I have developed a standalone C# application to convert a part file to step. It works for 1-2 sample files that I tried. Then I encountered this file for which saved file is same as the input part file. The conversion didn't happen at all.
I tried debugging further and noted the return of the 'SaveAs' api and it was True. I am clueless as to why the conversion doesn't happens.
I also have another app to convert drawings to PDF and a similar thing happens there where it works for a few sample files, but doesn't for 1-2 files.
PFA the code for the same.
