Solid Edge STEP File Import Failure in Solid Edge

Users report that certain STEP files fail to import into Solid Edge, resulting in an empty window with no geometry displayed after the import process.

The issue is caused by invalid STEP file formatting. The customer-provided STEP file lacks the "ENDSEC" keyword to close out the HEADER section, which is required by the STEP file format standard.

Steps to resolve:
1. Verify the integrity of the STEP file by testing it in other CAD applications such as the NIST STEP File Analyzer or other CAD software, e.g. FreeCAD. If the file fails to load correctly in these tools, it confirms that the file itself is invalid.

2. Manually inspect the STEP file format by checking the HEADER section for proper closure with an "ENDSEC" keyword:

3. If the "ENDSEC" keyword is missing, add it manually at the end of the HEADER section:

4. Save the modified STEP file and re-import it into Solid Edge. The geometry should now load correctly:

Notes:

• This issue is not specific to Solid Edge but is due to invalid STEP file creation from the originating system.

• Always ensure STEP files conform to the standard format before submitting a support case. Use external validation tools if necessary.
