Let's say I have object A with stroke thickness x, and object B with stroke thickness x as well. I group them to make a single object. Now I want to change the border thickness of this object, to make it thicker. But with the inner stroke thickness unchanged. Is there anyway to do it?
The only way I can think of is to copy the object and increase the thickness of all strokes on the copy and place it precisely behind the original. Although it seems to work, it doesn't feel as though it is the correct way.
