Identifying Pipeline Specification Changes

The level at which a change in specification is identified may be set to Component or Branch by using the SPECBREAK command.

Where there is a specification change part way through a section of pipeline, the new specification reference shows both the normal and new specification references by means of arrowed messages similar to those used for dimensions.

The normal specification reference for the pipeline will appear in the bottom right-hand corner of the isometric drawing, immediately above the pipeline reference.

Changes in tracing, paint, insulation and material specifications can also be shown.
