Shell Profile Numbers

There are currently some rules for the numbering of shell profiles that should be adhered to (see the figure below). They are to some extent temporary. Violation of these rules will mainly affect the automatic generation of shell profile sections in symbolic hull views.

• The numbers should always be integer numbers.

• Longitudinal numbers should be multiplied by 10 compared to their numbers in drawings, This is in order for the numbers of "inserted" longitudinals towards the ends of a ship to be integers as well.

• The numbers should be in the range 5 - 999.

• When output in drawings the number will be divided by 10.

• The number of longitudinals in the deck should be increased by 1000 compared to the shell longitudinals at the same distance from the Centre Line. The deck longitudinals are referred to by the increased number but before being output in views the added 1000 will be subtracted.

• Longitudinals that are specific for starboard should have their numbers increased by 2000 compared to the longitudinal in the same position on portside. This is valid for profiles both in the shell and in the deck. Thus starboard specific longitudinals in the deck should have numbers, larger than 3000.

• There are similar rules for the numbering of transversals.

• The numbers of transversals are normally equal to the frame numbers but must not be negative. However, they may be multiplied by 10 in case there the ship has half frames.

• The transversal numbers should be in the range 1 - 4999.

• Starboard specific transversals should have their numbers increased by 5000 (which is subtracted when the number is output in drawings/views).

• There are no specific rules for the numbers of transversals in deck. Their numbers may for example, be increased by 1 compared to the shell transverse.
