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

The command that allows you to substitute bodies and datums as well as reapply dependent features is the Replace Feature command. This functionality is particularly useful in a design process where changes to geometry or components might be necessary. When using the Replace Feature command, you can effectively swap out one body or datum for another while ensuring that any features that depend on the original are automatically adjusted to work with the new element.

This is advantageous because it preserves the relationships and associations within the model, so designers can maintain the integrity of their design intent without needing to regenerate or rebuild features from scratch. By leveraging this command, users can streamline the process of modifying existing designs, saving time and reducing the potential for errors that could arise from manual adjustments.

The other options don't offer the same level of functionality for substituting bodies and managing dependent features. For instance, ordering features or using copy/paste methods doesn't inherently support the reapplication of dependencies or the maintenance of features linked to the original geometry. A Feature Group allows for organizing features but does not facilitate the direct substitution of bodies or datums. Thus, the Replace Feature command stands out as the most appropriate choice for those tasks.
