[Common Attributes](/cavalry/nodes/shapes/common-attributes.md) +

**Input Shape** - connect any other Shape containing sub-meshes. See [Sub-Mesh](/cavalry/nodes/behaviours/sub-mesh.md) for more info on sub-meshes.

**Level** - set the level within the sub-mesh's hierarchy to affect.

**Expand** - increase/ decrease the size of the bounding boxes generated.

**Minimum Size** - set a minimum width and height for the bounding boxes.

**Specific Indices** - enter specific ids for each sub-mesh to create a bounding box around. Enter comma separated values (e.g. `0, 4, 7`) or create ranges using colons (e.g. `1:4`) or a combination of both (e.g. `2, 3:5`).

{% hint style="info" %}
Remember that ids start at 0 so the first word in a string would be `id0`.

{% hint style="success" %}
Example usage:

1. Create a **Sub-Mesh Bounding Box** Shape.
2. Set its **Fill Color** to green.
3. Create a [Text Shape](/cavalry/nodes/shapes/text-shape.md).
4. Enter `Sub-Mesh Bounding Box` into the **Text** attribute.
5. Connect ***textShape.id > subMeshBoundingBox.inputShape***.
6. Set the **Level** to **2** (Words are the 2nd level of the sub-mesh within a Text Shape).
7. Enter `0,2` into the **Specific Indices** attribute.

Green boxes will be drawn around the words **Sub-Mesh** and **Box**.
