Has anyone knowledge on this Pattern Brush issue?
I want to make a line, which narrows down all the way from start to end. So I have made this form (see image) into a pattern brush. I have played with the pattern brush options as much as possible and have applied that pattern brush on a path I have made with the Pen tool, yet ending up invariably with a result something other than what was desired.
I'm using Illustrator CS5.
If you want a "pattern" that goes all the way from the start to the end of a path you don't need a pattern brush you need an art brush. Just select "Art Brush" when creating your brush:
In this case though you'd be better off using a width profile. There is a default width profile exactly as your example:
You can also use the Width tool (shift+W) to adjust the width manually of your stroke:
I think the problem is because the shape you have used for the brush is longer than the little diagonal lines you are drawing. So Illustrator is trying to cram them in between the corner anchors, but at the same scale.
One solution is to reduce the scale of the brush.
Perhaps this isn't what you want at all, I may have misread your quesiton. Another option is to create an Art brush.
Another option that might work is to choose the triangle profile for a regular stroke.
Create a Scatter Brush.
Leave the Rotation Relevive to: Page (this will not rotate the brush).
Play with the Spacing slider.
