the DrawingView object has no method "getcenterpoint()".
To transform the circle centeter points in the view just use the ViewToSheet() method.
To get the circles count just use the Count property of the objcircles variable.
An other way to get all centermarks of the circles in the view is to call "RetrieveCenterLinesCenterMarks()".
see you fond the solution.
Since RetrieveCenterLinesCenterMarks() does not return a value the assignment to centermarks incorrect.
centermarks =view.RetrieveCenterLinesCenterMarks(True, "ANSI", False, True, False, True, False, False, True, False, False, False, True, True, 0, 0, 0, 0)
Pls add the next time your code the the "insert code" to your message. It is then more readable
