You've spent hours designing a product, a piece of jewelry, an architectural element, or a custom part. The model looks great in your CAD software. Now you need your client to see it, approve it, and give you feedback.
This is where the friction starts. Your client doesn't have Blender. They don't have Fusion 360. They don't know what an STL file is. If you email the file, their computer won't know how to open it. If you send screenshots, they can't see the back, the bottom, or the fine details. If you record a video walkthrough, it takes time to produce and still doesn't let them explore on their own.
The solution is absurdly simple: send them a link. They click it. They see the 3D model in their browser. They rotate it, zoom in, examine every angle. No downloads, no instructions, no "please install this software" emails.
The freelancer's sharing problem
If you're a product designer, architect, jeweler, engineer, or 3D print service provider, you've experienced this exact scenario:
- You email an STL or OBJ file. The client replies: "I can't open this file."
- You suggest they download a free viewer. The client replies: "I don't want to install anything on my work computer."
- You send screenshots from six angles. The client replies: "Can I see it from underneath?"
- You record a screen video rotating the model. The client replies: "Can you pause at 0:23 and zoom in on the hinge?"
- You share via Sketchfab. The client replies: "It's asking me to create an account."
Every one of these approaches adds friction. And friction means slower approvals, more back-and-forth, and frustrated clients who feel like the process should be simpler.
The link solution
Here's the workflow that eliminates all of that friction:
- Open geometryviewer.com in your browser
- Drop your 3D file onto the page — STL, OBJ, GLTF, GLB, or 3MF
- Apply a material preset if desired — chrome, wood, carbon fiber, matte plastic, etc.
- Click "Share" — a unique URL is generated
- Send the link to your client via email, Slack, WhatsApp, iMessage, or any other channel
Your client clicks the link. The model loads in their browser — phone, tablet, laptop, or desktop. They can rotate, zoom, and examine it from every angle. On phones, they can even place it in their room using AR.
No app download. No account creation. No file transfer. No compatibility issues. It just works.
Why this is better than alternatives
vs. Email attachments
Email attachments have size limits (typically 10-25MB). Many STL files exceed this, especially for detailed models. Even if the file fits, the client's computer likely can't open it without installing software. And corporate email systems sometimes block unusual file types.
A link has no size limit, works on any device, and doesn't trigger email security filters.
vs. Screenshots
Screenshots are flat. They show one angle, one perspective. The client can't explore the model, check dimensions intuitively, or examine areas you didn't think to photograph. You end up going back and forth: "Can you show me the other side?" "Can you zoom into the joint?" "What does the bottom look like?"
An interactive 3D view lets the client explore everything at their own pace, on their own terms.
vs. Video walkthroughs
Videos are better than screenshots but still limited. The client sees what you chose to show, at the speed you chose to show it. They can't pause on a specific angle and zoom in. They can't rotate to see an area you didn't include in the walkthrough. And producing a good video walkthrough takes time.
vs. Sketchfab
Sketchfab is a great platform with a large community. But for client sharing, it has friction:
- Account required — you need a Sketchfab account to upload. Your client doesn't need one to view, but the platform's UI is oriented around accounts and social features that distract from simple file viewing.
- Watermarks on free tier — free Sketchfab embeds include a Sketchfab watermark and branding. This looks unprofessional when sharing with a paying client.
- Upload limits — free tier has file size and model count limits.
- Public by default — free Sketchfab models are public. Making a model private requires a paid plan. Not ideal for confidential client work.
GeometryViewer requires no account, has no watermarks, and doesn't make your models public.
vs. Google Drive / Dropbox
Cloud storage services are good for file transfer, but they don't preview 3D files. If you share an STL file via Google Drive, the client sees a download button, not a 3D viewer. They're back to the "I can't open this" problem.
Who this works for
Product designers
Share product prototypes with clients for approval before manufacturing. Apply material presets (brushed metal, matte plastic, wood) to show what the final product might look like. The client sees an interactive 3D preview instead of flat renders.
Architects
Share building models, facade details, or structural elements. Clients can orbit around the model, zoom into specific areas, and get a spatial understanding that flat plans can't provide. AR placement lets them see the model at scale in their environment.
Jewelers
Share ring, pendant, or bracelet designs with customers before casting. Apply gold, silver, or rose gold material presets. The customer sees an interactive 3D preview on their phone — much more compelling than a flat CAD screenshot.
3D print services
When a customer submits a file for printing, share back a preview link showing the model with the selected material and layer height simulation. The customer can confirm it looks right before you start printing.
Engineers and manufacturers
Share custom parts, tooling designs, or fixture models with clients for dimensional review. The interactive 3D view gives clients a much better sense of the part than 2D drawings.
AR for real-world context
When your client opens the shared link on their phone, they can tap "View in AR" to place the model in their physical environment. This adds enormous value for:
- Size verification — "will this product fit on my shelf?"
- Scale understanding — "how big is this part, actually?"
- Spatial planning — "where will this architectural element go?"
- Presentation — showing stakeholders a model sitting on the conference room table
AR requires no app download. It works natively in Safari on iPhone/iPad and in Chrome on most Android devices.
