Fixes the vertical distance between 2 points or line ends. If only one point is selected, the distance is set to the sketch origin.

  1. Pick one or two points or one line.
  2. Invoke the command several ways:
    • Press the Sketcher ConstrainDistanceY.svg Constrain vertical distance button.
    • Use the I keyboard shortcut.
    • Use the Sketch → Sketcher constraints → Sketcher ConstrainDistanceY.svg Constrain vertical distance entry from the top menu.
  3. A pop up dialog opens to edit or confirm the value. Press OK to validate.

Note: the constraint tool can also be started with no prior selection, but will require selection of two points or one line. To set the distance to the origin, the sketch origin point needs to be selected as well. By default the command will be in continue mode to create new constraints; press the right mouse button or Esc once to quit the command.


Distance from origin:

Sketch.addConstraint(Sketcher.Constraint('DistanceY', Edge, PointOfEdge, -1, 1, App.Units.Quantity('123.0 mm')))

Distance between two vertices:

Sketch.addConstraint(Sketcher.Constraint('DistanceY', Edge1, PointOfEdge1, Edge2, PointOfEdge2, App.Units.Quantity('123.0 mm')))

Vertical span of line (the GUI allows selecting the edge itself, but it is just a shorthand for using the two extremities of the same line):

Sketch.addConstraint(Sketcher.Constraint('DistanceY', Line, 1, Line, 2, App.Units.Quantity('123.0 mm')))

The Sketcher scripting page explains the values which can be used for Edge, Edge1, Edge2, PointOfEdge, PointOfEdge1, PointOfEdge2 and Line, and contains further examples on how to create constraints from Python scripts.
