Hi,I have done a horizontal and vertical alignment for a 10km road. How can I amend the horizontal alignment without loosing the entire vertical alignment. As soon as I drop complex status on the Horizontal alignment, my Vertical alignment disappears
alternatively, you can create a copy of the horizontal alignment you want to edit: either dgn or use copy tool or create "0" offset, copy vertical to it (it will be sort of buffer to store your vertical while you're editing horizontal), drop your horizontal to make necessary edits, create new complex and copy vertical back to it. hope it makes sense.
