Catalogues and Specifications
Reference Manual
Specification Constructor
These Specifications govern the choice of components from the catalogue. They must have been set up, together with the rest of the Catalogue DB, before design work takes place. In principle, therefore, SPECONMODE within PARAGON will be one of the first modules to be used when a new AVEVA E3D™ project is initiated, although in practice it is likely that a company-wide library of Catalogues and Specifications will be created independently of any individual design project and accessed by subsequent users to make sure overall standardisation and quality control.
The part of the hierarchy below a Catalogue element which is relevant when considering Specifications is shown in Figure 11:1.: Part of the structure of a CATA element. (The options CATE, STCAT and TEXT have been omitted; see Catalogue Database Structure for a fuller explanation.)

Piping Section and Structural Section elements are administrative STSECT subdivisions of the owning CATA element.

Component elements hold the definitions of piping components. These definitions comprise pointers to GMSET (Geomset) and PTSET (Pointset) elements, plus lists of parameters which specify the exact type, size and geometry of each component (that is, the component’s Attributes, including its GTYPE).

structural components. These definitions comprise pointers to GMSET, FITT GMSSET, PTSET and PTSSET elements, plus lists of specific attributes, in a similar way to COMP elements.
|
|
|
Detailing Text elements hold text which may be used to describe components in schedules and on isometrics. (They also hold the SKEYs which define the symbols used to represent components in isometric drawings; refer to Symbol Keys.)
|
|
|
Material Text elements hold text which may be used to describe the materials of construction of the components.
