ISODRAFT Reference Manual

Function:

Specifies the level at which a change of pipeline specification is noted, and which changes are recorded on the isometric.

Description:

Pipeline specification changes are indicated by notes against the corresponding points on the isometric plot. By default, specification changes are noted at component level, but they can be noted at Branch level instead. SPECBREAK BRANCH causes only changes in the Branch specification to be recognised. SPECBREAK COMPONENT causes the Branch specification to be ignored and changes to be recognised only in the component attributes LSTUBE or SPREF, or in the Branch attribute HSTUBE. The format in which a specification change is shown is that both the original and new specifications are shown at each point of change. The format is similar to that used for dimensioning. The following Atext defaults are associated with the specification breaks on the drawing area:

	Specification	Specification ATEXT	Spec Break ATEXT
	Pipeline name	288 ‘PIPE’	288 ‘PIPE’
	Material spec	253 ‘PIPING SPEC’	289 ‘MATL’
	Insulation spec	270 ‘THERMAL INSULATION SPEC’	290 ‘INSUL’
	Tracing spec	271 ‘TRACING SPEC’	291 ‘TRACE’
	Painting spec	272 ‘PAINTING SPEC’	292 ‘PAINT’

Examples:	SPECB COMP Recognises changes in component specifications only. SPECB BRAN Recognises changes in branch specifications only. SPECB BRAN SPECC ON Recognises changes in branch specifications only, and outputs specification changes for insulation, tracing and paint.
