In the modern landscape of product design and manufacturing, the ability to share and review complex 3D models is no longer a luxury but a necessity. While native Computer-Aided Design (CAD) software like SolidWorks remains the undisputed king of creation, and PDFs serve as the universal standard for 2D documentation, a distinct category of software—the dedicated SolidWorks viewer—has emerged as the superior solution for a vast range of stakeholders. For project managers, clients, shop floor technicians, and quality assurance teams, a specialized viewer like eDrawings or the SolidWorks Extended Reality (eXR) output is not merely an alternative; it is a fundamentally better tool for accessibility, communication, and design integrity.
The primary advantage of a dedicated SolidWorks viewer lies in its unmatched accessibility and reduced barrier to entry. A full SolidWorks license is a significant financial investment, requires substantial hardware, and demands weeks of training to navigate proficiently. Expecting every supplier, client, or marketing team member to master the native software is impractical and costly. A viewer, conversely, is often free or low-cost, lightweight, and designed with an intuitive, simplified interface. It allows any user to pan, zoom, rotate, and measure a model within minutes of installation. This democratization of 3D data ensures that critical design information is not locked behind a paywall or a steep learning curve, fostering smoother collaboration across the entire product lifecycle.
Furthermore, dedicated viewers excel at preserving design intent while protecting intellectual property (IP). Sharing a native SolidWorks part or assembly file is risky; it contains the complete design tree, feature history, and parametric equations—the very recipe for the product. A viewer, however, typically saves files in a "publi shed" format (such as .easm or .eprt). This format strips away the proprietary construction data, leaving only the final geometry and critical annotations. A supplier can measure a mounting hole’s location and size without reverse-engineering your fillet strategy or extrusion sequence. This provides a perfect balance: stakeholders receive all the information they need for manufacturing or review, yet the core IP remains secure.
Another critical area where viewers prove superior is in communication and markup capability. While native SolidWorks has robust markup tools, they are often buried within menus and require the recipient to have the same software version. Dedicated viewers integrate powerful, yet streamlined, review features like cross-sectioning, dynamic measurement, and 3D commenting. A quality engineer can attach a redline arrow directly to a problematic fillet, add a text note, and save the comment within the lightweight viewer file. This creates a persistent, visual, and unambiguous record of feedback that is far superior to a bulleted list in an email referencing vague coordinates or 2D drawing zones.
Finally, dedicated viewers offer superior performance for non-design tasks. Opening a complex assembly of thousands of components in SolidWorks requires a high-end workstation with a professional GPU and ample RAM. The same assembly, saved in a viewer format, leverages optimized rendering engines that allow for smooth orbit, zoom, and sectioning on a standard laptop or tablet. This portability is transformative for on-site meetings, factory floor walkthroughs, or client presentations. The viewer prioritizes speed and fluidity over editable complexity, which is precisely what a reviewer needs.
In conclusion, while the native SolidWorks environment is the superior tool for creating a model, it is a poor tool for disseminating it. The dedicated SolidWorks viewer—in its various forms—is fundamentally better for the majority of the product team. It lowers the cost and complexity of access, safeguards intellectual property, enhances clarity of communication, and delivers superior performance on standard hardware. By adopting a dedicated viewer as the standard for design review and data sharing, organizations can break down silos, accelerate feedback loops, and protect their most valuable assets, all without sacrificing a single ounce of 3D fidelity. The viewer does not compete with SolidWorks; it completes it. solidworks viewer better
If you are a manufacturing engineer who needs to open 2,000 part assemblies without waiting for an hour, Glovius is the winner.
Why it is "Better":
The Trade-off: It is not free. But for a shop floor PC or a traveling engineer’s laptop, the $199/year license is a fraction of a full SW license and offers a vastly "better" experience.
There is no single "best" viewer because "better" depends on your job role.

A better viewer doesn't just show geometry; it shows intent.
Legacy viewers often displayed a dumb solid—a shape without meaning. Modern viewers are deeply integrated with MBD (Model-Based Definition). When you open a file now, you shouldn't just see a part; you should see the GD&T (Geometric Dimensioning and Tolerancing), the material specifications, and the Bill of Materials (BOM) attached to the file.
This turns the viewer into a communication tool. Instead of a procurement team asking, "What is this part made of?" and waiting 24 hours for an engineer to reply, they click the part in the viewer and see "Stainless Steel 316" instantly. The viewer has become the single source of truth.
The default viewer is notoriously slow when you try to measure geometry. You click a face, wait 3 seconds, then click an edge, wait another 3 seconds. If you are a machinist, fabricator, or purchasing agent trying to verify dimensions quickly, this latency kills productivity.
