Which statement is true about the Create Assembly Features option?

The statement that it does not change the part files when creating a cutout is true. This means that when you use the Create Assembly Features option to add features like cutouts, these modifications are not permanent alterations to the original part files themselves. Instead, they are created as assembly-level features that only exist within the context of that specific assembly. This allows for greater flexibility in design since you can create variations, such as cutouts or other features, without having to modify the original parts or create new part files, thus keeping the original part data intact and reusable in other assemblies.

This functionality is crucial for efficient assembly design as it enables engineers to work with a base design and iterate on it without altering the fundamental characteristics of the part files. Therefore, when multiple variations of an assembly are needed, this approach can save time and maintain data integrity.
