Symmetry Status of Panels

In the Hull application a panel may be symmetric, portside (PS) specific, starboard (SB) specific or be located in/over the center line.
In a symmetric panel the definition of each part will result in two physical copies, one used on PS, the other on SB. Furthermore, and independent of the symmetry status of the panel, it may be stored in the panel data bank either on PS or SB.
The symmetry status of the panel must always be explicitly specified when the panel is modelled and a try to model a panel without it will be prevented.
The symmetry status is specified via special codes that in the Design Language are corresponding to the following keywords.
|
SBPS |
Symmetric panel, valid in one copy for PS, another for SB |
|
P |
A PS specific panel. |
|
S |
A SB specific panel. |
|
SP |
A panel in/over the center line (CL), for example, a center line girder or decks and platforms with parts on both sides of the CL. |
P- and S- marked panels may well extend somewhat into the opposite half of the vessel but must not have complete parts stored on the "opposite" side. If so, they should be treated as SP panels instead.
(For curved panels there is a temporary exception to what is stated above. For them the symmetry must be controlled by suffixes of the panel names (P, S and SP corresponding to the equal codes above). Names of symmetrical panels should end in a digit. Moreover, all panels (except those over CL) should be described on PS.)
