Hi Minko, thanks for the data. I can confirm now that a profile is shown. So, I suggest to change the description for the option from --show-profiles=1 Sets a flag in tdb file which marks set mapset as having contour lines and allows showing profile in MapSource. Default is 0 which means disabled. to --show-profiles=1 Sets a flag in tdb file which enables profile calculation in MapSource or Basecamp based on contour lines. If DEM data (see "Hill Shading (DEM) options") is available the flag changes the status line to show the height when you hover over an area with valid DEM data. OK?
