XML Validate (R3XMLVALIDATE)

Command: R3XMLVALIDATE

Runs a pre-export validation check on a survey plan in the drawing and displays the results in a report dialog. Checks are based on the NSW LRS Digital Plan Validation Rules and R3Survey-specific checks.

Usage

  1. Type R3XMLVALIDATE at the command line
  2. Select any entity on the plan to validate (parcel, line, point, etc.)
  3. The validation report dialog opens showing all checks with PASS/FAIL/WARN results

Report dialog

The report shows a colour-coded table:

Result Colour Meaning
PASS Green Check passed
FAIL Red Check failed — must fix before export
WARN Yellow Warning — review recommended
SKIP Grey Check not applicable (e.g. compiled plan)
---- Grey Not yet implemented

Buttons:

  • Copy — copies the full report as plain text to the clipboard
  • Close — dismisses the dialog

LRS Rules (NSW Digital Plan Validation)

Rule Description
LRS-2 Every parcel has geometry (at least one line)
LRS-4 Survey region set (Urban/Rural)
LRS-5 Survey type set (Surveyed/Compiled)
LRS-6 Parcel misclose (1:8000) and area check for lots. Uses legal dimensions (rounded bearings/distances, same as R3LOTEDIT). Checks lots and roads (with ExportRoadArea). Detects legal dimension self-intersection.
LRS-8 Lot area exists — shows legal area (from traverse) and geometric area (from polyline) with difference. Warns if areas differ at 4 significant figures. Shows override area if set.
LRS-10 Part lot areas — checks part lots found and reports count
LRS-11 Date of survey exists and is not a future date
LRS-13 Datum terminals A and B assigned (surveyed plans only)
LRS-19 SCIMS mark count meets pre-SSIR2024 requirements based on lot count
LRS-21 Combined scale factor present (surveyed plans only)
LRS-27 Lot numbers sequential, numeric, multipart consistency

R3Survey Rules

Rule Description
R3-META Plan metadata completeness (surveyor, firm, purpose, LGA, parish, county)
R3-DESC Road/Easement/Hydro parcels have descriptions set
R3-PREFIX Parcel name prefixes correct (R for Roads, E for Easements, H for Hydro)
R3-CLOSED All parcels are closed polylines
R3-GEOM No duplicate vertices (zero-length segments) or backtracking legs

Not yet implemented

Rules requiring complex geometry analysis (control traverse loop misclose, datum bearing/distance checks, RM placement rules) and rules requiring SCIMS database access are shown as stubs and will be implemented in future versions.

How it identifies parcels

Parcels are identified by:

  1. XData Class attribute (Lot, Road, Easement, Hydrography, etc.)
  2. XData Type attribute (Road, Easement, Parcel)
  3. Layer name matching against the plan's component layers

Parcels without a Class/Type set and not on a known non-lot layer are treated as lots.

Self-intersection detection

LRS-6 builds a legal traverse from the rounded/overridden dimensions (same as R3LOTEDIT) and checks if any non-adjacent legs cross. This detects:

  • Line-line crossings
  • Line-arc crossings (including major arcs)
  • Arc-arc crossings

Adjacent arc-line pairs are also checked since arcs can bulge past the shared vertex.

Crossings are classified as:

  • Interior — real geometry problem, reported as FAIL
  • Misclose-related — crossing near the start/end junction in long traverses, typically harmless rounding
