EDIT : I am only dealing with parts documents not assemblies (drawing views of parts)

Hello,

I’m attempting to replace the view model of a drawing for a part file that has been renamed. I’ve been following a similar approach outlined in the API documentation, but I’m unsure if the issue lies with my instances variable. The ReplaceModelView function isn't working as expected, and there’s no error message, which is why I suspect the problem might be with how I’m handling the instances variable.

Any help or guidance would be greatly appreciated.

Thank you!
