Synchronous modeling commands work best on which types of faces?

Synchronous modeling commands are particularly effective when applied to analytical faces, which include geometrically defined faces like planes, cylinders, and cones. These faces are characterized by their mathematical definitions, allowing for precise manipulation and feature extraction. The modelling commands in synchronous technology leverage this definition to facilitate features such as direct editing, moving, or adjusting the faces without needing to rely on the underlying history of the model.

Analytical faces offer clear geometric relationships that make it easier for the software to understand the intent behind the design changes. This capability helps users to maintain design integrity while modifying models more intuitively.

While flat faces, curved faces, and composite faces can be manipulated using synchronous commands, they may not always yield the same level of precision and effectiveness as those with analytical characteristics. For example, curved faces could introduce complexities due to the varying geometries, and composite faces may involve multiple analytical curves that don't behave as straightforwardly as singular analytical faces. Hence, the best fit for synchronous modeling commands is on analytical faces.
