KEYS

Function:

Allows components with specified SKEYS to be treated like instruments.

Description:

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. This means that:

• If INSTRUMENT SPREF is set, the SPREF will be used as the itemcode.

• If INSTRUMENT NAME is set, the itemcode column will be left blank and the name will be appended to the description.

• If INSTRUMENT NAME WITH BALLOONS is set, the name will be output in a balloon on the isometric.

The types that can be tagged are:

INST  VALV  FILTER  PCOM
TRAP  VENT  TWA  VFWA

To treat a component type as an instrument, give each specific component type a key number, and then relate the key number to the symbol key (SKEY) by the KEYS command.

See the TAG command for further information about tagging.

Examples:

KEYS 1 ’VVFL’

Any valve with the symbol key VVFL, and which has a name, will have its name appended to its description and the itemcode column left blank. If a valve with the symbol key VVFL is not named, its SPREF will be output as its itemcode in the normal way.

KEYS 1

Remove the component from the key number list by quoting its number only.

where keynumber is the key number (which must be in the range 1 to 20) and skey is the symbol key (SKEY attribute).
