Nothing below is defaulted. An input you leave blank makes the section it feeds NOT EVALUATED — never PASS, never CLEAR.

Alignment required LandXML file Alignment name optional Required only if the file holds more than one alignment. There is no “first one wins”.

Terrain required Study with accepted terrain Terrain uploaded to a study. Its raster placement is read from the file’s own transform. JSON elevation grid alternative

Raster origin X Raster origin Y Cell size m

The three above are needed only for a JSON grid.

Vertical datum required Carried, never invented. Absent, it reports UNKNOWN. Relative vertical accuracy σ m required* The third term of the grade measurement base. Not needed if you declare the base directly below.

Design criteria required CRS / EPSG required Authoritative, projected, in metres. HaulLens never infers a CRS and never reprojects.

Maximum grade % Design speed km/h Minimum radius m

Your numbers, not ours. There is no default 45 m and no default 10 %.

Minimum-radius basis, including design speed required A radius with no basis is not a standard this evaluation can validate against: the check reports UNKNOWN, not PASS. Grade measurement base m required* Declare this, or all four below. Without either, the base cannot be resolved and grade screening reports NOT EVALUATED. The base is never shortened because metadata is missing.

Wheelbase m kσ Grade discrimination

Truck reference required I accept the OEM reference configuration as the comparison basis

Not a Solomon configuration, no manufacturer endorsement, and not a model of your operating fleet. Cycle output is TRAVEL ONLY.

Constraints optional Formation width m optional Without it the formation footprint is NOT EVALUATED. No default road width is inferred and no OEM truck width is substituted. Exclusion polygons optional GeoJSON, already in the working CRS. HaulLens does not reproject and fails closed. Without a dataset, exclusions are NOT EVALUATED — never CLEAR.

What this evaluates

Geometrycontinuity, tangent continuity, cusp-freedom, self-intersection, and your declared minimum radius

Terrainelevation at the supplied geometry’s own exact stationing. No arc is approximated by its chord

Gradea sliding chord over your declared measurement base, against your declared limit

Haulageloaded out and empty back, each leg’s uphill and downhill state recomputed in that direction — TRAVEL ONLY

Exclusionsthe centreline and, if you declare a width, the formation footprint, against the exact primitives

EarthworksEARTHWORKS QUANTITIES — UNDER MODEL REVIEW. Absolute cut and fill are withheld

HaulLens does not generate the road, replace CAD, or claim construction readiness. Engineer review is required.
