CLEAVE

Split by color. Keyed to fit.

Cleave is a local-first 3D model splitting and fitting tool. Separate models along meaningful regions, create the connection you need, and export the resulting pieces for whatever you're building.

The process

Three steps. No guesswork.

01

Import & analyze

Bring in a supported model and let Cleave read the regions, materials, and geometry that are already there.

02

Split & key

Choose where pieces separate and how they reconnect. Use a peg, puzzle key, magnet pocket, or another fitting method.

03

Export & use

Export the resulting parts for printing, game development, fabrication, prototyping, or whatever your project needs.

Joint catalog

Three ways to key a seam.

PEG & SOCKET

Friction-fit connection with configurable clearance. Simple, strong, and easy to understand.

PUZZLE KEY

Interlocking geometry built into the seam for self-aligning parts and optional adhesive.

MAGNET POCKET

Recessed pockets for magnets with built-in clearance, designed for removable assemblies.

Local by design

Your models stay on your machine.

Cleave is designed as a desktop application. The core workflow can run locally on your computer, so your model does not need to be uploaded to a cloud service just to be split.

Offline workflow — no internet required for normal use.
No cloud processing — geometry work happens locally.
Updates when you want them — connect when a new version is available.
Cleave isn't about what you use the model for.
It's about making the model fit the way you need it to.”
Built for more than one workflow

One tool. Many uses.

🎮 Game Development

Create modular pieces, break apart assets, and prepare components that need to connect.

🖨️ 3D Printing

Separate multicolor or oversized models into pieces and add physical alignment or locking features.

🛠️ Making & Prototyping

Prepare physical builds, prototypes, props, models, and assemblies with controlled connections.
