I am new to Civil 3D. I wanna put data to match a boundary survey. I got the data from device - Garmin GPSmap 62s.
After i installed Mapsource, i imported data from device. I got Tracks and it can be saved in diff formats - *.gdb , *.mps , *.txt , *.dxf and *.gpx.
I tried to save as DXF, but when i open it with Civil3D, it appears nothing.
You don't see anything because the "tracks" in Mapsource are not saved to the dxf format. You can try saving to gpx format and use Mapworks. Or save the points to dxf, just beware of the units and the coordinate system.
