Polygon

Polygon represents arbitrary closed shapes extracted from the drawing. It contains ordered vertex coordinates, optional arc segments, and unit metadata so you can reconstruct the outline faithfully. Polygons are used for redaction zones, inspection areas, or complex profiles that do not fit simple primitives. By storing them in a consistent format, the API enables spatial analysis like area calculations, overlap detection, or highlighting regions in visualization tools. The model also records which view or annotation produced the polygon to maintain traceability and captures confidence scores that indicate when manual validation may be beneficial. You can even combine polygons with measurement data to derive surface areas for quoting.
