### *class* RASizeDistribution

Rocky PrePost Scripting wrapper for a single entry in a single Particle’s size distribution list.

Access this wrapper from a given [`RAParticle`](RAParticle.md#generated.RAParticle) with:

```python
size_distribution_list = particle.GetSizeDistributionList()
distribution_1 = size_distribution_list.New()
distribution_1.SetSize(1.0, 'm')
distribution_1.SetCumulativePercentage(100)

```

**Methods:**

NameDescription[`GetCumulativePercentage`](#generated.RASizeDistribution.GetCumulativePercentage)()Get the value of "Cumulative Percentage".[`GetScaleFactor`](#generated.RASizeDistribution.GetScaleFactor)(\[unit\])Get the value of "Scale Factor".[`GetSize`](#generated.RASizeDistribution.GetSize)(\[unit\])Get the value of "Size".[`SetCumulativePercentage`](#generated.RASizeDistribution.SetCumulativePercentage)(value)Set the value of "Cumulative Percentage".[`SetScaleFactor`](#generated.RASizeDistribution.SetScaleFactor)(value\[, unit\])Set the value of "Scale Factor".[`SetSize`](#generated.RASizeDistribution.SetSize)(value\[, unit\])Set the value of "Size".<a id="generated.RASizeDistribution.GetCumulativePercentage"></a>

#### GetCumulativePercentage()

Get the value of “Cumulative Percentage”.

<a id="generated.RASizeDistribution.GetScaleFactor"></a>

#### GetScaleFactor(unit: Optional\[str\] = None)

Get the value of “Scale Factor”.

- **Parameters:****unit** – The unit for the returned value. If no unit is provided, the returned value will be in “-“.

<a id="generated.RASizeDistribution.GetSize"></a>

#### GetSize(unit: Optional\[str\] = None)

Get the value of “Size”.

- **Parameters:****unit** – The unit for the returned value. If no unit is provided, the returned value will be in “m”.

#### SetCumulativePercentage(value: Union\[str, float\])

Set the value of “Cumulative Percentage”.

- **Parameters:****value** – The value to set. This value can be an expression with input variables or float type.

<a id="generated.RASizeDistribution.SetScaleFactor"></a>

#### SetScaleFactor(value: Union\[str, float\], unit: Optional\[str\] = None)

Set the value of “Scale Factor”.

- **Parameters:**
    - **value** – The value to set. This value can be an expression with input variables or float type.
    - **unit** – The unit for value. If no unit is provided, value is assumed to be in “-“.

<a id="generated.RASizeDistribution.SetSize"></a>

#### SetSize(value: Union\[str, float\], unit: Optional\[str\] = None)

Set the value of “Size”.

- **Parameters:**
    - **value** – The value to set. This value can be an expression with input variables or float type.
    - **unit** – The unit for value. If no unit is provided, value is assumed to be in “m”.
