Dimensional Scratchpad
Dimensional Scratchpad is a Forge mod for 1.20.1 that gives each player a private 64-block cube dimension for planning builds away from the main world.
What it does
Each player receives a personal 64-block cube inside a separate dimension, and building happens only within that cube. Designs can be planned there without changing the survival world, and the player can return to the original world at any time. Teleporting between the two is close to instant, so testing a build in the main world does not require leaving for a separate creative world.
The mod is meant for single-player worlds and multiplayer servers alike. In multiplayer each player's cube is assigned to that player alone. The mod is installed on Forge for 1.20.1 only, and it runs on client and server, so both the server and every player need it. The code is open source under the MIT License, and public links exist for the source code and the issue tracker.
Key features
Private build cube
Each player gets a 64-block cube in a separate dimension to plan designs in, kept apart from the main world.
Near-instant travel
Moving between the scratchpad and the original world takes almost no time, so builds can be checked quickly.
Restricted actions
Inventory items cannot be modified, enchanting and ender chests are blocked, and hostile mobs from the main dimension cannot reach the player.
Size limit by design
The 64-block limit is deliberate, keeping the space small and private, much like a real scratchpad.

Use cases
Planning builds
A builder can sketch and test a structure in the cube before placing it in the survival world.
Multiplayer building
A server can give each player a separate cube, so players design without interfering with one another.
Who it’s for: Builders, creative players and server owners who want a separate planning space inside a survival or multiplayer world. Players who need unrestricted creative building may prefer a full creative world.
Questions
