title: Rebuild Mesh

Refresh the proxy mesh of a Chisel object without doing a full conversion. Useful after changing primitive parameters, modifier targets, or anything that invalidates the cached proxy bake.

![Rebuild Mesh](../assets/rebuild.webp)

## When to rebuild

The proxy mesh is what shows up in non-Chisel render engines (EEVEE / Cycles / Solid view) and what BVH-based features (snapping, raycasting) operate on. The renderer rebuilds it automatically when needed, but a manual rebuild is sometimes useful after batch edits or if something looks stale.

Common reasons:

- Changed primitive type or parameters and the proxy didn't refresh
- Moved or scaled boolean targets
- Adjusted blend radius or rounding values
- Added / removed Chisel modifiers

## How to rebuild

1. Select the Chisel object.
2. Click **Rebuild Mesh** in the *Object Properties* panel, or open the pie menu (`Q`) and pick *Rebuild*.

The proxy mesh re-bakes using the current proxy mode and voxel size from [Render Engine → Display](../render-engine/display.md#proxy-mesh).

## Rebuild vs Convert

| Action | What it produces |
|---|---|
| [Convert to Mesh](convert.md) | New Blender mesh object, separate from the SDF |
| **Rebuild Mesh** *(this page)* | Refreshes the proxy mesh attached to the SDF object — does not create a new object |

Use *Convert* when you want a final exportable mesh. Use *Rebuild* when you just need the proxy refreshed for accurate snapping or non-Chisel rendering.
