Spec Headings

A specification comprises of tabulated data where each headed question column represents a SELE and each horizontal row represents a SPCOM. There are four distinct sorts of information in a header:

• TYPE is the generic type (GTYPE) of the component represented by an SPCOM.

• NAME is the unique identifier for each SPCOM.

• Selector Questions define the SELEC choices which will be used to choose an appropriate SPCOM for a given design purpose (for example, STYPE, ANGLE etc).

• Reference Pointers link each SPCOM to the corresponding definitions in the other parts of the Catalog (for example, CATREF points to SCOM, DETAIL points to DTEXT, and so on).
