2.5.11. Export

The Export menu collects:

  • Export ▸ LandXML… — full LandXML 1.2 with the entire data model.

  • Export ▸ GSI… — Leica GSI files for the Road Runner family.

  • Export ▸ PSYMO (S01 / S02 / S03)… — Greek PSYMO files; writes .S01 (horizontal PIs), .S02 (vertical PVIs, radius form) and .S03 (superelevations) next to the chosen file name, skipping any part for which the alignment has no data (a summary lists what was written).

  • Export ▸ ASCII Horizontal / Vertical Elements… — the comma-delimited element lists documented below.

  • Export ▸ ASCII Cross-Section Data ▸ … — one command per cross-section collection: Superelevation Left / Right, Horizontal / Vertical Offset, Superelevation Offset Left / Right, Widening Left / Right and Cant — the 4-column segment list documented under cross-section collections below.

  • Export ▸ Other Formats ▸ … — third-party interchange files: Trimble TGO ASCII (.tdf), Anadelta (.xyv), TCP-Tunnel Aplitop (.eje + .ras), Amberg GRP Office, NRG / NST string file (.nst) and Bentley InRoads ASCII — samples under Other interchange formats below.

  • (File ▸ Save / Save As) — native .alm round-trip.

S01 export requires a PI-based alignment (PIs solved in the Alignment Editor or imported from S01); an alignment that only has resolved elements (e.g. from LandXML) exports the element formats instead.

2.5.11.1. LandXML

LandXML 1.2 is the recommended interchange format. The writer emits a full Alignment document with the resolved horizontal element list (lines / arcs / clothoid spirals / cubic parabolas), the vertical PVI / element list and the optional station-equation elements. When 3D mode is on, the Alignment element also carries mode3D="true" and sectionRefAzimuth (radians); both round-trip on import (see 3D mode and vertical shafts). Sample output (truncated):

Note

On a clothoid the Chainage is the chainage at the first point and StartChainage is the chainage at the inflection (zero curvature). They coincide for an entry clothoid (where the transition leaves a straight) and differ for an exit clothoid.

2.5.11.3. ALM ASCII — cross-section collections

All cross-section collections (Horizontal/Vertical Offset, Superelevation L/R, Superelevation L/R Offset, Widening L/R, Cant) share the same comma-delimited segment-list shape, one row per linear-interpolation segment:

chainage, startValue, chainage, endValue
chainage, startValue, chainage, endValue
...

Example — Superelevation Left (%):

300.000, -0.940, 320.740, -5.500
320.740, -5.500, 420.280, -5.500
420.280, -5.500, 445.290,  0.000
...

Example — Widening Left (m; ramp in, hold, ramp out):

100.000, 0.000, 125.000, 0.380
125.000, 0.380, 150.000, 0.380
150.000, 0.380, 175.000, 0.000

Example — Vertical Offset (m; e.g. a construction-stage grade shift over a station range):

0.000,   0.000, 1250.000, 0.000
1250.000, 0.000, 1300.000, -0.150
1300.000, -0.150, 2100.000, -0.150

Available under Export ▸ Other Formats. Bearings are surveying azimuths in gons (NRG uses radians); signed radii are negative for clockwise (right) turns; the spiral parameter is A = √(R·L).
