Synchronous modeling commands are best suited to be used on what types of parts?

Synchronous modeling is a powerful feature within Siemens NX that allows users to make rapid and flexible modifications to a model. It's particularly effective for parts that do not have a parametric history, which means they do not rely on a sequence of defined steps or features to maintain their geometric integrity. In this context, parts with prismatic bodies but without parametric history are ideal candidates for synchronous modeling.

The advantage of using synchronous modeling on these types of parts lies in the ability to directly manipulate the geometry without worrying about the underlying constraints and relationships typically associated with parametric modeling. Users can easily push, pull, and reshape features regardless of their original creation order, making it a versatile approach for both new designs and modifications.

In contrast, parts with parametric history may require a more controlled approach, as changing one feature could significantly affect others. Additionally, while surfaces and convergent bodies can also be manipulated in NX, they may not benefit from synchronous modeling in the same way that prismatic bodies without parametric history do. Synchronous modeling shines where direct geometric edits are paramount, allowing for greater design freedom and efficiency.
