How to Open SolidWorks Files from Higher Versions in Older Versions

Opening higher version SolidWorks files in an older version of SolidWorks can be challenging due to the lack of direct backward compatibility. However, there are a few methods you can try to successfully open these files.

1. Save As Older Version

One common approach is to save the file as an older version. Here's how you can do it:

Open the file in the newer version of SolidWorks. Go to File Save As. Select the desired older version from the dropdown menu (e.g., 2019, 2020). Click Save.

By saving it as an older version, you can ensure compatibility with the older version of SolidWorks.

2. Export to Neutral Format

Another option is to export the file to a neutral format that is compatible with older versions of SolidWorks. Popular formats include STEP (), IGES (.iges/.igs), and STL (.stl).

To export:

Open the file in the newer version of SolidWorks. Go to File Save As. Select the desired neutral format from the dropdown menu. Click Save.

Note that while this method allows you to open the file in older versions, you may lose some specific features and parametric data.

3. Use 3D Interconnect

If you have access to SolidWorks 2017 or later, you can use the 3D Interconnect feature to open certain CAD files from other systems. Although this method doesn't directly address the version issue, it can be useful for working with different file types.

4. Third-Party Conversion Tools

Some third-party software tools and services can convert SolidWorks files between different versions. Before using these tools, make sure to research and choose a reputable service to avoid potential data loss or corruption.

5. Contact SolidWorks Support

If none of the above methods work, consider reaching out to SolidWorks support or your local reseller for assistance. They may have additional tools or strategies for handling this issue.

Important Note

Always make a backup of your original files before attempting to convert or modify them. There is always a risk of data loss or corruption during the process.

Understanding SolidWorks File Compatibility

It's important to understand that SOLIDWORKS has always been backward compatible. The most recent version of SOLIDWORKS can open any previous version SOLIDWORKS file extension. For example, SolidWorks 2018 can open files created in 2017 and older. However, forward compatibility doesn't exist due to the ever-evolving software package.

Every year, SOLIDWORKS enhances their software with new tools or performance enhancements. Once a file gets saved with these new technologies, it becomes locked and can no longer be opened in previous releases. In previous versions of SOLIDWORKS, certain features were missing (e.g., the slot option), which can create issues when opening new files in older versions.

With the enhancement in SOLIDWORKS 2018 SP5, users can now open and view future version SOLIDWORKS files. However, the feature manager tree will be limited to one feature, indicating the file is in a future version format.

Conclusion

In conclusion, when working with SolidWorks files, it's crucial to have access to the appropriate version of the software to ensure full compatibility and functionality. By using the methods mentioned above, you can successfully open and work with files from higher versions in older versions of SolidWorks.
