1) I basically agree. One question and one note:
- How do we define a 90° angle (which is a realistic case) as a ratio? Mathematically, it would be infinite.
- We still have to define that the relation of "fromNetElement" and "toNetElement" is seen in an anti-clockwise direction, as it would have been for the angle.
2) I have seen ratios in Swiss schematic plans both for switches and crossings. So I think using them makes sense from a business perspective.
