Descripción
La herramienta Dimensión Radio añade una dimensión de radio a una Vista. La dimensión puede aplicarse a cualquier Borde del dibujo que sea un círculo o un arco circular. La distancia será inicialmente la distancia proyectada (es decir, como se muestra en el dibujo), pero puede cambiarse a la distancia real en 3D usando el 
Enlace Dimensión herramienta.
Measuring a circle, indicating the radius
Utilización
- Select a circle or circular arc. The geometry may be selected in the 3D View or in the drawing. Note some arcs which appear to be circular are actually ellipses or B-splines. You cannot make a radius dimension in these cases.
- If you have selected geometry in the 3D View: add the correct TechDraw View to the selection by selecting it in the Tree View.
- There are several ways to invoke the tool:
- introduced in 1.0: If the Dimensioning tools preference is set to
Single tool(default): press the down arrow to the right of the
button and select the 
Radius Dimension option from the dropdown. - If this preference has a different value (and in 0.21 and below): press the Radius Dimension button.
- Select the TechDraw → Dimensions → Radius Dimension option from the menu.
- introduced in 1.0: If the Dimensioning tools preference is set to
- A dimension is added to the View.
- The dimension may be dragged to the desired position.
- If needed, add tolerances as described on this page.

The Radius 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 = "Radius"
dim1.References2D=[(view1, "Edge1")]
page.addView(dim1)
