Blueprint Tools is a Factorio mod adding various blueprint manipulation tools to the game.
When holding a configured blueprint, an upgrade planner, or a deconstruction planner, use Shift + B or press the GUI button to open the configuration window for that item. This is especially useful for upgrade and deconstruction planners, allowing you to quickly grab a planner, configure it how you need, use it a few times, then destroy it with ease.
Press Shift + C or press the button to swap a blueprint's circuit wire colors.
Press Shift + T or press the button to open the Set tiles GUI. This function will place tiles under the entities in your blueprint, with an option to fill gaps and add margins around each entity or the entire blueprint.
Press Shift + G or press the button to quickly set a relative grid on the currently held blueprint. The grid will be set to the size of the blueprint. For custom grids, use the Quick configuration hotkey and do it through the GUI.
Press Shift + Up/Down/Left/Right to adjust the grid position relative to blueprint entitites. Ideal for aligning tileable defenses and rails.
Press Control + Shift + Up/Down/Left/Right (for individual blueprints) to adjust the absolute grid position offsets. Blueprint size is taken into account when setting the offsets to avoid having excessivly high offset values. Excellent option when working on city block-style bases.
Separate controls are also available to perform the same action on all blueprints in a blueprint book. Controls for this operation are not set by default in order to avoid accidents (see the Nudge absolute grid up/down/left/right (book) controls in settings). When adjusting all blueprints in a book, currently selected blueprint must have absolute grid position enabled.
