tbh, I don't know what the exclusion or induction method are but if you really want to do well on TFE you need to be able to visualize the entire piece as a whole. Once you can mentally envision the entire structure the answer will be blatantly obvious... for me that meant that I wrote nothing down on paper and I didn't count any lines for the TFE section. With practice you're going to be good at realizing what information is important.
Truly mentally comprehending the dashed and solid lines will be your quickest way to the answer but don't forget to capitalize on the the basic information also provided.
For instance, if you are given the front view and top view... then you automatically know how tall and wide the end view can be... if the end view is taller than the front view then it is not the correct structure and if the end view is wider than the height of the top view then that is also not the correct structure.
Also, you can use this information many different ways. If you need to determine the front view then you'll realize it can't be taller than the height of the side view.
If you need to determine the top view then it can't be taller than the width of the side view.
The real key to success is being proficient with understanding the dashed and solid lines, but the height tricks can sometimes help eliminate a few wrong answers quickly.
