What command allows you to substitute bodies and datums as well as reapply dependent features?

The command that allows for substituting bodies and datums while also reapplying dependent features is the Replace Feature. This command is particularly useful in design workflows where changes to a model are necessary. It facilitates the process of replacing one body or datum with another without losing the associations to features that depend on those entities.

When a body or datum is replaced using this command, all the features that rely on the original body or datum can be automatically updated to reference the new geometry. This is essential in maintaining the integrity of the design and ensuring that modifications do not disrupt the entire assembly or model.

The other commands listed do not provide the same level of functionality. For instance, Edit Feature allows you to change parameters or characteristics of an existing feature but does not support the substitution of bodies or datums. Swap Bodies specifically deals with exchanging one body with another in certain contexts but lacks the broader application of replacing datums and updating dependent features. Modify Datum focuses on adjusting the properties of a datum rather than replacing it outright. Hence, the Replace Feature command stands out as the best solution for the described task.
