Hi, Can anyone give me some pointers on how to identify the most appropriate full section front view for such objects, given the top view and the front view? Do I have to be able to visualize them or are there a set of general rules that will lead me to the correct answer? thanks
Just a quick stab at a response for this. Unfortunately a lot of this is visualization but as I stared at your included picture and think about my thought process a couple things occur to me. First, One of the first things I notice is that some of the section view choices have hidden lines where solid lines should be. So a good first step is to imagine how each feature (notch, keyway, hole, part edge, etc) would be represented in the section view. Example, in problem 3 there are what appear to be 2 keyways opposite each other. The section is cut right through the keyways. The appropriate section would then be choice D because the keyway edge on the minor diameter would be directly visible therefore represented by a solid line. Also, the side of the keyway is not part of the actual cut and therefore wouldnt be cross hatched. I'm not going to go through each of those but that is the type of thinking process that is required for tasks like this. I hope this helps in some small way at least.
