As you'll see from the attached I have a file with a double lined stroke. I'd like to "break it" (where I've placed a red square) to create space for an object. How do I do that?
Also, I'd like to experiment with playing with the space between the double line in the stroke. To do this, I thought you needed to go into stroke styles and create a new "stripe" stroke style and play with the space between the two lines with the slider. However, when I do that, I lose the width of my existing stroke and it becomes thinner on both lines. Is there a way to avoid that?
Other options for making the gap would be to use the scissor tool, or to draw the shape with the pen tool, leaving the gap.
Stripe style strokes are built using a percentage of the total stroke weight for each element. You don't set an absolute weight in the style definition. To have a wider gap with the same apparent line widths you need to apply a larger value to the stroke weight.
