I'm working on a map of National Park "Loonse en Drunense Duinen" in The Netherlands. Here's a little snapshot of where I'm at right now.

The brown line with 'ribbon' is the park boundary and I'm having a bit of a hard time making that mesh with the rest of the information. I really want that ribbon effect, but it seems bl**dy difficult for Illustrator to do that with a complex polygon. I've now used an Offset Path effect on a 2nd stroke at 40% opacity, but it's not really working in all cases. Take the spike in the center of the image for example. Anybody have a suggestion on how to deal with that?

 

Using different styles/colors for different types of routes. Anything blue is cycling, green is hiking and purble is horseback riding. When routes overlap I've tweaked them to be parallel.

Hans, I don't know how you would do this in Illy, but in FreeHand I create an expand stroke first so that there's a new path at the outer edge of the ribbon I want to create. Sometimes I have to edit this new path to delete spikes. Then I clone the original line (i.e., the other edge of the ribbon) and join it with the new path to create a closed path without a stroke. Then I add a fill with transparency. One advantage to this method is that the ribbon "fills" all the nooks and crannies of the original line. And....no spikes! B)

Hans,

 

I had the same issue with the many boundaries on my Koke'e State Park map (http://mapbliss.com/...eeTrailMap.html).

 

If I recall correctly, the solution to getting a band or ribbon that exactly matches the parent stroke and fills all the spaces is to offset the path, then increase its stroke until it blends with the original line, then convert to outline before filling.

 

That my be similar to what Charles is describing, not sure.

 

I'll check the notes for my AI doc to see if I wrote down the exact workflow. I know it took me a while to figure out.

I do this all the time, and I may go about it the wrong/long way but it has always work.

There are two ways depending if you path is closed or open.

 

If it is closed:

Duplicate the original (select line ctrl+c & ctrl+f) then I turn one of the duplicated lines off or lock.

 

then Object--Path--Offset Path.  Positive value put the offset path on the outside and negative on the inside.  Select the original and offset path and make them a compound path (ctrl+8).  Then I just fill the compound path and give the outside line no fill.  Go back and turn on your original line and make sure it is above your compound path in the layers.

 

If it is open:

Duplicate the original, then turn one line off or lock.

 

Object--Path--Offset Path.  It will offset on both sides of your original or form a rectangle.  Then I use the scissor to cut where my original line (middle one) and my offset line intersect on both sides of the path.  I delete whatever side I don't want, and join one side of the offset with the original path.  I give it a fill and no value the stroke, and then turn my duplicated line back on and make sure it is on top.

Maybe I'm missing something, but have you tried to simply align the stroke to the outside of the path instead of the center? Then you wouldn't have to mess with offsetting duplicate paths, and trying to refill the gaps. That's what I've always done and it has worked out well for me.

Tried that and it works fine on simple polygons. This one is far from simple, the option is greyed out :rolleyes:

 

Will try the other suggestions, hopefully later today. Thanks for now though, appreciate it.
