Profiles in the Shell

Shell profiles may be divided into longitudinal frames (or longitudinals for short) and transversal frames (or transversals). As has been described in ref. HG 2 longitudinals and transversals consist of objects on two levels, the shell profile and the shell stiffener.

The shell profile object collects all shell stiffeners belonging to a certain longitudinal/ transversal and that are referred to by a number and it does not itself contain any physical profiles. The actual profile information (one profile per object) is stored in the shell stiffener object.
