How to view contour lines on *.trm files in Leica iCON Office

1. Double click on your *.trm file to open it, then click on the icon.
   

2. In the TRM Properties untick the show triangles and tick the show contour lines. When you select Equidistance, it sets the spacing for the contour lines. When checking a *.trm it is recommended to use 0.1 or a custom number of 0.05 for flat sites.
   
   Your *.trm file will now display contour lines rather than 3D triangles in the map view.
