A. Plan/Profile Displays. This part of the page displays a plan and profile view of the cave. Superimposed on these views of the cave are six lines. These lines correspond to Top, Bottom, West, East, North and South limits of of our selection. Any part of the cave that is inside of these limits will be selected.
Dragging The Limit Lines. You can reposition any of these lines by moving the mouse cursor over the line and dragging the line to a new position. You can also use the edit boxes to the right of the display to set the limit lines to an exact position. You can either enter the numbers directly or use the arrow-buttons to increment or decrement the values.
Zooming. The Display are fairly small and it may be difficult to see exactly which parts of the cave you are selecting. For this reason, you can zoom in and magnify the image of the cave by clicking on the “Plus” button at the bottom of the page. You can also zoom out by clicking the “Minus” button. Finally, you can restore the un-magnified view, by clicking on the “Reset” button.
