Using Names As Item Codes

Instruments are a special case. The instrument name (for example, FCV-70) will be incorporated into the description instead of being plotted in the item code area, because an instrument name may require more characters than the item code format permit.(the description is normally longer than the space allowed for the item code, and it will wrap onto the next line if necessary).

The material list item code for an instrument may be defined as either its PDMS name or its specification reference (SPREF) using the INSTRUMENTS command.

• When the NAME option is specified, the name will be appended to the description and the item code column will be blank.

• When the SPREF option is specified, the specification reference will be listed in the item code column.

  Component types that can be tagged, that is types that can have their names plotted automatically on the isometric drawing, can be treated like instruments. The types that can be tagged are:

  INST	VALV
  FILTER	PCOM
  TRAP	VENT
  VTWA	VFWA

  If you want a type of component to be treated like an instrument, you must give the component type a key number. The key number is related to its symbol key (SKEY) using the KEYS command.
