You can use tools and commands to quickly export structures, currently you can export CustomMachinery (Fork), [GTM] GregTechCEu Modern, Masterful Machinery, NBT structure format (the front of the structure is the Z-axis, This mod has a wireframe rendering mode that can be changed to a single square border rendering (FULL) by default, and can be changed to a multi-block border rendering mode (OUTLINE)

How to use: After selecting two points, enter the command /StructureCraft CM, GTM, MM and enter the controller id and NBT to export the corresponding format file.
Take GTM as an example

/StructureCraft GTM 'gtceu:greenhouse'
