Which tool can be used to preview changes in the model before finalizing them?

The rollback bar is a powerful feature within SolidWorks that allows users to navigate through the history of a model's features. By moving the rollback bar backward in the Feature Manager Design Tree, a user can effectively preview the model in its state before specific features were applied. This capability is crucial for understanding how certain changes affect the overall design and can significantly aid in the decision-making process when modifying a model.

For example, if a designer is uncertain about how adding a new feature might impact the previous geometry or overall assembly, they can roll back to a point in the feature history to visually inspect the model before any destructive edits are made. This allows for experimentation and a better grasp of design intent without permanently altering the model during the iteration process.

The other tools mentioned have different functions. The Design Intent Tool focuses on understanding and defining the relationships and constraints within a model rather than previewing changes. The Feature Preview Tool is not standard terminology used in SolidWorks, making it less applicable in this context. The Graphics Area is where the model is displayed but does not provide any specific tools for previewing changes before application.
