How to open a .solidworks part (.sldprt) file
Start with a trusted app that supports this format
- Check the file extension carefully and confirm that the file name really ends with .solidworks part (.sldprt).
- Use software that supports this file type. If one app does not work, try another compatible program for the same platform.
- Update the application if the file was created by a newer version of the software.
- Scan files from unknown sources before opening them, especially documents, archives, scripts, installers, and executable files.
What is a .solidworks part (.sldprt) file?
File extension details and usage information
A .SLDPRT file is a 3D part file created by SolidWorks, a popular CAD (Computer-Aided Design) software application developed by Dassault Systèmes. These files contain the 3D geometric data and features that define a single component or part within a larger assembly. The information stored includes the part's geometry (surfaces, solids, curves), features (holes, extrusions, fillets, chamfers), material properties (density, color, texture), and any associated metadata. SolidWorks uses a parametric modeling approach, meaning that the part's design is defined by parameters and relationships, allowing for easy modification and updates. The .SLDPRT file format is proprietary to SolidWorks, and while other CAD programs may be able to import or export to similar formats, full compatibility and feature preservation are best achieved using SolidWorks itself. These files are essential for creating complex mechanical designs, products, and assemblies in various industries, including manufacturing, engineering, and product design. They are typically used in conjunction with .SLDASM (SolidWorks Assembly) files to create complete product models.

Frequently Asked Questions
Common questions about .solidworks part (.sldprt) files
To open a .solidworks part (.sldprt) file, use software that supports this file format.
- SolidWorks
- eDrawings Viewer
- DraftSight
- Autodesk Inventor (with appropriate plugins)
- SolidView/Lite
Open the file in compatible software and look for options such as Save As, Export, or Convert. If no export option is available, the file may require a specialized converter or the original application that created it.
- Verify that the file extension is correct.
- Install or update compatible software.
- Try another application that supports this format.
- Check whether the file is corrupted, incomplete, or encrypted.
A file extension alone does not guarantee whether a file is safe or unsafe. Only open files from trusted sources, scan unknown files before opening them, and be especially careful with executable, script, archive, and document files.
File safety tips
Use caution with unknown files
Only open files from trusted sources. Before opening a .solidworks part (.sldprt) file, scan it with antivirus software, verify that the file extension is expected, and avoid running unknown executable, installer, macro-enabled document, or script files.
