Terminology

The following terminology is used for shell member. Shell profile is a common name for longitudinals and transversals modelled in the hull. In reality, the shell profile does not exist as a physical object. Instead, the shell profile is split up into smaller production pieces, called shell stiffeners. Thus, a shell stiffener can be part of either a longitudinal or a transversal. The location in space of the shell profile is determined by its trace curve. A shell profile may have more than one trace curve, each one defining a different part of the shell profile. However, a single shell stiffener always belongs to a single trace curve. Shell plates are the plates modelled in the hull. These are automatically developed as they are created.
