请问这句意思?（从on the other hand 到最后)求大神帮助
The sequence of steps should be logical and understandable. Each step might require a different kind of drawing; a close-up, schematic cross sections, a symbol, etc. On the other hand, aiming only at logic may result in a less inspiring set of drawings. By balancing one element against another drawing size and viewpoint, for example – a more dynamic result can be reached.
