Blueprints are items that contain building layouts. Blueprints are used to 'copy & paste' parts of a factory. Built areas can be selected for inclusion in a blueprint. When a blueprint is placed, a ghost of the layout appears on the ground. This can be used as a guide for manually placing factory pieces, or, more commonly, handed over to construction robots for automated completion.

Blueprints can be stored in a blueprint book or blueprint library to prevent them occupying inventory space or for organization or sharing purposes.

Blank blueprints can be crafted by clicking the ( Blueprint button.png ) button in the shortcut bar. The blank blueprint can now be used to 'copy' a set of buildings. For example, copying this small gun turret defense setup:


Create a blueprint

To create a blueprint select the blueprint item out of the toolbar or the inventory. With the blueprint icon shown next to the mouse cursor, click and hold the left mouse button and drag a box as large as needed (which can be cancelled by pressing Q).

All player-placed entities which will be included in the blueprint will be highlighted with a green square. Once everything you intend to 'copy' is inside the drag box, release the mouse button and the 'Blueprint icon setup' menu will open.


Blueprint icon setup

On the top left of the "Setup new blueprint" menu there are four icon slots. These are displayed on the blueprint's icon and can be used to quickly identify a blueprint. When creating a new blueprint, the game automatically selects some of the icons representing the entities in the blueprint.

These default icons can be changed by simply clicking on the icons to choose the desired ones.

On the left the 'Total' number of components included in the blueprint is shown.

The green "Create blueprint" button creates the blueprint. Additionally, blueprint creation can be cancelled by clicking the X in the top right corner. Canceling the blueprint does not consume the blueprint item. The created blueprint will replace the empty blueprint in the player's cursor.


Placing the blueprint

To use/place the created blueprint select it from the tool belt or inventory. The process of placing a blueprint is very similar to that of using copy and paste functionality.

When you select a blueprint, the whole building setup of the blueprint will be shown at your mouse cursor. In this case the Blueprint was renamed to "Example blueprint".

It is possible to place the blueprint rotated; this is done by using the r key.

Placing a blueprint creates ghost entities. If these are within the green (or orange) 110×110 tiles area of a roboport, or within range of a personal roboport installed in modular armor or spidertron, construction robots may be able to build them using available materials.


After the blueprint gets placed somewhere, the buildings are placed as ghost buildings. Construction robots will now start to pick up the needed items from the construction network/the player inventory (if using a personal roboport) and place them at the ghost buildings.

The required items need to be in the network in an active provider chest, a passive provider chest, a buffer chest or a storage chest.


Blueprints can be placed from map view as long as the area has been explored.

Viewing and clearing a blueprint

Right clicking on a blueprint allows you to view, edit and clear it. By clearing it, it will become blank so it can be set again.

Importing/Exporting blueprints

It is possible to export blueprints as a text string and import said text string to create a new blueprint. This makes sharing blueprints between players very easy.
Clicking the Export to string button ( ExportToString.png ) in the top right of the blueprint edit window will pop up a window containing the Blueprint string. This string can be copied to the operating system clipboard, from where it could be saved to a text file or uploaded to a website.

To import a blueprint, the player can click the Import string icon on the shortcut bar ( ImportString.png ). A dialogue box will appear into which the string can be pasted. This will result in a blueprint appearing on the hand with the same setup as the one that was exported.

The text string itself is a base64 encoded, compressed JSON string which contains all the information of the blueprint. It is therefore possible to decode/decompress the text string, change attributes of the blueprint in the JSON text and finally re-encode/compress it back to the known text string format. This basically allows blueprint editing outside of the game itself.

A complete explanation of the blueprint JSON can be found on the blueprint string format page.

Additional information

  • Once a blueprint is created, it can be used an unlimited amount of times.
  • To place a blueprint that is blocked by existing buildings, you can hold Shift to place the objects that aren't blocked.
  • The above trick will also mark rocks and trees for deconstruction.
  • Buildings marked for destruction will not block placing a blueprint. The blueprinted building cannot be placed if there are any buildings in the way. This can cause an item outside the construction zone to block construction of a 2×2 building on the edge of the zone.
  • The maximum of size a blueprint is 10k by 10k tiles.
