Create Shell Plate

Purpose:

To create or modify a shell plate.

Prerequisites:

The seams and butts forming the shell plate or shell plates must exist.

Instructions:

• In create mode, this function can be used either to create a single shell plate, or several plates generated by a grid of intersecting seams and butts. If a temporary plate has been created via the Developed Plate function in the View menu and is still selected, this one will be used as input to this function, and you will not be prompted to pick any seams and butts.

  In the single plate case you are prompted to indicate which seams and butts to use if no plate is selected. These must be indicated in a clock-wise direction when seen from the inside of the ship. The plate may have three to twelve edges. You must end the picking of seams and butts with Operation Complete.

In case you want to create several plates by a seam/butt grid, he will first be prompted to indicate butts from the aft end and forward. When the picking of butts has been finished with Operation Complete, you will be asked to indicate seams from the top or side of the ship and towards the centerline.

When all seams and butts have been picked, the plate data form will appear. This form is used to enter all main plate data such as symmetry information, position number, thickness, material quality, bevelling and excess. If several plates should be created at once, Auto Numbering may be checked to automatically set the position number of all plates. Only the position number of the first plate is then entered, and this number will be increased by one for each new plate. If All is checked, the entered plate data will be valid for all plates created. Otherwise, you will be prompted to fill in the form for every plate.

Finally, the plate name form must be filled in to give the plate names. If Add Posno is checked, the position number of a plate will be added at the end of the name given in the Plate Name field. The Auto Name check box is used to automatically form plate names. If Add Posno is also checked, this is done by adding a dash followed by the position number at the end. Otherwise, this is done the same way as for hull curves and storable planes.

• In modify mode, you can change the definition data of the shell plate. The same form is used as in create mode.

Options:

None.

Result:

• In create mode, one or more shell plates will be created and selected. The Select Submenu - Apply function must be used to commit the creation of the

• In modify mode, the shell plate will be updated with the new definition data and re-developed. To make changes permanent, Apply must be used. Using the Select Submenu - Deactivate function before the changes have been applied will undo them.
