Yes, I've already read your guide. Good job. I thought about suggesting the "antline forking" to include in your guide but it's a bit finicky.

You posted this screenshot in wildgoosespeeder's guide and when I made the BEEmod extention of it he suggested I include your idea in my guide. But it turned out too long so I made a guide all about AND gates . So thanks for "inventing" this tipe of antline chaining!

I forgot: in this case there's another AND gate involved (not in the picture) with invisible connections to prevent the gate from showing a 'X' for having multiple connections. Cube button -> first AND gate(invisible connection) -> second AND gate(visible connection) -> piston platform. Getting this whole configuration to work as intended was a pain in the ass, I removed some elements in order to take a less-confusing screenshot.

That's correct, you have to find an arrangement that allows the overlay, usually the editor tries to avoid that and have the other antline visible. I have more logic gates doing it on this map. The screenshot is from this map: http://steamcommunity.com/sharedfiles/filedetails/?id=283148541

So basicly one antline is over another? I didn't know the puzzlemaker lets you do that. I still don't know how it did.

The antline from the cube button goes to a panel. The antline from the AND gate goes to the piston platform. I put it onto the other antline's path. It tends to make an antline along the first one but with some fiddling you can find a position to make it overlay.

How did you make the splitting of the antline (the square before the first AND gate) into two seperate antlines - to the piston platform and to the gate?
