Description
The Balloon tool adds a ...

Balloon ...
How to use
- Select the View to which the Balloon will be attached...
- Press the
Balloon button - A balloon will be added to the View. The balloon bubble may be dragged to the desired position. Use CTL-drag to move the bubble and the arrow.
Limitations
Dimension objects are vulnerable to "topological naming" issues. This means that if you modify the 3D geometry the faces and edges of the model may be renamed internally; if a dimension is attached to an edge that is then modified, the dimension may break. In general, it is not possible to keep the projected 2D dimensions synchronized with the actual 3D objects.
Therefore, it is recommended that dimensions be added when the 3D model is no longer being modified.
Properties
Data
- DATAX: Horizontal position of the balloon bubble relative to the View.
- DATAY: Vertical position of the balloon bubble relative to the View.
View
- VIEWFont: The name of the font to use for the balloon bubble.
- VIEWFontsize: Dimension text size in mm.
Scripting
See also: TechDraw API and FreeCAD Scripting Basics.
The Balloon tool can be used in macros and from the Python console by using the following functions:
bal1 = FreeCAD.ActiveDocument.addObject('TechDraw::DrawViewBalloon','Balloon')
rc = page.addView(bal1)
