If applicable please consider using the [[Constraint_HorizontalDistance|Horizontal Distance]] or [[Constraint_VerticalDistance|Vertical Distance]] constraints instead. These constraints are more robust and faster to calculate than the here documented length constraint.

====Operation====
==Description==
Select a line in the sketch,<br />
[[File:LengthConstraint1.png|256px]]<br />
by clicking on the line (it turns dark green).<br />
[[File:LengthConstraint2.png|256px]]<br />
Apply the Length Constraint by selecting the icon [[File:Constraint_Length.png|16px]] from the Sketcher Constraints toolbar or selecting the Constrain distance menu item from the Sketcher Constraints sub-menu of the Sketcher menu item in the Sketcher workbench (or Part Design in the Part Design workbench).<br />
[[File:LengthConstraint3.png|256px]]<br />
The length of the line is constrained to its current value.Double clicking on the constraint in the 3D view or in the Tasks tab of the Combo View will bring up a dialog box to allow the constraint value to be edited.<br />
[[File:LengthConstraint4.png|256px]]<br />
Enter the required value and click OK to set the constraint length.<br />
[[File:LengthConstraint5.png|256px]]<br />
The Length Constraint also constrains the distance between a line and a point.<br />
[[File:LengthConstraint6.png|256px]]<br />
Select the line and a point in the sketch,<br />
[[File:LengthConstraint7.png|256px]]<br />
then apply the constraint as before.<br />
The perpendicular distance between the point and the line is constrained to its current value. this may be edited as described above to set the constraint to a desired value.<br />
[[File:LengthConstraint8.png|256px]]<br />
The constraint may also be applied to two points, selected here at either end of a poly-line.<br />
[[File:LengthConstraint9.png|256px]]<br />
Applying the constraint as before, the distance between the two selected points is constrained. As described above it may be edited to set a desired value.<br />

== Scripting ==

Distance from origin:

{{Code|code=Sketch.addConstraint(Sketcher.Constraint('Distance', Edge, PointOfEdge, -1, 1, App.Units.Quantity('123.0 mm')))}}

Distance between two vertices:

{{Code|code=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):

{{Code|code=Sketch.addConstraint(Sketcher.Constraint('Distance', Line, 1, Line, 2, App.Units.Quantity('123.0 mm')))}}

Distance from point ({{incode|Edge, PointOfEdge}}) to perpendicular point on line ({{incode|Line}}):

{{Code|code=Sketch.addConstraint(Sketcher.Constraint('Distance', Edge, PointOfEdge, Line, 0, App.Units.Quantity('123.0 mm')))}}

Distance between the edges of two circles:

{{Code|code=Sketch.addConstraint(Sketcher.Constraint('Distance', Circle1, 0, Circle2, 0, App.Units.Quantity('123.0 mm')))}}

The [[Sketcher_scripting|Sketcher scripting]] page explains the values which can be used for {{incode|Edge}}, {{incode|Edge1}}, {{incode|Edge2}}, {{incode|PointOfEdge}}, {{incode|PointOfEdge1}}, {{incode|PointOfEdge2}}, {{incode|Line}}, {{incode|Circle1}} and {{incode|Circle2}}, and contains further examples on how to create constraints from Python scripts.

Descripción

La Restricción de Distancia restringe la longitud de una línea, la distancia perpendicular entre un punto y una línea o la distancia entre dos puntos a un valor específico.

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 distance option from the dropdown.
    • If this preference has a different value (and in version 0.21 and below): press the Constrain distance button.
    • Select the Sketch → Sketcher constraints → Constrain distance option from the menu.
    • introduced in version 1.0: Right-click in the 3D view and select the Dimension → Constrain distance option from the context menu.
    • Use the keyboard shortcut K then D.
  3. The cursor changes to a cross with the tool icon.
  4. Do one of the following:
    • Select a single line.
    • Select two points.
    • Select a point and a line (in that order).
  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 a single line.
    • Select two points.
    • Select a point and a line (in any order).
    • Select the edges of two circles or arcs.
    • Select the edge of a circle or arc and a line (idem).
    • introduced in version 1.0: Select the edge of a single arc.
  2. Invoke the tool as explained above.
  3. Optionally edit the constraint value.
  4. A constraint is added.

Notes

Scripting

Distance from origin:

Sketch.addConstraint(Sketcher.Constraint('Distance', Edge, PointOfEdge, -1, 1, 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 perpendicular point on line (Line):

Sketch.addConstraint(Sketcher.Constraint('Distance', Edge, PointOfEdge, Line, 0, App.Units.Quantity('123.0 mm')))

Distance between the edges of two circles:

Sketch.addConstraint(Sketcher.Constraint('Distance', Circle1, 0, Circle2, 0, App.Units.Quantity('123.0 mm')))

The Sketcher scripting page explains the values which can be used for Edge, Edge1, Edge2, PointOfEdge, PointOfEdge1, PointOfEdge2, Line, Circle1 and Circle2, and contains further examples on how to create constraints from Python scripts.
