# Preset Cuboid Dimensions
The Preset Cuboid Dimension allows teams to define a standard cuboid size per class - particularly useful for objects with known and consistent dimensions.

Helps reduce annotation time and improve consistency.

## Benefits
* Speeds up annotation workflows.
* Reduces human error and inconsistency across frames.
* Especially useful for frequently repeated or similarly sized objects (e.g., traffic cones, signs).

## Steps to Use Preset Cuboid Dimensions
Preset cuboid dimensions must be pre-configured in the Recipe for each class, with the help of enabling the [Preset Cuboid Dimension](/3d-multi-sensor-fusion/labeling/3d-multi-sensor-fusion-labeling-editor/drawing-tools/cuboid.md#preset-cuboid-dimension).
{% stepper %}
{% step %}
#### Navigate to 3D or BEV
Navigate to either 3D or BEV (Bird’s Eye View) mode, depending on your preference.
{% endstep %}
{% step %}
#### Choose a class
From the Class List, choose the class for which you want to create a cuboid annotation.
{% endstep %}
{% step %}
#### Start annotating
When you begin annotating, the tool will automatically generate a cuboid using the preset dimensions associated with the selected class - no need to start from scratch.
{% endstep %}
{% step %}
#### Adjust if needed
Experts can still manually resize the cuboid if needed, but starting with a predefined size significantly reduces repetitive effort and improves consistency.
{% endstep %}
{% endstepper %}
{% hint style="info" %}
If Preset Cuboid Dimension is toggled off in the recipe, the tool will use a standard cube dimension.
