You can scale a part or surface model about its centroid, the model origin, or a coordinate system.

The Scale feature scales only the geometry of the model, for use in data export, cavities, and so on. It does not scale dimensions, sketches, or reference geometry. With multibody parts, you can scale one or more bodies.

A Scale feature is like any other feature in the FeatureManager design tree: it manipulates the geometry, but it does not change the definitions of features created before it was added. To temporarily restore the model to its unscaled size, you can roll back or suppress the Scale feature.
