What command is utilized to duplicate a part and then modify it?

The command used to duplicate a part and then modify it is indeed "Move and Copy." This command allows users to create a copy of an existing part in a Solid Edge environment. When you execute this command, you can choose the original part you wish to replicate, and after copying it, you have the option to move the duplicated part to a different location within your assembly or design.

Once the part is duplicated, you can then modify it as needed—whether that means changing dimensions, editing features, or applying different materials. This makes it a highly useful feature for design processes where slight variations of a component are needed without starting from scratch.

The other options, while they may seem plausible, do not accurately describe the standard command used for this specific action in Solid Edge. Therefore, the "Move and Copy" command is the most appropriate choice for duplicating and modifying parts effectively.
