The Representation Style (STYL) defines the appearance of the elements specified by a RRUL that references it. The STYL attributes, with their defaults, are:
|

|

OISTYLE/OICOLOUR |

|
TUBEF |
If unchecked, suppresses the display of all pipe outlines (corresponding to catalogue geometry with the 'Tube flag' TUFL set). |
|
CLIN |
If unchecked, suppresses the display of all centrelines (corresponding to catalogue geometry with the 'Centreline flag' CLFL set). |
|
PSYM |
If unchecked, suppresses the display of all piping components. |
|
OBSTF |
If unchecked, suppresses the display of all obstructions. |
|
INSU |
If unchecked, suppresses the display of any insulation. |
|
PRFG |
Used for steelwork. If unchecked, suppresses the display of steelwork profiles (corresponding to catalogue geometry with the 'Tube flag' TUFL set). |
|
PLFG |
Used for steelwork. If unchecked, suppresses the display of steelwork stick build representation (corresponding to catalogue geometry with the 'Centreline flag' CLFL set). |
|
EXTGPL |
Used for steelwork GENSECs. If checked, the member-line is extended to the intersection with the connected GENSEC member-line in the same framework. |
|
DLEV |
Only model elements with a representation level greater or equal to DLEV will be drawn. |
The style/colour attributes allow different parts of chosen items to be drawn differently.
Note:
An 'item' corresponds to a 'significant element' in the Model hierarchy which may
be composed of lower level elements. The concept of backface and obscured applies
to the item as a whole. The hidden parts of the item itself will be backface, but
parts of a different item below it will be obscured. For example, a FRMW or SBRF framework
is an item in this sense (as they are significant elements) and any GENSECs owned
by it are part of the same framework. GENSECs within a framework will not obscure
each other as they are part of a single item. However, GENSECs in one framework will
obscure GENSECs in a different framework (for global and universal view types).
