[RKD] Blueprints
A planning table for everything you build in Minecraft: houses and castles from style rules, paths, bridges, rivers and canals, fences and walls, terrain and biomes, whole structures piece by piece, and creatures – planned on the real landscape in 3D, checked as a hologram, then built.
Overview
Beta – test server – Test build for the beta test server. Features and values may still change before the final release; please report bugs.
At its heart is the planning table: it shows the real surroundings as a 3D map – tilt, turn, zoom – with the plan on top in full detail. The bar at the top switches the mode: Buildings & shapes, Paths & water, Terraformer, Structures and Creatures. Settings are on the right, the chain of steps along the bottom (Source → Template → Parameters → Material → Output).
Buildings, paths, walls and terrain tools are rules: more than 100 included rules in many styles, each with its own parameters, plus a rule editor for your own. Whatever you plan appears on site as a hologram of real blocks; it is built from blocks in your inventory (free in creative mode) or piece by piece as a job that can be undone.
The basics from 2.0 are still there: the blueprint with its blueprint pages, the shape planner for domes, roofs and spiral stairs, and the measuring tool for capturing your own builds.
Buildings from rules
Timber-frame house, stone house, log cabin, castle tower, castle and many styles – chalet, Japanese house, Mediterranean villa, Viking longhouse, Moorish house … Every parameter shows up in the inspector and the 3D preview follows instantly. Dormers, skylights, accents, decoration and material slots.
Rule editor
Rules as cards, references as wires, live 3D preview. Built-in rules are saved as your own copy.
Paths & water
Path network with nodes and Bézier handles like in CAD: cobble lane, gravel path, grand avenue, boardwalk … Bridges, steps, plazas at junctions, lanterns and benches. Rivers with meanders and waterfalls, canals with towpath and locks.
Fences & walls
“Enclose” puts a fence or wall around the plan; gates with Shift-click. Wooden and picket fence, hedge, dry-stone wall, iron railing, palisade, castle wall with wall walk and towers, and more.
Terraformer
Level, hills, hollows, terraces, cliffs, lakes, rivers, canals, tunnels, vegetation – with a before/after preview on the map. Runs as a job with progress, pause and undo.
World generation & biomes
Scatter trees, plants, rocks and structures from vanilla and mods over an area as templates; the biome changer turns an area into another biome, optionally including ground and vegetation.
Creatures & traders
Plan any creature from vanilla and mods with traits, stats, equipment and pose, and spawn them singly, scattered or along paths. With Kobase Traders you can set up a trader right at that spot.
Holograms
Buildings, structures, paths, fences and terrain changes appear translucent in the world before building – to walk around, or to build by hand.
Canals (new in 2.1.2)
A constant water level and navigable throughout, tunnels through hills, clearance above the water (trees and overhangs are cleared), old builds in the way are removed. Locks as gates, boat lift or operated locks with controller, canal terminal and a remote with a map. Every surface – bed, walls, coping, towpath, railings, lamps – can be styled freely.
Material list & one button (new in 2.1.2)
Before building, the table shows what is needed and what is missing from your inventory; one main button starts, resumes or applies changes. While a job runs, the table and the display above the hotbar show its progress – if material is missing, it pauses and names the missing blocks.
Reset all (new in 2.1.2)
One button empties a blueprint's whole plan – building with anchor and measuring points, paths, canals, fences, Terraformer, structure assembly and creatures, including holograms and material lists. Click twice to confirm; what's already built stays. “Clear mode” only empties the current mode.
Structures with thumbnails (new in 2.1.2)
The gallery shows every piece as a 3D thumbnail, also on servers far from the world origin; end cities offer every vanilla transition (towers on roofs, the ship). Structures of other mods are recorded in the background only when opened.
Far map (new in 2.1.2)
Zoomed out, the map shows the terrain in a simplified form with biome colours from a cache – even far beyond the loaded chunks, without slowing the server.
Blueprint, shape planner, measuring tool
Blueprint pages with a movable preview, domes/spheres/roofs/spiral stairs, measure your own builds and save them as .nbt in the blueprints/ folder.
Guide
The guide goes through the tools one by one. All pictures are real screenshots from Architect Blueprints 2.1 (game language English).
New in 2.1.2: canals, locks & material list
Draw the canal in the Terraformer (tool Canal) or under Paths & water as a network. The preview gives the water level and whether the canal is navigable throughout; where the ground rises, the canal adds locks. Operated locks fill and drain their chamber and open the gates at the push of a button – at the lock controller, the canal terminal or with the remote. For every job the table shows the material list (available / needed) and the progress.











Planning table & modes
Open the planning table with the blueprint (page Shape planner, right-click). The map shows the real world; the mode bar at the top switches between the tools, and the chain of nodes at the bottom leads step by step to the result.

Buildings & styles
In the Buildings & shapes mode you pick a template from the gallery – a basic shape or a building rule – and adjust it in the inspector. Styles bring their own palettes; material slots replace single blocks with blocks from your inventory.











Rule editor
All buildings, paths, walls and terrain tools are rules. The editor shows how a rule is put together, and you can change it or create new ones.

Paths, rivers & canals
In the Paths & water mode you draw a network of nodes and curves. The type (path, river, canal, fence) and the path rule decide what gets built; bridges, steps and plazas appear automatically.








Fences & walls
Fences and walls use the same network editor, as a closed line around a plot or drawn freely.



Terraformer
The Terraformer shapes terrain: pick a tool, set the area or line with nodes, adjust the parameters. The map shows beforehand what will change; starting it creates a job that works piece by piece and can be undone.









World generation & biomes
Under Vanilla and Mods the building blocks of world generation are ready as templates. The biome changer sets another biome on an area.




Structures
In the Structures mode you assemble structures from their real pieces – by hand at the connection points, or automatically like world generation does.





Creatures & traders
The creature designer plans what spawns where – with a preview of the real creature, placement on the map and ghosts in the world. If Kobase Traders is installed, the Place tab has a Trader section: “Create trader here…” opens the trader editor for the first planned spot.







Holograms & building
As long as you hold the blueprint, the world shows every plan as a hologram of real blocks. Building starts from the table's output step.
