Description
Descrizione
Il vincolo Distanza impone alla lunghezza di una linea, alla distanza perpendicolare tra un punto e una linea o alla distanza tra due punti di assumere un valore specifico.
Utilizzo
See also: Drawing aids.
Continue mode
- Selezionare due punti o una linea
- Richiamare il comando in uno di questi modi:
- Cliccare sull'icona
Distanza della barra degli strumenti. - Usare la scorciatoia da tastiera Maiusc + D.
- Usare la voce Sketch → Vincoli → Distanza dal menu principale.
- Cliccare sull'icona
- Si apre una finestra di dialogo per modificare o confermare il valore. Premere OK per confermare.
Run-once mode
- 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.
- Invoke the tool as explained above.
- Optionally edit the constraint value.
- A constraint is added.
Notes
Suggerimento
Quando sono applicabili conviene usare il vincolo 
Distanza Orizzontale o il vincolo 
Distanza Verticale. Questi vincoli sono più robusti e più veloci da calcolare rispetto al vincolo di Lunghezza documentato qui.
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.
