Which Synchronous Modeling command can change the radii of a feature regardless of its history?

The Resize Blend command is specifically designed to modify features in Synchronous Modeling without any dependence on their history. This capability is particularly useful when working in environments where the design intent may require adjustments to existing geometries without reverting to the original feature definitions.

By utilizing Resize Blend, users can easily change the radii of blended features while maintaining the surrounding geometry's integrity. This allows for a more flexible design process, enabling rapid alterations and adjustments as needed.

In contrast, Move Face, Transform Blend, and Relate Face commands serve different purposes related to geometric manipulation or defining relationships in the model, but they do not have the specific functionality to resize blend features directly, particularly without taking historical context into account. This distinction highlights the unique capability of Resize Blend in Synchronous Modeling when it comes to efficiently managing feature modifications.
