New York Long Island (NAD83(2011), ftUS) uses Lambert Conformal Conic on NAD83(2011) with US survey feet. The zone definition is bundled into the app so the projection runs offline without calling a coordinate service.

For production work, confirm the target CRS, localization control, elevation, and geoid separation before exporting. FieldToCAD keeps preliminary CRS targets blocked from production export.
