### *class* RAGeometryCollection

Rocky PrePost Scripting wrapper for the collection of geometries in a project.

The class represents the “Geometries” item on the project data tree. To get the [`RAGeometryCollection`](#generated.RAGeometryCollection)from a [`RAStudy`](RAStudy.md#generated.RAStudy), use:

```python
geometry_collection = study.GetGeometryCollection()

```

This class contains methods to iterate and retrieve the geometries in a given project, manipulating the collection as a regular Python list, e.g.:

```python
for geometry in geometry_collection:
    print(geometry.GetName())

feed_conveyor = geometry_collection[1]
inlet = geometry_collection.GetGeometry('Inlet 01&gt;')

```

To create the different kind of geometries (conveyors, inlets and custom geometries), see [`RAStudy`](RAStudy.md#generated.RAStudy).

#### GetBoundingBox(time\_step: coilib50.time.time\_step\_interface.ITimeStep | None, force\_load: bool = False)

Get the bounding box containing all geometries in this collection, at the given time.

- **Parameters:**
    - **time\_step** (*ITimeStep*) –
    - **force\_load** (*bool*) –
- **Rtype (FixedArray, FixedArray):**
- **Returns:**The bounding box of all the geometries in the passed time step, or None if the box could not be computed.
