Negative track heights
Posted: 01 Dec 2015, 16:36
I am trying to draw a layout which has portions that go below the baseboard datum, and portions that go above.
That seems like a reasonable thing to do, but RM doesn't seem to allow negative track heights. If you enter a negative number in the elevation popup it gets converted to positive when the keyboard focus moves away; when you use Adjust Height > Edit Selection Start and End Heights again negative numbers are converted to positive ones.
I'm probably approaching this wrong, so... how should I (or RM) handle tracks that go below the baseboard? Adding an offset to everything (if I know my lowest point) would work, but it feels like the kind of thing a computer should handle automatically for me.
