Am trying to insert image from google to the excat coordinate of my draw via CAD-earth. There was an option allow me to get image inside polygon kml. So i create a hatch are in civil 3d and export it to kml. But the quadrilateral geometry some how turn into a triangle. This doesnt make sense at all, pls help!

Export KML has issues with certain types of objects, hatching is probably one of them. Just make simple lines and export those, it will work fine. Then you can create your polygon in Google Earth.

Hi @nam.lethai1995

Bà Rịa–Vũng Tàu, correct?

You have an 'Auto-Registered' custom coordinate system. Can you explain HOW your created your coordinate system? The method you used to create it is affecting the way your KML is exported.

I can't find your coordinate system in the coordinate system library.

Enter MAPCSLIBRARY on command line and search for your custom CS. On my end, I can't find it in the library.

If you created it properly, you can get Lat/Long coordinates. You should also be able to turn on Bing Aerial imagery. You can't do either in your dwg.

Hi @nam.lethai1995,
Opening your drawing adds the VN-2000-3d-107d45 coordinate system and VN-2000-Datum to my MAPCSLIBRARY, but that Datum lacks a Geodetic Transformation to WGS84.
