Description

The Dimension Angle3Pt 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 angle using the TechDraw Dimension Link.svg Link Dimension tool.

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


How to use

  1. Select the points or edge which define your measurement.
  2. Press the TechDraw Dimension Angle3Pt.png Dimension Angle3Pt button
  3. A dimension will be added to the View. The dimension may be dragged to the desired position.

Limitations

Dimension objects are vulnerable to "topological naming" issues. See the information in the TechDraw Dimension Length tool for more information.

Properties

This object has the same properties as the TechDraw Dimension Length tool. See that tool for details.

Scripting

See also: TechDraw API and FreeCAD Scripting Basics.

The Dimension Angle3Pt 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'))]
rc = page.addView(dim1)
