Which Synchronous Modeling command can be used to change the radii of a feature, regardless of the feature history?

The command that can be used to change the radii of a feature, regardless of the feature history, is known as "Resize Blend." This command operates in the Synchronous Modeling environment and allows users to modify the dimensions of fillet and blend features on a model without needing to access the original feature definition or history. This attribute is particularly beneficial in scenarios where rapid adjustments to the design geometry are required, enabling a more flexible and iterative design process.

The command is designed to allow manipulations that enhance productivity while working on complex assemblies or parts, where adhering to previous history might limit the adjustments you can perform. By utilizing "Resize Blend," designers can seamlessly alter the radii of specific features, streamlining the modification process and ensuring that design changes can be applied efficiently without being constrained by the sequence of operations that originally created the features.

Other options may not specifically allow for radius adjustments independent of feature history or may focus on different aspects of modeling. Therefore, the use of "Resize Blend" stands out as the appropriate choice in this context.
