Hi, I've tried searching for the problem but haven't had any luck, perhaps I don't know the right keywords. If I make an art brush, say two solid rectangles when I apply this to a shape such as a square or star, there is a corner/point that doesn't seem connected, I get a gap/split. I'm guessing it is where the brush has started/ended along the path. These shapes are closed though right? Is there a way to avoid the gap/split? I noticed if I use the pen tool to give the point handles it'll seem connected, however now the shape is not a corner.
I know I can also use the apperance panel and set two strokes aligned along the outside, but this does not seem easy to update sizes, say I had 7 strokes for a rainbow for example each at 5 pt and wanted to update that to 7pt I would have to manually update each one? I also don't think I can use the appearance panel to set up a gradient stroke that flows along the path, such as a square with rounded corners applied, when I tried with the appearance panel it was as if it was masking a gradient beneath it.
I am using CS6, though I'm planning to switch to CC shortly if that offers any new features that would help.
