Description

The Dimension Horizontal 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 Link Dimension tool.

How to use

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

Options

None.

Properties

  • ДанныеX: Horizontal position of the dimension text relative to the View.
  • ДанныеY: Vertical position of the dimension text relative to the View.
  • ДанныеFont: The name of the font to use for the dimension text.
  • ДанныеFontsize: Dimension text size in mm.
  • ДанныеFormatSpec: Allows additional text to be added to the dimension text. Dimension value will replace %value%.
  • ДанныеLineWidth: Dimension line weight.
  • ДанныеType: Length,radius,diameter, etc. Not normally manipulated by the end user.
  • ДанныеMeasureType: "True" - based on 3D geometry or "Projected" - based on the drawing. Not normally manipulated directly by the end user.

Scripting

Horizonatal dimensions can be added to Pages using Python.

dim1 = FreeCAD.ActiveDocument.addObject('TechDraw::DrawViewDimension','Dimension')
dim1.Type = "DistanceX"
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.
