* All Dimensions are extremely vulnerable to the infamous "topological naming" issue. It is not possible at this time to keep references to 2D (projected) or 3D (actual) geometrical objects in sync with changes in the model. It is recommended that Dimensions be added towards the end of the drawing creation process.

TechDraw Dimension Diameter

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

  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 Dimension Radius button
  3. A dimension will be added to the View. The dimension may be dragged to the desired position.

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)
