Lot Edit (R3LOTEDIT)

Command: R3LOTEDIT

Opens the Lot Edit form for a selected closed polyline, showing a side-by-side comparison of geometric dimensions (from the polyline) and legal dimensions (rounded per R3Units settings, or overridden).

Usage

  1. Type R3LOTEDIT at the command line
  2. Select a closed polyline
  3. The form opens showing all legs with geometric and legal values
  4. Review the legal area, misclose, and s26(2) compliance check
  5. Click OK to save the calculated legal area as an area override on the polyline

What the form shows

Traverse table

Each row represents one leg of the polyline:

Column Description
Leg Leg number (1, 2, 3...)
Type Line or Arc
Geo Bearing Geometric bearing from polyline coordinates
Geo Dist Geometric distance from polyline coordinates
Geo Radius Geometric radius (arcs only)
Geo Arc Geometric arc length (arcs only)
Legal Bearing Rounded bearing (per R3Units angle rounding) or override
Legal Dist Rounded distance (per R3Units length rounding) or override
Legal Radius Rounded radius or override (arcs only)
Legal Arc Rounded arc length or override (arcs only)
Source "rounded" or "override"

All values are read-only. To set overrides, use the Dimension Overrides expander in R3PROPERTIES.

Double-click to zoom

Double-click any row in the traverse table to zoom to that segment in the drawing. This works correctly even when a UCS is active.

Geometric summary (left panel)

  • Area — from the AutoCAD polyline geometry, in drawing area units
  • Misclose — should be 0.000 (closed polyline)
  • Perimeter — total perimeter in drawing length units
  • Calculated — area computed from legal (rounded/overridden) dimensions
  • Override — the currently stored area override value (if set)
  • Difference — difference between calculated and override
  • Misclose — misclose vector from legal dimension traverse
  • Perimeter — total perimeter from legal dimensions
  • s26(2) check — PASS or FAIL against SSIR s26(2): misclose ≤ 15mm + 100ppm of perimeter

Warnings

The form displays warning banners at the top when issues are detected:

  • Self-intersecting polyline (>500ppm) — geometric area is hidden, legal area suppressed
  • Self-intersecting polyline (minor) — geometric area shown with "(WARNING: self-intersecting polyline)" suffix
  • Legal dimensions self-intersecting — legal area shown with "(WARNING: self-intersecting)" when the rounded/overridden dimensions create a traverse that crosses itself
  • Duplicate vertices — "Zero-length segment(s) detected. Run R3REMOVEDUPVERTS to fix."
  • Backtracking — "Backtracking at vertex N — segment returns over previous segment."
  • The s26(2) check shows green for PASS, red for FAIL
  1. Bearings — geometric bearing rounded to the nearest value set in R3Units angle rounding (e.g. nearest 5 seconds)
  2. Distances — geometric distance rounded per R3Units length rounding settings (e.g. nearest 5mm)
  3. Overrides — if a dimension override is set on a leg via R3PROPERTIES, that value is used instead of rounding

NSW Land Registry Services requires that the area stated on a plan matches the area calculated from the plan's legal dimensions (the rounded bearings and distances shown on the plan). Because rounding introduces small changes, the legal area differs slightly from the exact polyline area. The R3LOTEDIT form lets you see and verify this difference.

On OK

When you click OK, the calculated legal area is saved as an Area Override on the polyline. This override value is used during NSW LandXML export instead of the polyline's geometric area.
