3D Viewer for Automotive Engineering: Share CAD Without a License

View and share automotive parts and assemblies without a CAD license. OmniView 3D supports STEP, IGES, CATIA and NX exports. Shareable link in 60 seconds.

The automotive industry is one of the world's largest consumers of CAD data. CATIA, NX, Creo, and SolidWorks generate millions of parts and assemblies every year. Yet only a fraction of teams hold the licenses to open them. OmniView 3D is the 3D viewer that gives every team — procurement, quality, production, aftersales, commercial — access to these files from their browser, with no software.

The CAD Sharing Problem in Automotive Supply Chains

An OEM works with thousands of Tier 1 and Tier 2 suppliers. Every new part or revision involves CAD data exchange between teams using different software. STEP (ISO 10303) is the neutral reference format, but even STEP requires CAD software to open. OmniView 3D converts any STEP file into a shareable web viewer in 60 seconds — no software on either side.

• Procurement: validate part geometry before order placement — no CAD license needed
• Quality: compare 3D model against the physical part on the shop floor (tablet/mobile)
• Production: access 3D views for assembly and adjustment on the line
• Aftersales: visualize spare parts for field technicians
• Tier 2 suppliers: receive technical data without investing in CAD licenses
• Sales: present vehicle assemblies to the dealer network without dedicated software

Automotive CAD Formats Supported

OmniView 3D opens exports from all major automotive CAD tools: STEP (from CATIA V5/V6, NX, Creo, SolidWorks), IGES (legacy supply chain), STL (prototype 3D printing), FBX and GLB (design visualization, client presentation). Native CATIA, NX, or Creo files are not opened directly — the STEP export from these tools takes under one minute.

What 3D software do automotive engineers use?

Engineers use CATIA, NX, or Creo internally. For cross-team sharing: OmniView 3D (web viewer, shareable link), Kisters 3DViewStation (desktop, widely used in automotive), JT2Go by Siemens (JT format, free). OmniView is the only one generating a shareable link without installation on the recipient's side.

How do I share a car part 3D model with a supplier?

Export the part as STEP from CATIA or NX. Upload to OmniView 3D. Share the link via email or supplier portal. The supplier views the part in interactive 3D in their browser — no CAD software required. Password-controlled access protects sensitive geometry.

Can I view CATIA files without a CATIA license?

Yes — by exporting to STEP from CATIA first. OmniView 3D then renders the model interactively in the browser. For native .CATPart access, see our dedicated CATIA viewer guide.

What format do Tier 1 automotive suppliers use for data exchange?

STEP AP214 and AP242 are the standard formats for automotive data exchange — they preserve geometry, assembly structure, PMI (Product Manufacturing Information), and material data. JT format is also used in Siemens NX environments. OmniView 3D supports STEP natively.

IP Protection in Automotive Data Sharing

Automotive designs are critical IP assets. Sending a native CAD file to a supplier risks unauthorized copying. With OmniView 3D, share a password-protected viewer with an expiry date — the supplier sees the geometry they need for fabrication without ever downloading the source file.
