Proof-read Code (1100 lines, empty lines included) C#

Hi all,


For my company I have created a custom batch-application to create STEP- and PDF files for an assembly and all it's (sub)occurences. This application works most of the times, but not all, and I can't my head around why it isn't. It would mean a lot to me if anyone would like to proof-read what i've created, and maybe detect what could go wrong.


I will provide more details and the code by PM to anyone who would like to help.


Thanks a lot in advance!
