changing the alignment on a SS4 corridor

How  do you change the alignment on the corridor ?

  • Would also be interested to know if it is possible to change the horizontal alignment a corridor is associated with once it has been created.

    Basically if I've already created a corridor, dropped templates, assigned point controls, etc; then I have multiple proposed alignments, it would be great to be able to just change the alignment association rather than build a new corridor for each one.

    I understand I can edit the horizontal alignment after the corridor is setup but if at 60% I am given a new proposed alignment I'd like to simply change the created corridors horizontal alignment to the new one without having to start over or modifying the existing alignment by hand.
