Descripción

The Dimension Diameter tool adds a diameter dimension to a View. The dimension may be applied to any circular in the drawing. 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 diameter

Utilización

  1. Select a circular edge in the drawing. (Note some arcs which appear to be circular are actually ellipses or BSplines. You cannot make a diameter dimension in these cases)
  2. Press the Dimension Diameter 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 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.

Limitaciones

Dimension objects are vulnerable to "topological naming" issues. See the information in the TechDraw Dimension Length tool for more information.

Propiedades

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 Diameter 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 = "Diameter"
dim1.References2D=[(view1, 'Edge1')]
rc = page.addView(dim1)
