Do I need PTC Creo installed?

No. Upload your Creo .prt or .asm file and convert it to STEP online — no Creo license required.

Are assemblies supported?

Yes. Creo parts (.prt) and assemblies (.asm) 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 Creo design.

Keeps solids

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

No Creo license

No PTC Creo needed — upload your .prt or .asm in the browser.

When to use it

When you must share a Creo model with a supplier, client 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 Creo file.

What is preserved

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

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

Creo .prt note

PTC Creo uses .prt for parts and .asm for assemblies.

For Siemens NX .prt files, use the NX converters instead.
