Arknights Endfield Blueprint System – How to Create, Share, and Copy Base Layouts

The Blueprint system in Arknights: Endfield lets you “snapshot” sections of your AIC base, then instantly re‑place, copy, and share them via codes or community boards. It is essentially a factory save/load feature that massively speeds up building once you have a layout you like.

What Blueprints Are and How They Unlock

Blueprints are saved layouts of AIC facilities (miners, smelters, factories, belts, pylons, etc.) that can be redeployed as a single package.​

• You unlock the Blueprint system by progressing the AIC Plan and story, then enabling the Blueprint feature in the AIC menu.​
• Once unlocked, you can:
  • Save any selection of facilities as a Blueprint.
  • Rename and tag it (e.g., “Cuprium line”, “Explosives plant”).
  • Re‑place, move, or delete the whole design at once.​

Icy‑Veins describes blueprints as “one-button factory deployment” that can drop full production lines in seconds instead of manually rebuilding each piece.

How to Create a Blueprint of Your Base Layout

Creating a Blueprint is a three‑step process.

1. Box‑select the layout:
   • In AIC build mode, drag a selection box around the facilities you want to capture (buildings, belts, pylons, etc.).​
2. Save as Blueprint:
   • Choose “Save Blueprint” for the current selection; this stores a snapshot of all chosen structures and relative positions.​
3. Name and tag it:
   • Edit the Blueprint’s name, tags, icon, and description so you can recognize its purpose quickly (e.g., “Valley IV Cuprium T2 line”).​

Reddit testers call Blueprint “a really nice addition” that removes a lot of factory tedium, as long as you still understand basic ratios and power lines.

How to Copy and Place Your Own Blueprints

Once saved, your Blueprint can be copied and placed anywhere with compatible terrain and power.

• Copy/move in the same region:
  • In the Blueprint menu, pick your design and choose where to place it; the game previews the footprint, then builds it if you have enough resources.​
  • You can also move existing layouts by saving them as a Blueprint, deleting the old one, and placing the Blueprint in a new spot.
• Across regions/Sub‑PACs:
  • As long as required facilities are unlocked there, you can place the same Blueprint near another PAC/Sub‑PAC to clone your factory in that area.​

Keengamer’s release guide highlights this as the main way to replicate successful early factories into later regions without redesigning every line.​

How to Share Blueprints with Other Players

Blueprints can be shared via in‑game codes and external community boards.

• In‑game sharing:
  1. Open the Blueprint’s details and choose Submit for Review; once approved, its status changes from “Under Review” to “Share”.​​
  2. From there you can:
     • Share with Friends directly in‑game, or
     • Generate a share code to give to other players.​
  3. Other players import by opening the Blueprint menu, going to the Share/Import tab, entering the code, and confirming.
• Community boards and tools:
  • Sites like Game8’s AIC Blueprint Sharing Board let players post images plus share codes so others can copy their layouts.​
  • The EndfieldTools community hub hosts simulated factories with “copy in‑game code” buttons and full production stats for more advanced planning.​

Blueprints with many likes or downloads get highlighted, making it easy to find “best practice” layouts for specific products or regions.

When to Use Blueprints vs Manual Building

Guides recommend a hybrid approach: use blueprints to save time, but still learn fundamentals.

• Use Blueprints for:
  • Standardized lines (e.g., ore → bars → parts) that you will repeat in multiple regions.
  • Rapid rebuilds after moving a PAC/Sub‑PAC or redoing a section of your base.
  • Importing community‑tested designs for complex items (e.g., explosives, high‑tier Amethyst chains).
• Build manually when:
  • You are learning ratios, belts, and power; even Reddit blueprint fans warn you still “need to learn the basic fundamentals” or you will copy mistakes.
  • Terrain, power reach, or local resources don’t match the template; you will need to tweak or extend the imported layout.

Used correctly, the Blueprint system lets you turn a single working factory into a reusable, shareable template you can deploy in seconds, while community hubs and codes make copying and iterating on other players’ base layouts straightforward.
