Representation Styles

DRAW Reference Manual

Graphical Representation : Representation Styles

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


Tube flag	TUBEF	OFF
Centreline flag	CLIN	ON
Piping Symbol flag	PSYM	ON
Obstruction flag	OBSTF	OFF
Insulation flag	INSU	OFF
Profile flag	PRFG	OFF
P-line flag	PLFG	ON
Drawing Level	DLEV	6
Frontface Style/Colour	FFSTYLE/FFCOLOUR	SOLID/1
Centreline Style/Colour	CLSTYLE/CLCOLOUR	CHAIN/1
Backface Style/Colour	BFSTYLE/BFCOLOUR	OFF
Obscured Style/Colour	OBSTYLE/OBCOLOUR	OFF
Obscured and Backface Style/Colour	BOSTYLE/BOCOLOUR	<as Obscured>
Obscured and Centreline Style/Colour	OCSTYLE/OCCOLOUR	<as Obscured>
P-line Style/Colour	PLNSTYLE/PLNCOLOUR	LDASH/1
Member line Style/Colour	MLNSTYLE/MLNCOLOUR	OFF
Piping Insulation Style/Colour	PINSSTYLE/PINSCOLOUR	OFF

TUBEF, CLIN, PRFG, PLFG, PSYM, OBSTF and DLEV are standard AVEVA E3D™ display representation controls and are not described here. (Refer to Model Reference Manual for further information.)

The style/colour attributes allow different parts of chosen items to be drawn differently, and are used:

•

Frontface Style/Colour. In wireline VIEWs these attributes control the style and colour to be used to represent all edges. All edges display, except for holes that are drawn with a dashed line of the same colour as the FFCOLOUR. Set directly, for example:


FFSTYLE SOLID M FFCOLOUR 1	Use a SOLID line of MEDIUM thickness and Colour 1 for the frontface

FFSTYLE can be set to OFF to allow special effects.

•

Centreline Style/Colour. These attributes control the style and colour to be used for representing centrelines. They are also used for drawing LINE elements of Catalogue Components. When drawing pipework with TUBEF ON, CENTRELINE ON, the centreline is not obscured by the piping Components. (Unlike FFSTYLE, it is not necessary to superimpose two VIEWs with different Styles.

DRAWI elements owned by EQUI, SUBE, STRU, SUBS, or PTRA are drawn using the centreline style/colour of the STYL specified. For these DRAWIs the setting of the STYL’s centreline flag (CLFG) is ignored even though the centreline style/colour is used; the LEVEL attribute is used to control whether the DRAWI displays on the drawing. Set directly, for example,


CKSTYLE DASHED CLCOLOUR 1	Use a DASHED line of minimum thickness and Colour 1 for centrelines

•

Backface Style/Colour. In hidden line VIEWs, these attributes control the style and colour to be used to draw the rear edges of items (set to OFF by default). Set directly, for example,


BFSTYLE DOT BFCOLOUR 1	Use a DOTTED line of minimum thickness and Colour 1 for the backface

BFSTYLE is normally be set OFF for hidden line VIEWs, but if required can be used to set the style and colour to be used for drawing the rear edges of items. These attributes have no effect in wireline views. The example indicates the use of the Backface Style/Colour.

•

Obscured Style/Colour. In global hidden line VIEWs, these attributes control the style and colour used to draw the front-facing edges of items that are otherwise obscured by other objects (set to OFF by default). Set directly, for example,


OBSTYLE DOT OBCOLOUR 1	use a DOTTED line of minimum thickness and Colour 1 for obscured front facing edges

These attributes have no effect in wireline and local hidden line VIEWs. The example indicates the use of the Obscured Style/Colour.

•

Obscured and Backface Style/Colour. These behave in the same way as the Obscured Style/Colour but apply only when drawing backface lines that are also obscured. This allows obscured backface lines to be drawn in a different style/colour from other obscured lines, or switched off entirely. If these attributes are not set explicitly, they will match the Obscured style/colour. Once they are set explicitly on a style element, they will have their own values and will need to be maintained independently on that style element. Note that it is only possible to switch the Obscured and Backface style on, if both the general Obscured and Backface styles are also on.

Attributes BOSTYLE, BOCOLOUR

•

Obscured and Centreline Style/Colour. These behave in the same way as the Obscured Style/Colour but apply only when drawing centrelines that are also obscured. This allows obscured centrelines to be drawn in a different style/colour from other obscured lines, or switched off entirely. If these attributes are not set explicitly, they will match the Obscured style/colour. Once they are set explicitly on a style element, they will have their own values and will need to be maintained independently on that style element. Note that it is only possible to switch the Obscured and Centreline style on, if both the general Obscured and Centreline styles are also on.

Attributes OCSTYLE, OCCOLOUR

•

P-line Style/Colour. The attribute controls the style and colour to be used to draw p-lines. Set directly, for example:


PLNSTYLE CHAINED PLNCOLOUR 1	Use CHAINED lines of minimum thickness and Colour 1 for p-lines

PLNSTYLE can be set to OFF.

•

Member line Style/Colour. These attributes control the style and colour to be used to draw SCTN and GENSEC member lines. Set directly, for example:


MLNSTYLE SOLIDT MLNCOLOUR 1	Use a SOLID line of thickness 0.4mm and Colour 1 for member lines

MLNSTYLE can be set to OFF.

•

Pipe Insulation Style/Colour. These attributes control the style and colour to be used to draw Piping Insulation. Set directly, for example:


PINSSTYLE SOLIDT PINSCOLOUR 1	Use a SOLID line of thickness 0.4mm and Colour 1 for piping insulation lines

PINSSTYLE can be set to OFF. Piping Insulation is only drawn if the INSU flag is True.

The colour and linestyle functionality is described. Refer to Colours and Styles for further information.
