### *class* RAParticleAssemblyPartList

Rocky PrePost Scripting wrapper for the parts list in a single Particle Assembly.

To get the [`RAParticleAssemblyPartList`](#generated.RAParticleAssemblyPartList) from a `RAParticleAssembly`, use:

```python
assembly_parts = particle_assembly.GetAssemblyParts()

```

[`RAParticleAssemblyPartList`](#generated.RAParticleAssemblyPartList) contains methods to add, remove and retrieve individual assembly parts. It corresponds to the list of entries on a Particle Assembly’s “Shape” tab on the Rocky UI.

The following examples add, remove and access individual entries in the assembly parts list:

```python
# Add new items
assembly_part_1 = assembly_parts.New()

# Access and modify items
assembly_part_2 = assembly_parts[0]
assembly_part_2.SetParticle('Particle 1')

# Remove items
assembly_parts.Remove(assembly_part_2)
del assembly_parts[0]
assembly_parts.Clear()

```

The [`RAParticleAssemblyPartList`](#generated.RAParticleAssemblyPartList) is a list of [`RAParticleAssemblyPart`](RAParticleAssemblyPart.md#generated.RAParticleAssemblyPart).

**Methods:**
