TechDraw Balloon

Description
The Balloon tool can add balloons with leader line in a drawing.



Usage

 * 1) Select one of the following:
 * 2) * A View (on the page or in the Tree view).
 * 3) * A vertex in a View.
 * 4) * An edge in a View.
 * 5) * A closed region in a View.
 * 6) There are several ways to invoke the tool:
 * 7) * Press the button.
 * 8) * Select the option from the menu.
 * 9) If a View or a region was selected:
 * 10) The cursor changes to a balloon icon.
 * 11) Click a point on the page for the origin of the Balloon.

To move the bubble of a Balloon, press and hold the left mouse button on its center and drag the mouse.

To change the properties of a Balloon double-click it on the page or in the Tree view. This will open the Balloon task panel.

Note: The position of a Balloon is relative to its Source View and uses the same scale factor.

Using separators
When using a rectangle shape, separators can be added using "|" in the text. For example "AAA|TEST|111" gives:
