Using Earth to DXF

Pick the output coordinate system, and the zone for State Plane.
For surface coordinates, set the scaling and combined factor.
Drop a KML or KMZ saved from Google Earth, or choose one. Check the shape counts, then download the DXF or the points CSV.

What is read

Every Placemark's Point, LineString, Polygon outer boundary, standalone LinearRing and gx:Track, named from the placemark. Polygon holes, styles and folders are not carried over. A KMZ is read from its doc.kml, or the first .kml inside.

Output CRS

State Plane: NAD83 grid in US survey feet, with KML altitude converted from metres to feet. The DXF is tagged with the zone's ftUS EPSG code where one exists. WGS84: longitude as X and latitude as Y in degrees. Web Mercator: EPSG:3857 metres.

Coordinate scaling

State Plane only. Leave at No scaling for grid. Grid → Surface divides N and E by the combined factor (grid ÷ surface); Surface → Grid multiplies. Scaling is about 0,0 and the factor must be between 0.95 and 1.05.

DXF layers

POINTS    3  POINT
LINES     4  LWPOLYLINE
POLYGONS  1  LWPOLYLINE
LABELS    2  TEXT

Layer colours are ACI: 3 green, 4 cyan, 1 red, 2 yellow. Polygons are closed polylines; labels carry the placemark name. AC1015 (AutoCAD 2000) with the full table set. Opens in Civil 3D, AutoCAD and MicroStation.

Points CSV

PNEZD, one row per point vertex, numbered from 1, with the placemark name as the description. Only offered when the file has points.

Datum

KML is WGS84. For State Plane it is treated as NAD83, about 1 m apart. Fine for mapping and planning; not for boundary or control work.
