## Описание

The 3-Point Angle Dimension tool adds a angular dimension to a View. The dimension may be specified by selecting three Vertices on a View. Note that the second of the three Vertices is the apex of the angle. The Angle3Pt will initially be the projected angle (ie as shown on the drawing), but this may be changed to the actual 3D distance using the tool.

Measuring the angle between two straight lines using three vertices; the second vertex should be the apex of the angle

## Применение

1. Select the points or edge which define your measurement.
2. Press the button
3. A dimension will be added to the View. The dimension may be dragged to the desired position.

To change the properties of a dimension object either double-clicking it in the drawing or in the Tree view. This will open the dimension dialog.

## Ограничения

Dimension objects are vulnerable to the "topological naming problem". See TechDraw LengthDimension for more information.

The 3-Point Angle Dimension tool can be used in macros and from the Python console by using the following functions:

```dim1 = FreeCAD.ActiveDocument.addObject('TechDraw::DrawViewDimension','Dimension')
dim1.Type = "Angle3Pt"
dim1.References2D=[(view1, 'Vertex1',(view1, 'Vertex4'),(view1, 'Vertex2'))]
