## Methods

### SubstituteGeometry

```luau
PartOperation:SubstituteGeometry(source: Instance)
```

- Tags: Capabilities: Basic + CSG

Substitutes the geometry of this [`PartOperation`](https://rapi.sleaze.dev/classes/PartOperation.md) with the geometry of another [`PartOperation`](https://rapi.sleaze.dev/classes/PartOperation.md).

Parameters:

- `source`: The [`PartOperation`](https://rapi.sleaze.dev/classes/PartOperation.md) whose geometry will substitute the geometry of this [`PartOperation`](https://rapi.sleaze.dev/classes/PartOperation.md).
