When should a Shell feature be avoided in part design?

The Shell feature in part design is particularly useful for creating hollow components and reducing material usage, which can help with weight reduction. However, it should be avoided in situations where internal support is necessary. This is because using the Shell feature removes material from the interior, leaving the part hollow. If the design requires internal features or support, the Shell may eliminate vital material that contributes to the structural integrity and stability of the part.

In situations where complex shapes are involved, the Shell feature can still be effectively utilized, as it can often accommodate various geometries. Similarly, when aiming for lightweight models, the Shell feature is beneficial due to its ability to remove unnecessary material. The concern arises primarily with scenarios where precise control over wall thickness is crucial, which is where accurate thickness may become challenging if the geometry is intricate or requires specific internal features. Thus, understanding when the Shell feature compromises the necessary support for the part is key to effective design.
