Sorry this is actually my first time working with svg (had to edit someone's file) and using inkscape (or illustrator for that matter), all I know what you did was you made 3 rounded squares of different sizes, centered them with different colors, and finally group them into 1 object. I did the same...

Yea this is what I get:


The borders increased, even though you saw that I did not enable those 4 affect options.

If I am doing it wrong please ELI5

I tried to resize while F2 doesnt seem to work. http://i.imgur.com/K95dDrU.png

This is what it looks like separately: http://i.imgur.com/txwZfsx.png

I am editing a svg so I'm not sure how it was made.

I have 2 rounded square borders (of 2 different colors), and one innermost rounded square from a svg, as shown here http://i.imgur.com/TjFQTfu.png. I would like to enlarge the innermost while keeping the WIDTH/THICKNESS of the 2 outer borders. How do I do that using Inkscape?
