Фиксирует горизонтальное расстояние между 2 точками или концами отрезка. Если выбрана только одна точка, расстояние устанавливается в точки центра координат эскиза.

Continue mode

  1. Make sure there is no selection.
  2. There are several ways to invoke the tool:
    • introduced in version 1.0: If the Dimensioning constraints preference is set to Single tool (default): press the down arrow to the right of the button and select the Constrain horizontal distance option from the dropdown.
    • If this preference has a different value (and in version 0.21 and below): press the Constrain horizontal distance button.
    • Select the Sketch → Sketcher constraints → Constrain horizontal distance option from the menu.
    • introduced in version 1.0: Right-click in the 3D view and select the Dimension → Constrain horizontal distance option from the context menu.
    • Use the keyboard shortcut: L.
  3. The cursor changes to a cross with the tool icon.
  4. Do one of the following:
    • Select two points (one of which can be the origin).
    • Select a single line.
  5. If a driving dimensional constraint is created, depending on the preferences, a dialog opens to edit its value.
  6. A constraint is added.
  7. Optionally keep creating constraints.
  8. To finish, right-click or press Esc, or start another geometry or constraint creation tool.

Run-once mode

  1. Do one of the following:
    • Select one or two points.
    • Select a single line.
  2. Invoke the tool as explained above.
  3. Optionally edit the constraint value.
  4. A constraint is added.


Расстояние от начала координат:

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

Расстояние между двумя вершинами:

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.
