This mod allows you to instantly build lines, columns, walls and floors by easily setting the size with your mouse cursor using just one key on your keyboard (default is the right shift key).
"If you are tired of building identical parts for your incredible structures, constantly clicking the mouse button to place each block, this mod will save you from this tedious routine!"

Fourth mode - 3D Openbox (available only starting with version Smart Build Lib 2. 2. 0)
!(https://cdn.modrinth.com/data/cached_images/53904cea9b5887d6bc647925be606b27fe0eaf14_0.webp) !(https://cdn.modrinth.com/data/cached_images/6b6ca19a7231b494f0d4d13538a55f824928b797_0.webp) After that, set the first block, move to the other side and set the second block, after which the selected area will be filled with the same blocks as the first one in exactly the same position.
In addition, when switching to selection mode, the range of interaction with blocks increases to 20. This can be configured in the configuration file.
_Please note that the creation of structures depends on the position of the first and last blocks you click. If you click on the first block and move in a direction where there are no blocks, pay attention to the position of the mouse pointer. If you move the cursor slightly below or slightly to the side, instead of creating a single line, you'll create a wall or floor._
