The Use Object mode is particularly important for animating (size animation) and scaling of primitives via the axis.

When in Use Object mode you can modify and object as a whole. This means that the object's axis system will be modified and not its geometry.

This can in some cases lead to issues during the modeling phase or for animations. Objects can suddenly pulsate or become distorted.

These types of issues can generally be remedied using the Reset Axes function.

The effects scaling of the axis has can be found in the description of the Model mode.

TipUse the Use Object mode for the animation.
