Before we discuss the solution, we must understand the architecture. Unlike AutoCAD (which saves downwards via _SAVEAS ), SolidWorks does save backwards. A file saved in SolidWorks 2025 cannot be opened by SolidWorks 2024.
| Method | How It Works | Best For | |--------|--------------|-----------| | | Exports the exact solid geometry without history. | Sharing precise solid models when feature tree isn't critical. | | STEP/IGES Export | Industry-standard neutral formats. | Interoperability with other CAD systems and older SOLIDWORKS versions. | solidworks future version file converter link
Starting with , users can natively save files back to the previous two releases. If you have the newer version of the software, this is the most reliable way to convert files for others. Before we discuss the solution, we must understand
If you are using SOLIDWORKS 2024 or later, you can export files to older versions while maintaining "deep" feature history: The Process File > Save As | Method | How It Works | Best
