Solidworks Prompt to save part even though haven’t made any modifications

When closing the part in Solidworks, it prompts me to save even though I haven’t made any modifications. I simply opened the part and tried to close it

I’ve seen this for various reasons.
Are you working on the same computer as when you originally saved the file?

I don’t have a Swx2025 install right now, but I can try to do that this weekend so I can open your file.

Possibilities

  • A linked equation file
  • Changes to your system options (e.g., changing the default scene or background, or changing whether or not the tesselation data is saved with the file)
  • Changes to the “history length” setting of your feature tree, so when you open the file it may be stripping out existing history
  • Part previously used in an assembly, and saved with a different configuration active than is active in the part file.
  • File generated via pack-and-go
  • Orphan appearances. Sometimes appearances and their associations with bodies are off, so deleting all display states can resolve this. Rolling the tree back to the top, doing ctrl+Q, and rolling it forward can also repair situations where split or mirror body features have confused the solidworks reference tracking.
  • An imported stp file, where the source file has fragilities
