What type of models can synchronous modeling commands be used on?

Synchronous modeling commands in NX can be utilized on both history based and non-parametric models. This capability allows designers to take advantage of the flexibility and efficiency that synchronous modeling offers, regardless of the modeling approach used initially.

History based models typically rely on a sequence of operations recorded in the model's history tree, which can sometimes limit quick modifications. In contrast, synchronous modeling enables users to make changes directly on the model geometry without the need to follow a predetermined order of operations, making it faster and more adaptable.

Non-parametric models, on the other hand, do not depend on specific parameters and constraints, and they can be modified freely without the limitations imposed by a history tree. The ability to apply synchronous commands here means that users can directly manipulate the geometry with drag-and-drop actions, making revisions straightforward.

The correct answer encompasses the broad application of synchronous modeling techniques across different types of models, emphasizing the versatility of this approach in design workflows. This allows for a more dynamic and responsive design process, catering to a wide range of user needs and preferences.
