6 u- h* d: |2 W/ @8 K1 sTalking about your explanation, I think that every sentence is understandable except this one: “Line elements is a 2D element, like it just has dimensions in X and Y, and NEVER think about you can measure line elements in Z axis.” My understanding is that even though you measure line elements in specified view direction ( either front view or side view ), it doesn't mean the measured line element is a 2D element. Furthermore, actually it is still a 3D element. When you measure it with an indicator, what will you get? You must get some values in Z axis. 7 ]* H* L4 D/ S8 ~
