Do I need Autodesk Inventor installed?

No. Upload your .ipt or .iam file and convert it to STEP online — no Inventor license required.

Are assemblies supported?

Yes. Inventor parts (.ipt) and assemblies (.iam) can be converted to STEP with structure preserved.

Is the STEP editable in other CAD?

Yes. STEP provides precise B-rep solids most CAD systems can import and edit, though the feature history is not transferred.

Universal exchange

STEP is accepted by virtually every CAD system, so partners can open your Inventor design.

Keeps solids

STEP preserves precise B-rep solids and assembly structure for engineering reuse.

No Inventor license

No Autodesk Inventor needed — upload your .ipt or .iam in the browser.

When to use it

When you must share an Inventor model with a supplier or partner on a different CAD system, STEP is the safest neutral handoff.

For long-term archiving and procurement, STEP is more durable than a version-locked native Inventor file.

What is preserved

STEP carries solid geometry and assembly structure, but not the Inventor feature tree or parametric history.

Recipients get editable B-rep geometry, not your design intent timeline.

Parts and assemblies

Inventor uses .ipt for parts and .iam for assemblies.

Both can be converted to STEP for downstream use.
