Define Side View Tool
Use the Define side view tool to define the side view direction.
The Define side view tool is only available if the Top view tool is enabled.
Set the X-Y-position of the left edge of the side view window with the first mouse click and the right edge with the second click. TuMan calculates the zoom factor and displays the new projection of the tunnel axis in the side view window. TuMan also plots a projection of the side view direction in the top view window if the corresponding option in the View Settings dialog is set.
