It took a long time to figure out how to make a blueprint.
But what I ended up doing is I took a image (blueprint) from the internet, modified it with Photoshop.
(made the streets black and the rest white)
Then I needed it to be 1:1 scale so I looked at how much pixels the images had and scaled up the image with a program.
But now the image was to large to convert and paste in minecraft so I used another progam or website(don't remember)
to cut the image in 9.
After that I used a program to turn the images into pixelart.
The pixelart is a schematic so I then could use "Amulet editor" to paste them in my world.
Technically you could use worldedit to paste in the schem files but they where so big that it was a bit lagy.
"Amulet editor" works better to paste in large scale schem's.
Finally I used Worldedit to make the moutains.

How did you make this? is this a generator?
