Drawing a border:
- By default, any loaded border files are
automatically displayed on the surface. To turn borders off
before drawing a new border, toggle off Display Borders
in the Features
Toolbox Borders tab.
- Draw by holding down the alt/option
key and the left mouse button while dragging the mouse.
Red border points will appear where the border is drawn.
- Draw a single, continuous line or draw multiple short sections
or points (all need to be drawn in the same direction).
- The Undo
button removes the last section drawn, the Reset
button erases all the drawing that has not been
saved/finished.
- Mouse and key strokes used to draw a new
border, or erase, extend, or replace a border already drawn
are available as Tooltips.
- When done drawing the border, click the Finish
button and a popup box will appear to save and classify the
new border in a new or an existing loaded border file.

- A Name must be created for each
border (click Add/Edit button), the color may be set with the
sliders or RGB code, the default is black.
- A Class for the border may be
similarly set, otherwise the default is '???'.
- If you click the Closed Border
checkbox, the first and last border point will be joined.
- The finished border will change from red
to the border color set and the new border file and class will
show up in the Features Toolbox. The start point and end point
of the border are marked as green points on the border for
reference.
