What usually happens when you shell a part with uneven thickness?

When a part with uneven thickness is shelled, it can result in complex shapes that are challenging to manufacture. This occurs because the shell feature reduces the part's thickness uniformly around its surface, but if the original thickness varies significantly, the resulting geometry may lead to undercuts, thin areas, or difficult transitions. Such intricacies can complicate the manufacturing process, as specialized tooling or techniques might be necessary to achieve the desired outcomes.

The complexity also arises from the need to ensure that the final geometry maintains structural integrity and functionality, which may not always be possible with unevenly shelled components. This understanding is critical in both design and practical application, as it influences the manufacturability and overall performance of the part.
