What is a SLDPRT file?
The .SLDPRT file extension stands for a SolidWorks Part file. The company Dassault Systèmes developed this file format for SolidWorks, a popular 3D Computer-Aided Design (CAD) software. A .SLDPRT file stores the 3D geometry and feature data of a single mechanical part. Engineers and designers use these files to create virtual models of physical products. Later, they often combine multiple .SLDPRT files into a single .SLDASM assembly file.
How to open SLDPRT files?
You can natively open and edit .SLDPRT files using SolidWorks. If you do not have a CAD license, you can view the 3D models using the free eDrawings Viewer by Dassault Systèmes. Other CAD programs like Autodesk Fusion 360 or FreeCAD can also import .SLDPRT files. However, complex geometry or design history might change during the import process.
Best practices and conversion
Sometimes you receive a .SLDPRT file but cannot open it due to version mismatch or missing software. viewer.online/sldprt analyzes .SLDPRT files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. If you need to share the 3D model with a manufacturer or someone who uses different CAD software, you should convert it. You can convert .SLDPRT files to neutral 3D formats like .STEP, .IGES, or .STL on convert.guru.
Summary
viewer.online/sldprt directly opens and previews .SLDPRT files in the browser, eliminating the need to install heavy CAD software or troubleshoot compatibility issues.
