A tier-1 automotive supplier sends a .EASM file of a bracket to a machining shop. The shop uses the eDrawings Viewer to check which holes need tapping and which need reaming without asking for the native CAM file.

The 3D eDrawings viewer is a standalone software application that allows users to open and interact with 3D CAD models and 2D drawings. Developed by , it is particularly famous for its native support of SOLIDWORKS files, but it serves as a universal hub for various CAD formats.

Download the free 3D eDrawings viewer (available for Windows, Mac, iOS, and Android). Next time a client asks for a "picture," send them the 3D reality instead.

At its core, the 3D eDrawings Viewer is a free application developed by Dassault Systèmes (the creators of SolidWorks). Its primary function is to allow users to view, print, and review native 3D CAD files and their proprietary eDrawings (.eprt, .easm, .edrw) format.

In the modern manufacturing and product design landscape, the ability to share and visualize complex 3D models without exposing native CAD files is paramount. Engineers, contractors, and clients often speak different "technical languages," and file compatibility issues can bring projects to a grinding halt.

While it originated as a companion tool for SOLIDWORKS, the 3D eDrawings Viewer has evolved to support a wide range of CAD formats, making it a versatile "universal viewer" for many engineering organizations.

If you are currently taking screenshots of your CAD models and pasting them into PowerPoint, you are wasting time and risking miscommunication. A static 2D image cannot convey the depth, tolerance, or fit of a 3D object.

Suddenly, you’re trouble-shooting driver issues, explaining what a "file extension" is, or worse—exporting 20 static screenshots that hide all the critical geometry.

The proprietary .EPRT (eDrawings Part) file is a lightweight, self-contained "envelope." It strips away the complex parametric history of a CAD file but retains the exact visual geometry. These files are often 95% smaller than their native counterparts, making them ideal for email attachment.

: Includes tools for dynamic cross-sectioning to see internal details, moving components to understand assembly, and viewing exploded configurations.

You might think, "I’ll just use a 3D PDF." Bad idea. 3D PDFs are clunky, browser support is dying, and they leak performance. The eDrawings format ( .easm for assemblies, .eprt for parts) is engineered for speed. You can pan, zoom, and orbit a 5,000-part assembly with zero lag on a standard laptop.

In the world of product design and engineering, the ability to share complex 3D data across teams—without requiring expensive CAD licenses—is critical. The is the industry-standard tool designed to solve this exact problem, offering a free, lightweight solution for viewing, interrogating, and sharing high-fidelity 3D models.
