Mitesh,
Sorry for the late reply here. I trust that you've already figured this out but it's likely due to your map workspace being in a project coordinate system versus geographic. If you want the lat/long/h, you would need to ensure that your TerraFlex Map workspace is in Lat Long geographic. Also, just this week, Trimble added a X, Y, and Z auto field that will populate as an attribute so that you can see your coordinates on a feature in the field. Also, it will show up upon export to shapefile and GDB versus only with CSV.
