Descrizione
Fissa una distanza orizzontale tra due punti. È applicabile tra tutti i punti dello schizzo. Quando viene selezionato un solo punto la distanza è riferita all'origine.
Utilizzo
- Selezionare due punti o una linea
- Richiamare il comando in uno di questi modi:
- Cliccare sull'icona
Distanza orizzontale della barra degli strumenti. - Usare la scorciatoia da tastiera Maiusc + H.
- Usare la voce Sketch → Vincoli → Distanza orizzontale dal menu principale.
- Cliccare sull'icona
- Si apre una finestra di dialogo per modificare o confermare il valore. Premere OK per confermare.
Nota: lo strumento di vincolo può essere avviato anche senza selezione precedente, ma richiede la selezione di due punti o una linea. Per impostare la distanza dall'origine, è necessario selezionare anche il punto di origine dello schizzo. Di default il comando è in modalità continua per creare nuovi vincoli; per uscire dal comando premere il tasto destro del mouse o una volta il tasto ESC.
Scripting
Distance from origin:
Sketch.addConstraint(Sketcher.Constraint('DistanceX', Edge, PointOfEdge, 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 Edge1, Edge2, Edge, PointOfEdge1, PointOfEdge2, PointOfEdge and Line, and contains further examples on how to create constraints from Python scripts.
