I'm curious as to whether there is any "consensus" in how to handle north arrows when north is shown other than "up" on a plan sheet. For example for a long rectangular structure, it is often more convenient to draw the structure with the north arrow shown either to the right or to the left - is there a preferred direction? On some projects, the structure is skewed up to 45 degrees rather than orthogonal to north - how do you handle showing "north" for such structures? Occasionally I have seen drawings with the north arrow shown "down" on a plan sheet - what basis would there be to show north down? (It seems contrary to intuition since most maps are drawn with north "up".) Also, has anyone encountered problems on projects where different sheets for the same structure show north oriented differently? (e.g., mechanical sheets with north to left and structural sheets with north to right - problems such as mechanical or structural elements field located in the wrong place due to confusion in direction.)
