Works Palletizing Different Layers

Hello, guys,

I’m using works for palletizing simulation because it’s made easy, but I can’t seem to find a way of palletizing the items with a specified pattern, do I need to create a different NeedPattern for every layer? I’ve attached a picture with the layout I want to accomplish. The next layer must be the same but rotated 180 degrees. I do something wrong probably, can someone give me an example or something.

Thank you in advance and cheers!
