A civil engineer exports a DXF site plan (drawn in UTM Zone 10N) → The tool reprojects it to WGS84 → Google Earth displays the property boundary, building footprints, and utility lines correctly over satellite imagery, with each AutoCAD layer as a toggleable folder.
The Drawing Exchange Format (DXF) is a vector data format developed by Autodesk. It stores geometry (lines, polylines, points) using $X, Y, Z$ coordinates. Crucially, a standard DXF file does not inherently understand "where" on Earth it is located. It treats a drawing as an infinite grid, often using "local" coordinates (e.g., 0,0 to 1000,1000) rather than geospatial coordinates. dxf to kml autocad
