The Draft FlipDimension command rotates the dimension text of selected Draft Dimensions 180° around the dimension line. It can be used to correct dimensions whose text appears mirrored. The command does not work properly for angular dimensions.


  1. Select one or more Draft Dimensions.
  2. There are several ways to invoke the command:
    • Press the Flip dimension button.
    • Select the Modification → Flip dimension option from the menu.


  • Draft Dimensions also have a DataFlip Text property. When set to true the text is rotated 180° around the normal direction. This can be combined with the effect of this command.

To flip a Draft Dimension invert its Normal property.


import FreeCAD as App
import Draft

doc = App.newDocument()

p1 = App.Vector(0, 0, 0)
p2 = App.Vector(1000, 0, 0)
p3 = App.Vector(500, 300, 0)
dimension = Draft.make_dimension(p1, p2, p3)
dimension.ViewObject.FontSize = 200

dimension.Normal = dimension.Normal.negative()
