Do I need PTC Creo to open the files?

No. The viewer runs in your browser — upload your Creo .prt or .asm and preview, no Creo license required.

Can I view assemblies?

Yes. Creo parts (.prt) and assemblies (.asm) can be inspected with structure preserved where available.

Yes. Convert Creo to STEP, glTF or STL once the model looks correct.

Creo Viewer中文

Open and preview PTC Creo parts and assemblies directly in your browser. Inspect models for review and sharing without a Creo license.

View Creo .prt / .asm files in the browser without PTC Creo installed.

When a partner sends a Creo file but you have no seat, the online viewer lets you inspect it instantly.

For pre-sales, procurement and project teams, viewing Creo online avoids a heavy license.

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

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

Viewing confirms the source Creo model; conversion produces a deliverable.

For cross-CAD exchange, convert Creo to STEP after reviewing.
