Click Relative on the Select Point menu. SURFCAM displays the World dialog box and prompt you to "Enter the 'relative' values."
Select Cartesian or Polar coordinates. Enter the relative Cartesian or Polar coordinate values into the dialog box, and then click OK.
SURFCAM will display a modified Select Point menu and prompt you to "Pick the relative point."
Use the appropriate command from the modified Select Point menu to pick the relative point. SURFCAM will then measure from this location using the relative coordinates to find the new location and mark it with a small square.
