So I am using the "event counting" strategy for Top/Front/End section of PAT (cause I can not even come close to imagining any of these problems in 3D). I have a question though regarding this section. How do you deal with circles in event counting? I know the basic rules (count each angle change, straight line is visible and dashed lines are invisible). However in Crack PAT there are so many questions that they have circles in them. Dose anyone have any idea how to do count them?
