How to Share a STEP File With Someone Who Doesn't Have SolidWorks

Need to send a STEP file to a client or subcontractor without CAD software? Here's how to make it accessible in 60 seconds, from any browser.

STEP files are the universal standard for exchanging CAD models across the industry. The problem: opening one requires SolidWorks, CATIA, Fusion 360, or a specialized viewer. Your client has none of these.

The real problem with STEP files

When you send a STEP file by email, your recipient gets a file they can't open. They have to download software, install it, then learn how to navigate it. In practice, 60% of the time they call you back asking for a PDF or screenshot — losing most of the 3D information in the process.

• A client approves a part from a flattened 2D photo instead of the actual 3D model
• A subcontractor assembles a part the wrong way without an exploded view
• A sales rep can't show the product on mobile without a desktop PC

The solution: convert your STEP to an interactive 3D link

OmniView 3D converts your STEP file into an interactive viewer accessible from any browser. Your recipient gets a link, clicks it, and rotates the model on their phone. No installation, no account, no training required.

1. 1Upload your STEP file to omniview3d.com (free plan available)
2. 2OmniView converts the file into a 3D viewer in under 60 seconds
3. 3Copy the shareable link and send it by email, Slack, or WhatsApp
4. 4Your recipient opens the model in their browser — no software required

What your recipient sees

The OmniView 3D viewer lets them rotate the model, zoom, activate exploded view to inspect sub-assemblies, and display automatic dimensions — all in a browser tab, no plugins or downloads.

Security and confidentiality

Your CAD files are often confidential. OmniView 3D hosts your models in Europe (AWS eu-west-1), you control who can see each link, and you can delete a model at any time. Sharing can be public or restricted to a private link.
