# Sandbox.PhysicsTraceBuilder.Size

## Overload 1

```csharp
PhysicsTraceBuilder Size(in BBox hull)
```

Makes this trace an axis aligned box of given size. Extracts mins and maxs from the Bounding Box.

### Parameters

- `in hull` (`BBox`)

### Returns

`PhysicsTraceBuilder`

## Overload 2

```csharp
PhysicsTraceBuilder Size(in Vector3 size)
```

Makes this trace an axis aligned box of given size. Calculates mins and maxs by assuming given size is (maxs-mins) and the center is in the middle.

### Parameters

- `in size` (`Vector3`)

### Returns

`PhysicsTraceBuilder`

## Overload 3

```csharp
PhysicsTraceBuilder Size(in Vector3 mins, in Vector3 maxs)
```

Makes this trace an axis aligned box of given size.

### Parameters

- `in mins` (`Vector3`)
- `in maxs` (`Vector3`)

### Returns

`PhysicsTraceBuilder`
