Users reported that the “Save as 3D PDF” option is missing or fails to export properly. This has been noted especially in SOLIDWORKS 2024 SP2, where the feature was temporarily broken.
Common Symptoms
-
“Save As → PDF” does not show 3D option.
-
Export completes but PDF opens blank.
-
Error: “Could not save file due to internal error.”
Solution Steps
-
Verify you are saving from a part or assembly (3D PDF not supported directly from 2D drawings).
-
Update to SOLIDWORKS 2024 SP3.0 or newer — the issue was patched.
-
Avoid filenames with special characters or overly long paths (known cause of failed 3D exports).
