Vazba Délka nastavuje délku přímky, kolmou vzdálenost mezi bodem a přímkou nebo vzdálenost mezi dvěma body.

Sketcher ConstrainDistance example.png


  1. Pick two points or one line or one point and one line.
  2. Invoke the command several ways:
    • Press the Sketcher ConstrainDistance.svg Constrain distance button in the Sketcher toolbar.
    • Use the Shift + D keyboard shortcut. (D is for Distance)
    • Use the Sketch → Sketcher constraints → Sketcher ConstrainDistance.svg Constrain 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. To set the perpendicular distance between a point and a line, the point needs to be selected first. 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.



Pokud uvažujete o její aplikaci, zamyslete se raději nad použitím vazeb Horizontální vzdálenost nebo vertikální vzdálenost. Tyto vazby jsou robustnější a mají rychlejší výpočet než zde popisovaná vazba Délka.


Distance from origin:

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

Distance between two vertices:

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

Length 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('Distance', Line, 1, Line, 2, App.Units.Quantity('123.0 mm')))

Distance from point (Edge, PointOfEdge) to nearest point on line (Line):

Sketch.addConstraint(Sketcher.Constraint('Distance', Edge, PointOfEdge, Line, App.Units.Quantity('123.0 mm')))

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