Grunge brush – dashed, but looks still like a whole stroke

[PierreDaniel]

Hello community

I'm using a fancy grunge brush (like on the left), but I want it to be streaked.
When I select the "dashed line" function in Illustrator, the line now consists of countless small grunge brushes (middle) - but I want it to look more like a long, interrupted line (like on the right, simulated with a dashed line that is superimposed). Is that possible, without workaround of a second line?

Thanks for any hints!

Glad you asked!

Because that allows me to mention knockout groups 🙂 My favourite Illustrator feature.

Apply a second stroke to the path on top of the brush with the Appearance panel.

Make it dashed like the grey one.

Apply opacity = 0% to that stroke.

Set the path as a knockout group.

Ich hab mein Illustrator ist zwar in Englisch belassen ;-),  das Video war aber trotzdem sehr hilfreich!
