Import a STEP or STP file directly in your browser — no SolidWorks, no Fusion 360, nothing to install. Share an interactive link with your client in under a minute.

The STEP format (Standard for the Exchange of Product model data, ISO 10303) is the universal exchange standard for mechanical engineering. It contains precise 3D geometry (NURBS, solids) exported from SolidWorks, CATIA, Fusion 360, NX or Creo. It's the format sent by design offices, subcontractors and suppliers. Problem: opening it requires an expensive CAD license — or a specialized viewer. OmniView 3D converts your STEP into an interactive web viewer, directly in the browser.

Drag and drop your file. Conversion is automatic, in the browser.
A private URL is generated in 60 seconds. Share it by email, Slack or WhatsApp.
No account, no installation, no plugin. Works on all devices.
Share a STEP with a client, subcontractor or workshop without them needing SolidWorks. Design reviews become asynchronous.
Present a part or assembly to a prospect on their phone, in a meeting or remotely — no PowerPoint required.
Access 3D spare parts models from a link, on tablet or mobile, without connecting to the internal CAD server.
Upload your STEP file to OmniView 3D. Conversion happens automatically in the browser via WebAssembly (occt-import-js). You get an interactive 3D viewer in 60 seconds, with no need to install SolidWorks, Fusion 360 or any other CAD software.
STEP and STP refer to the same format (ISO 10303). .step and .stp are two file extensions for the same standard. OmniView 3D imports both without distinction.
Yes. OmniView 3D generates a shareable URL. Your recipient clicks the link and views the 3D model in their browser — no account, no installation, no CAD software needed.
OmniView 3D offers a free Starter plan including 3 models and 100 MB storage, no credit card required. The Pro plan (€49/month) unlocks 50 models, exploded view, dimensions and white-label.
SolidWorks, CATIA, Fusion 360, NX (Siemens), Creo (PTC), FreeCAD, OpenSCAD and most professional CAD tools export to STEP. It is the standard exchange format for mechanical engineering.
Yes. The OmniView 3D viewer is optimized for iOS and Android. Your recipient can rotate, zoom and inspect the model from their phone without a dedicated app. AR is available natively on compatible devices.
Yes. OmniView 3D hosts your files on AWS eu-west-1 (Ireland, EU). Storage is encrypted, links are private by default and you can delete a model at any time. No files are used to train AI.
STEP is the reference format for industrial CAD files (precise geometry, NURBS). GLB is the optimized web format (lighter, real-time rendering). For sharing with engineers, STEP direct is ideal. For client presentations or embedding on a website, converting to GLB improves performance.
