  1. Enable the Edit Mode of the radar plugin by setting the editmode attribute to true:
    <plugin name="radar"
  2. Right-click the radar and select "Radar Plugin - Edit Heading":
  3. Now you can drag the radar to adjust the heading, find the heading where the pano view and the radar are showing the same view. There will be a red crosshair in the pano and a red line in the radar for helping finding the same point. The current heading and addtional information about the current xml or scene will be shown on the screen:
  4. When done end the edit mode by right-click the radar again: The heading value will be copied into the system clipboard.
