I'm trying to insert a surface using a DLL file, but it looks like my OpticStudio is not recognize the file.
My actions were putting the file in C:\ProgramData\Zemax\DLL\Surfaces (where all the other user define functions located) and then search for this file in the lens data editor.
(I followed the instruction from https://my.zemax.com/en-US/Knowledge-Base/kb-article/?ka=KA-01787. Without making any changes)
Looking over the list, I don't see my file.
What could be the reason for that? What is the right way to use user-defined function/ DLL functions?
Thanks a lot!
