A part model created in Solid Edge is a combination of what?

In Solid Edge, a part model is primarily described as a combination of features. Features are the fundamental building blocks of a part model and represent specific operations or geometrical elements that define the shape and characteristics of the part. These can include basic features like extrusions, lofts, and revolutions, as well as more complex operations like fillets or patterns.

While solid bodies, surfaces, and sketches are all important components in the modeling process, they do not fully encapsulate the entirety of a part model. Solid bodies consist of the physical volume of a model, which is a result of the features applied. Surfaces can be involved in creating more complex shapes, but they are typically used in advanced modeling scenarios. Sketches serve as the foundational 2D outlines or profiles from which features are derived, yet they are only the starting point and don't define the complete model on their own.

Thus, features are the correct term to represent the combination of operations and shapes that constitute a part model in Solid Edge, making it the primary answer in this context.
