What counts as a line in the extracted list?

Any named line on the drawing - a stroke that carries a line number printed alongside it. Process pipework, utility headers, instrument air tubing, and flare / vent relief lines are all included. Anonymous strokes that carry no line number are excluded.

How is the line number read?

Each segment of the line number is matched against the conventions on the drawing: nominal size in inches or DN, material code (CS, SS, A106), service code, sequence number, and insulation / trace flags. The parsed fields populate their own columns so the line list is filterable, not a flat string.

Which line-numbering conventions are supported?

ASME B31.3 service classes, NORSOK piping classes, Shell DEP, Aramco SAES, and in-house operator conventions are parsed.

Are off-page connectors resolved into From / To?

Yes. When a line ends in an off-page connector, the connector tag is recorded in the From or To column. If the matching connector appears on a sister sheet, the two sides are reconciled into a single line entry.

How are utility, instrument, and flare lines separated from process lines?

Each line is classified into process, utility, instrument, or flare / vent. Classification uses the spec code, the line-stroke style on the drawing, and the connected equipment kind. The class is editable in review if the dialect is unusual.

What export formats are available?

Excel and CSV. The line list sits on its own sheet inside the same workbook as the I/O list and the equipment list, so one file covers all three documents.

Line list.

Every named line on the drawing. The line number is parsed into nominal size, material spec, service code, and sequence, then paired with the source and destination equipment from the drawing topology.
