EXPGE

The EXPGE export KML files for Google Earth. Use it in conjunction with the READKML

To use the command:

1. call the EXPGE command on the command line
2. You will be asked to select the objects to be exported:
3. The following screen will be displayed:
   In it, you should choose some options, for example:
   • Closed lines are "Polygon" - Closed lines in AutoCAD can be exported as single lines (Path) or closed polygon (Polygon) in Google Earth.
     Basically the difference is that the polygon is populated with the line color in autocad, using transparency at 50%
   • Maintain hatch texture - Hatchings made with AutoCAD standards such as "LINE", "GRAVEL", "DASH" etc will be exported as "Multigeometry" in Google Earth, simulating Hatch pattern.
   • Dimensions: In Google Earth, rows can have relative, absolute, or grounded dimensions. Choose the option you want
   • Coordinates - Your drawing must be in Universal Transverse Mercator (UTM) or Coordinate (latitude / longitude) coordinates with AutoCAD's World Coordinate System (WCS) coordinates
   • Zone / Central Meridian Once the UTM system is green, you must tell which Zone it refers to. If you do not know which fuse to use, know that the earth globe is divided into 60 Zones, each with its central meridian. Therefore, Click the button with the ">" symbol and a world map will be displayed:
     
     
     
     Click on the area of ??your interest. The Zone and the hemisphere will be calculated. Each Zone has its own UTM system.
   • Coordinate reference - Finally, you should choose which one is yours, for example SAD69, WGS84 ... This reference should be configured in the expge.ini file, with the parameters of radius Earth, ellipsoid flattening, and the coordinate transformation vector for the WGS84 system, which is used by Gollge Earth.

4. In Google Earth, exported objects will be grouped into folders whose names match the object's layer.
5. The result will be:
