|TechDraw → Dimensions → Insert Radius Dimension|
|Introduced in version|
The Radius Dimension 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 thetool.
Measuring a circle, indicating the radius
- 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 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.
dim1 = FreeCAD.ActiveDocument.addObject('TechDraw::DrawViewDimension','Dimension') dim1.Type = "Radius" dim1.References2D=[(view1, 'Edge1')] rc = page.addView(dim1)
