Overview
What is an EPRT file? An EPRT file is a 3D part exported using Dassault Systèmes eDrawings Publisher, a plug-in used with CAD programs like SolidWorks, AutoCAD, and CATIA. It contains 3D information about a single mechanical component, such as a bolt, gear, bracket, or housing, saved in the eDrawings 3D Part (EPRT) format, a compressed, view-only format.
More Information EPRT file open in Dassault Systemes SolidWorks eDrawings Viewer EPRT files are part of the eDrawings file family, along with .EDRW (2D drawings) and .EASM (3D assemblies). These formats are designed to simplify the sharing and reviewing of CAD data, especially with stakeholders who don't have access to expensive CAD tools. Users receiving EPRT files can use the free eDrawings Viewer (also known as "eDrawings") to view the 3D part, inspect its properties, present it, and print it. The utility is available for Windows, macOS, iOS, and Android.
