Hello and welcome.
Your interest in the paths is good, however there is no tool to plot them out.
VC paths are done, with some changes for the extra roads.
LC paths are done, need to be put in but these are buggy.
SA paths are in VC format, these need to be aligned to SA current postion.
Everywhere else has no paths, however there is no tool to do this yet.
3dsmax can create paths in SA format, maybe these can be converted.
Your input is welcome..
Was playing around to get SF moved. It was done rather quickly after I figured out how much they needed to be moved. All get LV and LS done tomorrow, off to sleep now. Here is a pic, done in paint because Im too lazy to open Photoshop right now:

In regards to making new paths, there are multiple ways of doing this. New Paths can be created through Ked, but its quiet time consuming, best bet would be to create new paths through the Path Editor program or Steve M's max script using splines. However there is no point of doing this right now until paths are implemented.
