Do I need Siemens NX to open the files?

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

Can I view assemblies?

Yes. NX parts and assemblies can be inspected with structure preserved where available.

Yes. Convert NX to STEP, glTF, OBJ, STL or FBX once the model looks correct.

NX Viewer中文

Opens .prt directly in the browser — no software to install.

Open and preview Siemens NX parts and assemblies directly in your browser. Inspect models for review and sharing without an NX license.

View NX .prt files in the browser without Siemens NX installed.

Browse part hierarchy and structure of NX assemblies.

Once confirmed, convert NX to STEP, glTF, OBJ, STL or FBX.

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

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

Note that .prt is used by several CAD systems; this viewer targets Siemens NX parts.

For Creo .prt files, use the Creo viewer instead.

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

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