Description

The TechDraw 3PtAngleDimension tool adds an angular dimension to a View. The dimension shows the interior angle between three vertices.

Measuring the angle between three vertices; the second vertex is the apex of the angle

Usage

  1. Select three points. The second point will be the apex of the angle. The geometry may be selected in the 3D view or in the drawing.
  2. If you have selected geometry in the 3D view: add the correct TechDraw View to the selection by selecting it in the Tree view.
  3. There are several ways to invoke the tool:
  4. A dimension is added to the View.
  5. The dimension may be dragged to the desired position.
  6. If needed, add tolerances as described on this page.

See TechDraw LengthDimension.

Change properties

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.

Limitations

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

Properties

See TechDraw LengthDimension.

Scripting

See also: Autogenerated API documentation and FreeCAD Scripting Basics.

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'))]
rc = page.addView(dim1)
