Single Line Representation Administration

Draw provides support for structural Single Line Representation (SLR) drawings, in which structural model elements can be represented in a simplified form consisting of a single member line with an inline rectangular widget which indicates the type and orientation of the structural profile. The appearance of the SLR representation can be controlled via rules and styles, additional attributes are provided to specify the size and position of the widget.

The widget shape is obtained from the design representation derived from the catalogue data and GTYPE of the GENSEC element.

Single line representation is achieved primarily through the definition of representation rules referencing SLR-specific representation styles. Refer to Structural Single Line Representation Styles for further information.. Examples are provided in the AVEVA Sample Project (ruleset /TT/DRA/PRJ/REPRW/GEN/SLR and style library /TT/DRA/PRJ/STYLW/SLR).

Additional support is also provided.

View Reference Element

This is an attribute on the VIEW (VREFEL) that can be set manually to reference a structural model element, allowing the upping value on plan view widget labels to be determined. It can be referenced for other similar purposes by intelligent text and is not otherwise used by the application.

Autolabels

Automatic annotation of widgets can be obtained using standard autolabel functionality Refer to Autolabels, and Available Derived P-points for Single Line Representation of GENSEC Elements for further information.

It is expected that there will be more than one autolabel ruleset (DARST) to support various categories of SLR views, for example, elevation and plan views. Examples are provided in the AVEVA Sample Project (representation library /TT/DRA/PRJ/SLR/RULESETS/AUTOLABEL).

The SLR autolabel rules must reference specialist label text templates and label visual styles.

Note:
An SLR specific text template can be used in a plan view to display positions with uppings with respect to a view reference element. Example intelligent text is:

#DESC<FR CATREF> #PML(!!wrtViewReferenceElement('#PKCTOP^POSEU+'))

Where the global PML function !!wrtViewReferenceElement is supplied with the product and can form the basis for more customer-specific intelligent text PML functions.

View Styles

View styles are a useful aid because creating an SLR view with a suitable active visual style automatically gives an SLR view the correct autolabel rule set and representation rule attributes. Otherwise, the user must set these on a new VIEW manually. Examples are provided in the AVEVA Sample Project (representation library /TT/DRA/PRJ/SLR/VSTYLES).
