Parakeet brick

Hi!

I am trying to make a protruding brick script. It seems you need to use a parakeet. Has anyone done any experiments? I wish I could see this tutorials clearly. Let me know if there is any helpful page/your study 04- Parametric Brick

Wall thank you in advance! (pics are samples, does not need to be this shape, brick patterns that parakeet has is sufficient, I just dont know how to make it solid void like these) when I apply this pattern for example, there is no positive and negative (all flat extrusion)
