Collaborate with Manufacturers Without a CAD License

The Problem: CAD Licenses Keep Getting in the Way

You finish designing a part, and then comes the hard part: getting manufacturing to build it. You need to share your STEP file, add critical tolerances, specify thread details, and highlight key dimensions. But your manufacturer doesn't have a CAD license. They can't open your files. They can't see your annotations. So you end up sending screenshots, PDF printouts, or worse—trying to explain critical details over email. Mistakes happen. Rework costs money. And the back-and-forth drags on for days.

The Solution: Share Annotated STEP Files Directly in Your Browser

OnyxCAD lets you upload STEP files, add professional annotations, and share via a simple link—no CAD software or license required. Here's how it works:

Step 1: Upload your STEP file. Drag and drop your file into OnyxCAD. It works entirely in your browser, so there's nothing to install.

Step 2: Add tolerances, threads, colors, and notes. Use the annotation tools to mark up your design exactly how you need it. Specify GD&T tolerances, thread specifications, color-code critical features, and add text notes for context.

Step 3: Generate a shareable link. One click gives you a URL you can send to anyone—manufacturer, supplier, internal team, or client.

Step 4: They view and collaborate for free. Your recipient opens the link in their browser and sees your fully annotated model. No software, no login required, no license needed on their end.

Why This Matters

When you remove the CAD license barrier, you remove friction from the entire manufacturing handoff. Your manufacturer sees exactly what you intend—no guessing, no misread print, no version confusion. You get faster approvals, fewer errors, and cleaner communication. And because everything lives in the cloud, everyone sees the latest version automatically. It's collaboration that actually works, without software barriers slowing you down.
