Descrizione
Lo strumento 
Toggle Constraint commuta i vincoli dimensionali (blocco, distanza orizzontale o verticale, lunghezza, raggio e angolo) in modalità di riferimento e viceversa. Le icone nella barra degli strumenti diventano blu e, al posto dei vincoli dimensionali, vengono create delle quote di riferimento. Le quote di riferimento non vincolano lo schizzo. Può essere utile creare quote di riferimento in uno schizzo come modo per verificare le misurazioni; quando gli viene assegnato un nome, possono essere utilizzate anche per guidare i vincoli in un altro schizzo attraverso le espressioni.
Contrary to driving constraints, reference constraints do not constrain the sketch, their value depends on other constraints, they are driven. They can be useful to verify measurements. They can be used in expressions, but not in the sketch itself.
Per definire il profilo sono stati impostati un vincolo di distanza orizzontale (50 mm), un vincolo verticale (30 mm) e un vincolo di angolo (75°); poi al segmento inclinato è stata aggiunta una quota di riferimento per conoscerne la sua lunghezza (31,0583 mm).
Utilizzo
Toggle tools
- Premere il pulsante
Vincoli guida o definitivi. Le icone di vincoli dimensionali nella barra degli strumenti Vincoli di Sketcher passano da rosso a blu. - Funziona come la creazione di vincoli dimensionali, sempre nello stesso modo, ma ora viene invece aggiunta una quota di riferimento di colore blu.
- Per riportare la barra degli strumenti Vincoli dello Sketcher alla modalità vincolo (rosso), premere nuovamente il pulsante Vincoli guida o definitivi.
- Per trasformare un vincolo dimensionale in una quota di riferimento, o il contrario, selezionarlo e premere il pulsante Vincoli guida o definitivi.
Toggle constraints
- Select one or more dimensional constraints.
- Invoke the tool as described above, or with one of the following additional options:
- introduced in version 0.22: Right-click in the 3D view and select the
Toggle driving/reference constraint option from the context menu. - Right-click in the Constraints section of the Sketcher Dialog and select the Toggle to/from reference option from the context menu.
- introduced in version 0.22: Right-click in the 3D view and select the
- The selected constraints are changed from driving to reference mode or vice versa. Their appearance changes accordingly.
- The mode of the dimensional constraint creation tools is not changed.
