Specifications

Specifications govern the choice of component available for selection in the catalogue, the specifications must be set up before any design work can be carried out. The specifications which define the components are held in a tabular format and are stored in the database as the specifications hierarchy.

Both the Specification World and Specification elements are administrative elements common to all disciplines in AVEVA Catalogue. Refer to the individual discipline for further information on the specification functionality available.

Create Specification World

The specification world (SPWL) element is an administrative element which allows the segregation of particular types of components in the hierarchy. These elements are held at the same hierachical level as the CATA elements.

Use the Create Specification World window to create a new Specification World element (SPWL) in the catalogue hierarchy, the functionality is common throughout all disciplines, refer to Multi-Purpose Windows for further information.

Create Specification

A Specification (SPEC) element is equivalent to an engineering specification for a given class of component. It may contain all components of a given material, for example carbon steel, or all components for a given class of use, for example all piping components with a particular pressure rating. For a detailed explanation of a Specification refer to Specification Constructor for further information.

Use the Create Specification window to create a new SPEC element in the catalogue hierarchy, the functionality is common throughout all disciplines, refer to Multi-Purpose Windows for further information.

Note:

A SPEC element must be created below a SPWL element.

Specifications comprise of tabulated information and can contain any number of seperate tables. Refer to Content and Format of a Specification and How Component Selection Works for further information. On all windows click Apply to commit the inputs or changes or Back to return to the list of tasks.

The Specifications window acts as a task hub where specifications can be created and/or modified, the window can be divided into two areas.

At the top of the window is a CE option which populates the window with the currently selected element in the Catalogue Explorer.

If the CE option is used, the drop-down to the right acts as a History which allows the selection between specification elements which have been selected while the window has been displayed.

The Headings drop-down acts in a similar way allowing selections between the component GTYPEs of the specification. Refer to Headings for further information.

A grid area lists the items assigned to the Specification. Directly below are the following options:


Eng. View	displays the items in the grid list in engineering view
CAD View	displays the items in the grid list in CAD view
Select All	highlights all of the items in the grid list
Clear Selection	removes the highlight from the items in the grid list

CAD Attributes allows changes to be made to the references to reference attributes of the piping specification. These point to the material, fluid, bolting specification and any user defined Nominal Bore/Branch/Reducer tables.
