What command allows you to store different expression configurations?

The command that allows you to store different expression configurations is the Parameter Table. Within Siemens NX, the Parameter Table serves as a central location where you can define and manage various parameters associated with your design. This includes setting up different configurations that can dictate how parameters behave in relation to one another, facilitating design variations based on different criteria or requirements.

By utilizing the Parameter Table, users can quickly switch between different configurations without the need to manually alter each parameter individually, which streamlines the design process and enhances efficiency. This capability is particularly crucial in complex designs where multiple configurations might be needed for different applications or presentations.

In contrast, other options don't specifically focus on the storage of expression configurations. The Expression Table typically deals with managing expressions rather than configurations. The Configuration Table refers more broadly to managing design configurations but does not emphasize expression handling. The Arrangement Table is often related to how components are organized or arranged in an assembly, rather than the specific task of storing expression configurations.
