Create Aeronautics : Easy Assembly (CAEA)
A lightweight add-on for Create Aeronautics that adds a versatile Chisel for assembling and disassembling physics structures.
✨ What does this mod do?
This mod adds a single, powerful tool: the Chisel. It functions as a portable physical assembler — turning any block structure into a physics entity, or breaking it back down, with just a click.
🛠️ The Chisel – Two Modes, One Tool
| Action | Mode | Effect |
|---|---|---|
| Left Click | Assemble | Turns a block structure into a physics entity |
| Right Click | Disassemble | Instantly breaks a physics entity back into blocks (⚠️ Disassembly will fail on fast-moving entities) |
- Survival Mode: Hold left-click for 1 second (20 ticks) to assemble — prevents accidental triggers.
- Creative Mode: Single-click assembly for fast iteration.
The Chisel has 64 durability. Both left-click and right-click consume 1 durability per use. It also accepts the same enchantments as the vanilla Brush — Unbreaking, Mending, and Curse of Vanishing — applied via anvil.

🤖 Deployer Support
Place a Chisel in a Deployer and it will automatically assemble/disassemble structures in your contraptions.
- Attack Mode: Assembles
- Use Mode: Disassembles

⌨️ Admin Commands (OP Level 2)
/caea assemble <x> <y> <z> [dimension]— Assemble at a specific position/caea disassemble <x> <y> <z> [dimension]— Disassemble at a specific position/caea disassemble all— Disassemble all loaded physics structures in the current dimension/caea delete <x> <y> <z> [dimension]— Delete a physics structure without returning blocks/caea delete all— Delete all loaded physics structures in the current dimension
⚠️
disassemble allanddelete allonly affect loaded structures. Unloaded structures are not processed.
⚙️ Configuration
The mod exposes a common config file (config/create_aeronautics_easy_assembly-common.toml):
chiselDisassemblySpeedCheck(default:true) — If enabled, the Chisel cannot disassemble structures that are moving too fast. Disable this to clean up stuck vehicles, at the risk of physics engine instability.
🎯 Why download this mod?
- Save time: No more long commands or complex tools — one Chisel does it all.
- Automate: Use Deployers to handle assembly/disassembly in your factories.
- Lightweight: Adds just one item — no bloat, no performance impact.
