Check if drawing has unsaved user edits

[pball]

I have a batch function that processes open drawings and it closes each drawing it processes. I'd like to check if a drawing has unsaved user edits before closing it. However checking if the status of the file is dirty isn't granular enough of a check. I noticed if you modify a part and then open its drawing, the drawing is dirty because the part changed. I'd like to ignore that situation. I only want to know when a user has edited a drawing. Inventor knows the difference, but I'm not sure if the API can access that info.

Part updated but no changes made to drawing

Drawing edited by user

Try this:

.ActiveDocument.RequiresUpdate

.ActiveDocument.RequiresUpdate

Unfortunately in my quick test .RequiresUpdate returned false for edits make to the drawing and when the model was edited and the drawing opened afterwards. So I'm not sure what updates that property is looking for.
