While working in Creo, I see that the “view change” window opens every time in the assembly parts we open in the Windchill system, which I share as a screenshot below. Although I have corrected the errors in the system, this screen appears every time I open the assembly file in Creo. Actually, I found the solution to the problem, but I want to know what the root cause of the error is. In which error situation this screen appears. Can anyone write if they have information about this subject?
