The shell profile element models a complete longitudinal or transversal. The shell profile may have one or several branches:

Each branch has a curve definition and a number of shell stiffeners:

The trace curve is defined as any other curve, as in the "Seam" or "HullCurve" element. Please see section Seam Element.
The name of the shell profile is given in the "ObjId" element of ShellProfile element itself:
|
ObjId |
The complete name of the shell profile (including the long/trans group name), e.g "SPT10", "PROFILE30". |
|
SubType |
The type of shell profile. Possible values are ‘Long’ for longitudinal and ‘Trans’ for transversal. Required attribute. |
Other attributes in the shell profile element are:
|
Delete |
If this attribute is "true" then the shell profile will be deleted before it is regenerated. Optional attribute, the default value is "false". |
|
Skip |
If Skip = "true" then the program will ignore this object description. The combination Delete = "true" and Skip = "true" will delete the shell profile but not generate a new one. Optional attribute, the default value is "false". |
