# USDPrim.Attribute.ValueType.TupleDimensions

The shape of a value type’s components.

## Declaration

```swift
enum TupleDimensions
```

## Overview

Overview scalar: a single value (e.g. Float, Int). vector(n): an n-component tuple (e.g. Float3 is .vector(3)). matrix(rows:cols:): a 2D tuple (e.g. Matrix4d is .matrix(rows: 4, cols: 4)).
