What is a key difference between a Design Group and Feature Group?

A Design Group is specifically utilized to manage the updating of a model during the design process. It acts as a tool that allows you to encapsulate certain features or sets of features within a group, enabling you to control how they interact with the overall model. When changes occur in the Design Group, it can affect the associated features systematically, ensuring that the design remains coherent and manageable. This grouping mechanism is particularly useful in complex models where modifications to one part of the design might necessitate adjustments elsewhere.

In contrast, while organizing the model is an important aspect of both groups, the primary function of a Design Group revolves around update control, making option D the most accurate distinction. Further, a Design Group can indeed be deleted or made active, but those options do not emphasize the unique capability of controlling model updates, which is central to effective design management in Siemens NX.
