For all other scenarios (e.g., trying to open a 2025 file in 2020), you must use neutral file formats: How to Open Future Version Files in SOLIDWORKS
: SolidWorks 2024 SP5 can open SolidWorks 2025 files. It cannot open SolidWorks 2026 files. Limitations of this Method
For assemblies, the converter may flatten sub-assemblies into a single level of components if the sub-assembly was saved in a newer version than the converter supports.
Note: FeatureWorks works best on simple, prismatic parts. Complex organic surfaces or highly complex assemblies rarely translate back perfectly. Cloud Alternatives: 3DEXPERIENCE & Collaborative Sharing solidworks future version file converter link
In SOLIDWORKS 2025, you can select File > Save As and choose to save the model as a 2024 or 2023 version.
If you import a STEP or Parasolid file into an older version of SolidWorks and desperately need to edit it, you can use the built-in add-in. Go to Insert > FeatureWorks > Recognize Features .
This only works for consecutive releases (e.g., 2023 SP5 cannot open 2025 files). For all other scenarios (e
The Upgrade Assistant will open each file in both the old and new versions, then generate a detailed comparison report highlighting any potential problems, such as:
Method 1: The Built-In Future Version Interoperability (Service Pack 5)
The most common and reliable solution is to ask the sender to export the file to a neutral, universal CAD format. This strips away the feature history and design intent, leaving behind a "dumb solid" — a piece of geometry that any CAD system (including older SOLIDWORKS versions) can import. Note: FeatureWorks works best on simple, prismatic parts

These converters are often the most practical solution when the "Save as Previous Version" feature is insufficient or when working with non-native file formats.
I will follow the search plan provided in the hints. The first round of searches will cover the general concept, converters, workarounds, and official tools. search results have provided a lot of useful information. I've identified several key topics: the "Save as Previous Version" feature introduced in SOLIDWORKS 2024, the limited forward compatibility (read-only) available in Service Pack 5 of previous versions, and the use of neutral formats and third-party converters as workarounds.
