Line Data Report¶

The Line Data report is a coordinate listing for every measured line definition in the active tunnel. It does not compute deviations — use Line vs Theoretical Report or DR Trend / Stats Report for DR analysis. The report answers three practical questions:

Which sections contain data for each measured line?
How many measured points are in each (section × line)?
What are the exact section-local coordinates — and, when horizontal geometry is available, the world X/Y/Z — of every measured point?

Dialog¶

Open Reports → Line Data… from the main menu.

Control	Effect
From / To	Restrict the report to sections inside the chainage band. Pre-filled with the alignment’s start and end chainage when the dialog opens; edit to narrow the band.
Line Definitions	Tick the measured line definitions to include. All measured lines of the tunnel are listed; template lines are never offered here.
Mode — Summary	Produces only the Point-Counts table (one row per section × line).
Mode — Full Detail	Produces the Point-Counts table followed by Per-Point Detail pages.
Format — PDF / XLSX	Output type.

Default selection: all line definitions ticked, Mode = Full Detail, Format = PDF.

Point-Counts table¶

Always emitted, regardless of Mode. One row per (section × line) combination:

Column	Content
Chainage	Station formatted km+m (e.g. `0+125.500`).
Section	Section name as stored on the cross-section.
Line	Measured line definition name.
Points	Number of measured points the line currently has in that section.

The table is sorted by chainage ascending and, within the same chainage, by line name. Sections where a line has no points are still listed with Points = 0 so gaps in survey coverage are visible at a glance.

PDF output¶

Rendered as a continuous table on A4 portrait pages. Column headers repeat at the top of every page. Zero-point rows are shown in light grey so the eye skims past them.

XLSX output¶

One sheet named Counts with a header row and one data row per entry. All point counts are written as integers.

Per-Point Detail¶

Emitted only in Full Detail mode. One row per measured point, grouped by section then by line.

Every row reports the section-local coordinates — the (X, Y) of the point expressed in the section’s own frame, where X is horizontal offset from the axis and Y is elevation relative to the axis. When the alignment has horizontal geometry configured (non-empty Engine.HGeometry), the world X/Y/Z columns are also filled. When no horizontal geometry is available the world columns render - and the report still produces a complete section-local listing.

Columns¶

Column	Content	Notes
Chainage	Station of the section.
Section	Section name.
Line	Line definition name.
Layer	Line’s layer name (from the line definition).
Colour	Colour swatch of the line.	Rendered as a filled rectangle in PDF, as a hex value in XLSX.
#	Zero-based point index within the line.
Sect X	Horizontal offset in metres.	Negative = left of axis.
Sect Y	Elevation relative to the section’s axis point, in metres.	Negative = below axis.
World X	Easting in metres.	`-` when horizontal geometry is missing.
World Y	Northing in metres.	`-` when horizontal geometry is missing.
World Z	Elevation (height) in metres.	Computed from `SetoutOffset`’s `PointHeight`.

The world transform calls Alignment.Engine.SetoutOffset(Station, SectX, SectY) for each measured point. This routine places the point on the alignment’s 3-D geometry, so bearings and super-elevation are honoured: the world X/Y is where the point actually sits on the ground, and World Z is that point’s terrain-referenced height.

Colour column¶

The colour column shows the colour as configured on the line definition. In the PDF report it is rendered as a filled rectangle so that a reviewer can match ink on paper with what they see on screen (see Line definitions). In XLSX the same column holds the 6-digit hex code (e.g. #2F7FBF) so that conditional-formatting rules can still pick it up.

Tip

The Line Data report is the fastest way to hand raw survey data to an outside party. Export the Full Detail PDF for a signed-off paper copy, and export the XLSX for onward processing in spreadsheet software.

PDF layout¶

A4 portrait, 15 mm margin on all sides.

Page 1 — Counts: tunnel and project header, then the Point-Counts table.
Pages 2+ — Detail: one continuous table, paginated. Each page repeats the header row.

A footer line is drawn across the bottom of every page with the page number and the project/tunnel name.

XLSX layout¶

Two sheets:

Counts — the Point-Counts table.
Detail — the per-point rows, written only when Full Detail is selected.
