Simplest way to stack lines and style individually
Hi,
I am making a map and have several trails that follow the same route.
I want to automate stacking these lines together, and be able to style them independantly of each other.
I have taken the following approach, but there is likely a much better idea since I am not an illustartor expert.
I have the main trail drawn in illustrator as a path.
I then use Effect>Path Offset to get the path repilcated.
Then I use Object>Outline Path.
This gives me basically 3 copies which is all I need.
I want to be able to style the 2 black and 1 white lines individually but I don't know how to do this.
Ideally they would adjust together as a manipulate them, but I need to be able to style them independently.
Heres an example:

On the left is the trail path styled with a 1mm stroke.
On the right I have taken the previous outlined steps, and I consider the object to have 2 black and 1white copy of the path I want.
I am hoping someone can steer me in the right direction.
Thanks.
