Hi,
We have upgraded OCC version from 7.2 to 7.5 in our code.
After the upgradation we found that, one of the shape is not getting exported in STEP correctly.
I have attached STEP files, one is exported using OCC 7.2 version and other is with OCC 7.5 version and also snap of the imported STEP using both versions.
Are there any changes in STEP Export API or BRepFeat_SplitShape API?
Please help!

Hi,
I haven't heard from you since I posted it.
Any lead?

Hi,
Version 7.5 is much older than version 7.2
We have made many changes to the export process. Perhaps this regression could have appeared in 7.5 or versions in between.
Finding a resolved ticket will take a long time. You can check the working version by saving the original file in breb or xbf format (our internal CAD format). Then import it and export it in the versions(branch) of Cascade that you needed.
I think the problem appeared due to changes in the export process. BRepFeat_SplitShape does not affect to export.
I haven't any ability to find a problem without an original file.
If the current issue reproduces in occt 7.6, you can create a new ticket. But we need an example file or example commands to generate a file to reproduce.
Best regards,
Dmitry.
