The Best Free SolidWorks Viewers for 2026: Open and Inspect CAD Files Without a License
If you work in manufacturing, engineering, or design, you’ve likely encountered the "SolidWorks hurdle." Someone sends you a .SLDPRT or .SLDASM file, but you don't have a $4,000 SolidWorks license to open it.
Whether you're a project manager needing to check a dimension or a machinist viewing a part on the shop floor, you need a SolidWorks viewer free of charge. In this updated 2026 guide, we break down the best official and third-party tools to view CAD files without spending a dime. 1. eDrawings Viewer (The Official Gold Standard)
Produced by Dassault Systèmes (the makers of SolidWorks), eDrawings Viewer remains the most reliable free tool. It is designed specifically to allow non-CAD users to view, print, and review designs. Best For: Most users who need 100% accuracy. Key Features: Supports native SolidWorks formats, DWG, and DXF. Measure Tool: Check dimensions easily. Exploded Views: See how complex assemblies fit together.
Mobile Support: Available on iOS and Android for on-the-go viewing.
The Pro Tip: While there is a "Professional" version, the free version covers 90% of basic viewing and markup needs. 2. Onshape (The Best Cloud-Based Alternative)
Founded by the original creators of SolidWorks, Onshape is a professional-grade CAD platform that runs entirely in your web browser. Best For: Users who don't want to install software. Key Features:
Free Plan: Allows you to import and view SolidWorks files in a browser. No Install: Works on Mac, Linux, and Chromebooks.
Collaboration: Share a link with a teammate to view the model simultaneously.
Note: Your files must be "Public" on the free tier, so avoid this for highly sensitive or proprietary data. 3. Autodesk Viewer (Web-Based Simplicity)
Autodesk might be SolidWorks' biggest rival, but their online viewer is remarkably platform-agnostic. Best For: Quick, one-off viewing sessions. Key Features: Supports over 80 file formats, including SolidWorks.
Live Review: Host a session where others can see your screen as you rotate the model.
Markup Tools: Add comments and callouts directly to the 3D space.
How to use: Simply drag and drop your file into the Autodesk Viewer website. 4. ShareCAD.org (Ultra-Lightweight)
If you are on a slow connection or an old computer and just need to see what a file looks like, ShareCAD is a no-frills solution. Best For: Low-spec hardware.
Pros: Instant upload; no account required for basic viewing.
Cons: Very limited features—no advanced measuring or sectioning. 5. FreeCAD (The Open-Source Powerhouse)
If you want more than just a viewer—perhaps you need to make minor tweaks or export the file to a different format—FreeCAD is the answer. Best For: Power users and makers. Key Features: Completely open-source and free forever.
Can import SolidWorks files (though complex assemblies may occasionally lose some metadata).
Allows for "Step" file conversion, making it a great middleman tool. Comparison Table: Which Free Viewer Should You Choose?

For most professionals, eDrawings Viewer is the "set it and forget it" solution. It ensures that what you see is exactly what the designer intended. However, if you are working across different operating systems (like a MacBook), Onshape or Autodesk Viewer provide the most flexibility without the need for a bulky installation.
Warning: Always ensure you are downloading these tools from official sites to avoid malware. "Free" software on third-party mirrors often comes with unwanted bundled apps.
The primary tool for viewing SolidWorks files for free is eDrawings Viewer, a lightweight solution developed by Dassault Systèmes for users who need to view, print, and review 2D and 3D CAD data without a full SolidWorks license. 1. Core Free Viewer: eDrawings Viewer
eDrawings Viewer is the official free software for design interrogation. It is widely used by students, manufacturers, and collaborators to share high-fidelity 3D data in a compact format. Review 2D & 3D Designs with eDrawings
7) Privacy & file handling note
Browser viewers require uploading files to a third-party service—avoid uploading sensitive IP unless you trust the service’s handling.
Version Compatibility
If you cannot open a file, it is likely a version mismatch. SolidWorks is not backward compatible. If a colleague sends you a file made in SolidWorks 2024, you generally cannot open it with eDrawings 2022. You must download the latest version of the free eDrawings viewer to open newer files.
Step-by-Step: Installing Your Free Update (Troubleshooting)
Users searching for "solidworks viewer free upd" often struggle with installation errors. Here is how to fix the top three issues:
Issue 1: "Update failed – Missing .NET Framework"
- Solution: The 2026 viewer update requires .NET 8.0. Download it from Microsoft before running the SOLIDWORKS updater.
Issue 2: "Old version remains after update"
- Solution: The updater does not overwrite legacy versions automatically. Go to Control Panel > Uninstall a Program. Manually remove eDrawings 2024 or 2025, then run the 2026 installer fresh.
Issue 3: "Cannot open SLDASM files from 2026"
- Solution: You downloaded the wrong build. Ensure you selected "eDrawings 2026 SP0" not "eDrawings 2025." The file icon should be blue (2025 is green).
For eDrawings Viewer (Desktop):
- Go to the official Dassault Systèmes website.
- Navigate to Downloads > Free eDrawings Viewer.
- Version Check: Ensure the build number is
28.1.xxxx(2026 release). - Select your OS (Windows 11/10, macOS Ventura or newer).
- Install. Pro Tip: Uncheck the "Install Browser Plugin" option—it is deprecated in this update.
Ideal for:
- Manufacturing shops – View dimensions, check clearances without buying CAD.
- Sales/engineering reviewers – Redline markups for design changes.
- Students – Open any SW file from class, measure, explode.
- Suppliers – Receive SW files from customers, view without license.
