Is there a way to increase the thickness of all lines in a group?

I have some coloring book pages that I'm working on. I have lots of groups that each contain multiple thicknesses of lines. I need to make the ones closer to the front a touch darker than those in the distance. Is there a way to select a group and add .25 thickness to every line in the group? (Or whatever other increment needed.)

Oh, I found this, which I think is what @Ton Frederiks was talking about. The thread is here: https://community.adobe.com/t5/illustrator-discussions/how-to-apply-a-brush-and-keep-stroke-weights/m-p/10976459

And the specific message I'm referring to contains this...
_______

This should work. Make sure to enter the percentage with a decimal point.

//by Ray Craighead
//Resize selected path stroke width(s) by percentage.

function scalePathWidth(){
    var aDoc = app.activeDocument;
    var sel = app.se

There are two simple, about twenty years old scripts by Muchacho (stroke_plus and stroke_minus) that increase or decrease all selected strokes by 0.5 pt.

 

They still work in current versions of Illustrator. Increase/Decrease values can be modified in line 5 and 6.

Okay, first time replying to any thread on here, so sorry if I get the convention a bit wacky. This is the quickest method I have found:

1. Go to Window

2. Click Transform

3. Open the Transform Menu (on my PC it's the "hamburger" symbol)

4. Turn ON "Scale Strokes & Effects"

5. Enlarge the entire group in which you are wanting to increase stokes proportionally by the end percentage you are wanting. (E.g. if I want to increase a stroke by 300%, then enlarge the entire group by 3 times by constraining p

Interesting... Is there some code that I can add that will make it work in groups? Because I have groups within groups. This is always my practice because I have to keep myself organized. 🙂 Some groups inside of other groups have hundreds of lines. This is why I'm looking for this shortcut.

THEN - and this is where the magic happens -

 

6. Go back into the transform menu

7.  Turn OFF "Scale Strokes and Effects"

8.  Reduce the entire group by the same amount that you increased it by. (E.g. divide the width/height by 3 in this example) 

 

It works a charm! The only caveat is that it will also increase effects by the same amount, not just strokes, but perhaps this cuts out a bit of the tediousness.

Thank you! That sounds like a good workaround, too. I appreciate your input!

This might work for scaling many strokes varying in width by a percentage. Use Scale with Scale Strokes & Effects checked and the desired percentage, e.g., 50%. Then reverse the scaling with, e.g., 200% but with Scale with Scale Strokes & Effects unchecked.
