Description
The Dimension Radius tool adds a radius dimension to a View. The dimension may be applied to any Edge in the drawing which is a circle or circular arc. The distance will initially be the projected distance (ie as shown on the drawing), but this may be changed to the actual 3D distance using the 
Link Dimension tool.
Measuring a circle, indicating the radius
Usage
- Select a circle or circular arc in the drawing. (Note some arcs which appear to be circular are actually ellipses or BSplines. You cannot make a radius dimension in these cases)
- Press the
Dimension Radius button - A dimension will be added to the View. The dimension may be dragged to the desired position.
- If needed, add tolerances as described in this page.
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.
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 Radius 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 = "Radius"
dim1.References2D=[(view1, 'Edge1')]
rc = page.addView(dim1)
