Description

The Horizontal Dimension tool adds a horizontal dimension to a View. The dimension may be between two vertices, the length of one edge or the horizontal 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 TechDraw LinkDimension.svg TechDraw LinkDimension tool.

TechDraw Dimension Horizontal example.png

Length dimension taken from two arbitrary nodes of the view; the distance is measured horizontally

Usage

  1. Select the points or edge which define your measurement.
  2. Press the TechDraw HorizontalDimension.svg Horizontal 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 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.

Limitations

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

Properties

Scripting

See also: TechDraw API and FreeCAD Scripting Basics.

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