# MDLMeshBufferZone

The general interface for logical pools of memory used in allocation of related mesh data buffers.

```
protocol MDLMeshBufferZone : NSObjectProtocol
```

## Overview

The concrete type of a zone is often private—you obtain zones by creating them from a [`MDLMeshBufferAllocator`](/documentation/ModelIO/MDLMeshBufferAllocator) object, then use zones with allocator methods such as [`newBuffer(from:data:type:)`](/documentation/ModelIO/MDLMeshBufferAllocator/newBuffer(from:data:type:)) when you need to ensure that related buffers are allocated together.

## Topics

### Inspecting a Zone

[`allocator`](/documentation/ModelIO/MDLMeshBufferZone/allocator)

The allocator object that created the zone.

[`capacity`](/documentation/ModelIO/MDLMeshBufferZone/capacity)

The data capacity of the zone, in bytes.
