Best Tools to Send 3D Files to Clients in 2026 (Without Them Installing Anything)

Email, Google Drive, WeTransfer or a dedicated 3D viewer link? Compare the 6 best tools for sharing STEP, GLB or FBX files with clients: no software required on their end.

You need to send a STEP, GLB or FBX file to a client. The challenge isn't the transfer — it's making sure they can actually open it, understand it, and give you useful feedback. Email, Google Drive, WeTransfer: all transfer the file. None solve the opening problem.

The real problem: opening, not transferring

Your client receives a .step or .iges file. They double-click. 'Cannot open this file type.' They call you back. You send a 2D PDF screenshot. They sign off on a flat image. A dimension is misread. The part comes back non-conformant. This is the default cycle for 80% of B2B teams sharing 3D files. The solution isn't a better file transfer tool — it's a link that opens the 3D model in any browser, without installation.

What to look for when choosing a 3D file sharing tool

• Can the recipient open the file without installing anything?
• Does it support native CAD formats (STEP, IGES, SolidWorks)?
• Is the file private by default, or publicly accessible?
• Can recipients annotate or comment directly in the viewer?
• Where is data hosted? EU (GDPR) or US?
• What is the cost for a team of 3-10 people?

Top 6 tools to send 3D files to clients

1. OmniView 3D — Best for B2B CAD sharing

OmniView 3D converts your STEP, IGES, GLB or FBX into a shareable 3D link in under 60 seconds. Your client receives a URL, clicks it, and sees the model rotating in their browser — no software, no account, no installation on their end. They can rotate, zoom, explore exploded views and dimensions. Formats: STEP, IGES, GLB, GLTF, FBX, OBJ, STL, DAE, AMF, OFF natively; SolidWorks via a STEP export. EU-hosted, GDPR compliant. Free plan: 3 models, no credit card.

• ✓ No software required on the client side
• ✓ Native STEP, IGES formats (SolidWorks, Catia via STEP export)
• ✓ Private by default — secure signed links
• ✓ EU-hosted, GDPR compliant
• ✓ White-label available (Pro plan)
• ✓ iFrame embed for extranets and client portals

2. Google Drive — For non-CAD 3D files

Google Drive supports basic 3D preview for GLB and OBJ files. It does not support STEP, IGES or SolidWorks — these appear as inaccessible file blobs. Good for sharing lightweight design files (Blender, Sketchup) within a Google Workspace team, not for industrial CAD B2B sharing.

3. WeTransfer — For bulk file transfer, not viewing

WeTransfer sends files up to 2 GB free (200 GB Pro) without requiring a recipient account. It's a mailbox, not a viewer. Your client still needs CAD software to open the file. Good for transferring large assemblies when the supplier already has the right tools.

4. Email attachment — Avoid for STEP files

Email is the default for most teams, but it fails for CAD: attachment limits (10-25 MB), antivirus blocking .step and .sldprt extensions, and the client needing CAD software to open the file. The result is always a screenshot and a flat PDF — which causes specification errors.

5. Dropbox — For teams already on Dropbox

Dropbox Business supports folder sharing with links. 3D preview is limited to GLB and OBJ. No STEP support. A good companion to OmniView 3D for centralized file storage, less useful for final client delivery.

6. Sketchfab — For public 3D showcasing

Sketchfab offers high-quality 3D embeds but does not support STEP natively (manual GLB conversion required), models are public by default, and data is US-hosted. Better for creative portfolios and public product galleries than private B2B CAD sharing.

Frequently asked questions

How do I send a STEP file to someone without SolidWorks?

Upload the file to OmniView 3D (free plan). Copy the generated link and send it by email, Slack or Teams. Your recipient opens it in their browser — no software, no account needed on their end. They rotate the model, zoom in on details, and give you precise feedback.

Can I share a 3D model without the recipient creating an account?

Yes, with OmniView 3D. The shareable link works without a recipient account. You create the account to upload; your client just clicks the link.

What is the best free tool to share 3D files?

OmniView 3D offers a free plan with 3 models and no credit card required. It's the only free tool that combines STEP support, private-by-default links, and an interactive 3D viewer that works in any browser without installation.
