Blueprints in gimp

is there a better, and faster way to perfectly split blueprints in gimp using guides and guilotines?, i can do it perfectly it just takes ages:yes:, oh, and ive tried the split plugin and it didn’t work

I’m used to just use rectangle select tool: Select the area, Copy it to clipboard (Ctrl-C) and Edit --> Paste as new image. I think it is the fastest way.

The rectangle select tool has some useful options: selecting squared area, which is good to get the dimensions right from the beginning, and expanding from center which helps with symmetry. And of course the guides are useful if the pictures are some way lined up. Hope you have remarked, that you can drag the guides with rectangle dragging tool, so you don’t need to count the pixels.
