The Angle Dimension tool adds a angular dimension to a View. The dimension may be the interior angle between any two straight line edges. The angle will initially be the projected angle (ie as shown on the drawing), but this may be changed to the actual 3D distance using the TechDraw LinkDimension.svg TechDraw LinkDimension tool.

Measuring the angle between two straight lines


  1. Select the points or edge which define your measurement.
  2. Press the TechDraw AngleDimension.svg Angle Dimension button
  3. A dimension will be added to the View. The dimension may be dragged to the desired position.
  4. If needed, add tolerances as described on this page.

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


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


See TechDraw LengthDimension.

The 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 = "Angle"
dim1.References2D=[(view1, 'Edge1')]
rc = page.addView(dim1)
