I need an account?
No. Your temporary workspace uses a browser session cookie. There is no account, subscription or permanent file library.
How are properties calculated?
STEP/IGES and converted native CAD use B-Rep geometry; mesh properties are approximate. Incomplete assembly properties cover loaded components only. Mass uses your chosen density.
