Description

The Sketcher ConstrainDistanceX tool fixes the horizontal distance between 2 points or line ends. If only one point is selected, the distance is set to the sketch origin.

Usage

  1. Pick one or two points or one line.
  2. There are several ways to invoke the command:
    • Press the Constrain horizontal distance button.
    • Select the Sketch → Sketcher constraints → Constrain horizontal distance option from the menu.
    • introduced in version 0.22: Right-click in the 3D view and select the Dimension → Constrain horizontal distance option from the context menu.
    • Use the keyboard shortcut: L.
  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.

Scripting

Distance from origin:

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

Distance between two vertices:

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

Horizontal 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('DistanceX', 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.
