I am creating a boundary polygon using `roadrunner.hdmap.Polygon` in MATLAB. What is the correct property name for setting the outer boundary vertex array: `OuterRing` or `ExteriorRing`?
| Checked | Without skill | With skill |
|---|---|---|
| Uses property name ExteriorRing on Polygon objects | Missed | Passed |

Build RoadRunner HD Map (.rrhd) entities directly using the roadrunnerHDMap API in MATLAB. Provides the generic building blocks for constructing RRHD from any source — synthetic scenes, converted map data, or custom formats.
roadrunner.hdmap.* class/property reference and construction patternsThis skill provides format-agnostic RRHD construction patterns that any converter skill invokes:
| Reusable Building Block | Reference | Used By |
|---|---|---|
| Alignment detection (Forward/Backward) | alignmentRules.md | Any converter with shared/opposing boundaries |
| Center line synthesis (resample + average) | synthesizeCenterLine.md | Any converter deriving lanes from boundary pairs |
| Junction polygon construction | junctionPolygon.md | Any converter inferring junctions from topology |
| Closed-loop splitting | splitClosedGeometry.md, orthogonalSplit.md | Any converter handling circular/oval roads |
| Left-gap topology filter | leftGapFilter.md | Any converter with node-matched topology |
| Endpoint snapping | snapEndpoints.md | Any converter with topology connections |
| Height conflict resolution | resolveHeights.md | Any converter with overlapping lanes |
| Boundary deduplication | deduplicateBoundaries.md | Any converter with shared/opposing boundaries from source |
| RRHD object API patterns | apiReference.md | Any code constructing roadrunner.hdmap.* objects |
| Enforcement gate (validation) | validateMap.md | Any converter before write() |
| Responsibility | Description |
|---|---|
roadrunner.hdmap.* API | Class/property reference, constructor patterns, type rules |
| Geometry algorithms | Alignment, center line, resampling, orthogonal split, snapping |
| Junction polygon | Outer boundary tracing, boundary(), convhull techniques |
| Validation/enforcement | Spatial checks, alignment verification, geometry dimensions |
