Watertight - [source code]
Combine a multi-part building mesh into a single watertight, CFD-ready solid via the bundled Python mesh service (trimesh/manifold3d/pymeshfix). The server auto-starts locally on the first run (uv-managed Python environment; first start installs it, 1-2 minutes) and is reused afterwards.
Input
| Name | Nickname | Description |
|---|---|---|
| Mesh | M | Input meshes (merged and combined into one solid). |
| Min Length | L | Vertex weld tolerance in model units. Two vertices closer than this are merged. Default 0.1 (10 cm for meter-unit models). |
| URL | MetaBlock API base URL. | |
| Run | Process the mesh — auto-starts the local server on first run. Resets when the result arrives. |
Output
| Name | Nickname | Description |

| Combined | M | Combined watertight CFD-ready solid mesh. |
| Status | S | Status message. |
