Create: Precision Engineering

Create: Precision Engineering is a Minecraft 1.21.1 NeoForge addon that lets you build functional miniature Create factories inside a single block.

A Precision Engineering Space contains a 7×7×7 internal building area with up to 343 micro-cells. The machines inside are real Minecraft and Create blocks running in a hidden backend — not decorative models or simulated recipes.

Build smaller. Engineer smarter.

Requirements

Required:

• Minecraft Java Edition 1.21.1
• NeoForge 21.1.228 or newer
• Create 6.0.10
  Supported: >= 6.0.10 and < 6.1.0
• Sable 2.0.3 or newer
  Supported: >= 2.0.3 and < 3.0.0

Optional compatibility:

• Create Aeronautics / Simulated 1.3.x

Sable is required because Precision Engineering uses its sub-level and moving-structure systems.

Sable Companion is bundled inside the mod JAR, so it does not need to be installed separately.

Precision Spaces

Each Precision Engineering Space contains a functional 7×7×7 miniature factory area.

You can use it for things such as:

• Create processing machines
• Compact production lines
• Gearboxes and transmissions
• Item and fluid systems
• Redstone controls
• Small kinetic networks
• Reusable factory modules

The goal is to save space without removing Create's engineering mechanics.

Engineering Mode

Use the Engineering Tool on a Precision Space to enter Engineering Mode.

You can directly:

• Place blocks
• Break blocks
• Interact with machines
• Inspect Block Entities
• Build Create belts and machinery
• Use Engineer's Goggles

Your actual player remains outside while you control a virtual camera inside the miniature factory.

Create Kinetics

Precision Engineering works with Create's normal rotational system.

It supports:

• RPM
• Rotation direction
• Stress capacity
• Stress impact
• Imported power
• Internal generation
• Exported power
• Bidirectional kinetic transfer
• Multiple kinetic ports

Machines inside a Precision Space still follow normal Create stress and speed rules.

Optional Internal Generator Scaling

Servers can optionally reduce the Stress Unit capacity produced by generators built inside Precision Spaces.

Default:

[kinetics]
nativeMicroSourceMultiplier = 1.0

1.0 keeps normal Create behavior.

Suggested balance setting:

nativeMicroSourceMultiplier = 0.125

This gives internal generators 12.5% of their normal SU capacity.

The actual micro-grid scale is 1:7, so an exact linear setting would be approximately:

nativeMicroSourceMultiplier = 0.142857

Only power generated inside the Precision Space is reduced.

Power imported from outside remains at 100% capacity, even if it passes through one or more Precision Spaces.

The multiplier does not change:

• RPM
• Rotation direction
• Gear ratios
• Machine speed
• Recipe duration
• Recipe output
• Consumer stress requirements

Item, Fluid, and Redstone Ports

Precision Spaces can connect to the outside world using dedicated ports.

Item Couplers

Move items between full-size Create logistics and inventories inside the Precision Space.

Belts, funnels, chutes, and other Create logistics still work normally.

Fluid Couplers

Move fluids across the scale boundary while keeping Create pumps, pipes, valves, and pressure meaningful.

Redstone Ports

Send redstone signals between the normal world and the miniature factory.

Useful for:

• Machine controls
• Clutches
• Sensors
• Shutdown systems
• Compact logic

Universal Precision Port

The Universal Precision Port can be configured for:

• Kinetics
• Items
• Fluids
• Redstone

This allows more compact and flexible factory connections.

Engineer's Goggles

Create's Engineer's Goggles work with Precision Engineering.

Inside Engineering Mode, goggles can inspect the actual miniature Create machines.

Kinetic diagnostics can also show information such as:

• Native-source multiplier
• Native capacity
• Scaled capacity
• Imported capacity
• Total available capacity
• Whether power is native or imported

Performance

Precision Engineering uses an optimized shared backend system designed to support many active Precision Spaces.

Optimizations include:

• Packed backend allocation
• Shared chunk loading
• O(1) backend lookups
• Sparse Block Entity indexing
• Per-cell synchronization
• Reduced kinetic and redstone updates

The goal is to keep real functional blocks inside each Space without requiring an expensive isolated backend for every block.

Moving Structures

Precision Engineering includes Sable-aware support for moving sub-levels and transformed structures.

Create Aeronautics / Simulated compatibility is optional and is not required for normal stationary Precision Spaces.

Alpha Status

Create: Precision Engineering is currently in Alpha.

The main systems are functional, but bugs, balance changes, compatibility problems, rendering issues, and save-related problems may still occur.

Back up important worlds before updating between alpha versions.

Build smaller. Engineer smarter. Fit an entire Create machine where one block used to be.
