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 as follows:


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	0
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
P-line Style/Colour	PLNSTYLE/PLNCOLOUR	LDASH/1
Member line Style/Colour	MLNSTYLE/MLNCOLOUR	OFF

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

If INSU is ON, Piping Component Insulation will be drawn using the frontface style and colour (FFSTYLE/FFCOLOUR). The outline of the piping Components will be hidden by the insulation in hidden-line views. If insulation and Components are required to be displayed, two similar views (that use different Styles) will need to be defined and superimposed.

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

•

Frontface Style/Colour. In wireline VIEWs these attributes control the style and colour to be used to represent all edges. All edges are shown, except for holes that will be 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 may 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 GRIDLN and LINE elements of Catalogue Components. When drawing pipework with TUBEF ON, CENTRELINE ON, the centreline will not be 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 will be drawn using the centreline style/colour of the STYL specified. For these DRAWIs the setting of the STYL’s centreline flag (CLFG) will be ignored even though the centreline style/colour is used; the LEVEL attribute should be used to control whether the DRAWI appears on the drawing. Set directly, e.g.


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, e.g.


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

BFSTYLE would 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. Refer to Figure 4:2.: Use of Backface Style/Colour (shown dotted) for an example of the use of the Backface Style/Colour.

Figure 4:2.

•

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


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. Refer to Figure 4:3.: Use of the Obscured Style/Colour (shown dotted) for an example of the use of the Obscured Style/Colour.

•

P-line Style/Colour. This 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 may 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 may be set to OFF.

P-line and member line styles and colours apply only to drawing steelwork Section elements.
