Описание

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 the TechDraw LinkDimension tool.

Measuring a circle, indicating the radius

Применение

  1. 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)
  2. Press the Radius 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.

Ограничения

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

Свойства

See TechDraw LengthDimension.

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')]
rc = page.addView(dim1)
