Shell Profile - Create

Purpose:

To create a longitudinal or transversal.

Prerequisites:

None.

Instructions:

• In create mode, the user must give a curve definition and shell profile data, which includes symmetry information, profile type and dimensions, material orientation, If a curve is already selected, it will be used as the trace curve. If several curves are selected, the shell profiles may be automatically named. In this case, the user must enter the first profile number, which will then be increased by 10 for longitudinals and 1 for transversals.

The profile may be symmetric (if the curve is defined on portside), port side specific (again, curve defined on portside), starboard specific (if the curve is defined on starboard) or over the centerline (if the curve extends over the centerline).

Profile type and dimensions can be entered in the form or selected from lists. The profile data can also copied from another shell profile (Same As).

• In modify mode, the user may change any part of the shell profile, including its name and box. The Modify Curve button lets the user change the curve definition, and the Modify Box button is used for changing the shell profile box. Since the shell profile is trimmed with the box, the extension of the profile can be changed by modifying the box coordinates. If several shell profiles are selected, All may be checked to make the same changes to all of them. The Same Box For All check box may be used to set the same box for all selected shell profiles.

Options:

Use the Option button for advanced selection methods.

Result:

• In create mode, a new shell profile will be created and selected. A single shell stiffener will also be created extending along the whole profile. The Store function may be used to store the shell profile and the shell stiffener on the hull structure data bank.

• In modify mode, the shell profile will be updated with the new definition data. To make the changes permanent, Store must be used. Using the Skip function before the shell profile has been stored will undo the changes.
