Descrizione

Lo strumento Sketcher Vincolo raggio fissa il raggio di cerchi, archi e Cerchi di peso B-spline.

Utilizzo

Modalità continua

1. Assicurarsi che non ci sia alcuna selezione.
2. Esistono diversi modi per richiamare lo strumento:
   • disponibile dalla versione 1.0: Se la preferenza Vincoli dimensionali è impostata su Strumento singolo (predefinito): premere la freccia giù a destra del pulsante e selezionare il pulsante {{MenuCommand|[[Image:Sketcher_ConstrainRadius.svg|16px] ] Vincolo raggio}} dal menu a discesa.
   • Se questa preferenza ha un valore diverso (e in versione 0.21 e precedenti): premere il pulsante Vincolo raggio.
   • Selezionare l'opzione Schizzo → Vincoli Sketcher → Vincolo raggio dal menu.
   • disponibile dalla versione 1.0: fare clic con il pulsante destro del mouse nella 3D view e selezionare l'opzione Dimensione → Vincolo raggio dall'elenco menu contestuale.
   • Usare la scorciatoia da tastiera: K quindi R.
3. Per ulteriori passaggi vedere Sketcher Vincolo raggio/diametro.

Script

Sketch.addConstraint(Sketcher.Constraint('Radius', ArcOrCircle, App.Units.Quantity('123.0 mm')))

La pagina Sketcher scripting spiega i valori che possono essere utilizzati per ArcOrCircle e contiene ulteriori esempi su come creare vincoli da script Python.
