Description

The Dimension Length tool adds a linear dimension to a View. The dimension may be between the distance between two vertices, the length of one edge or the distance between 2 edges. 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.

How to use

  1. Select the points or edge which define your measurement.
  2. Press the File:TechDraw Dimension Length.png Dimension Length button
  3. A dimension will be added to the View. The dimension may be dragged to the desired position.

Options

None.

Properties

Template:TechDraw DimProps

Scripting

See also: TechDraw API and FreeCAD Scripting Basics.

The Dimension Length 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 = "Distance"
dim1.References2D=[(view1, 'Edge1')]
rc = page.addView(dim1)

Notes

  • 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.
