Border drawing
When Border M ode is activated, Draw tools are selected by default and displayed at the bottom of the Toolbar. Border drawing is currently only active on surface structures in Montage, All, or Surface views.

- 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.

- When done drawing borders, remember to save changes using Save/Manage Files.
