Descrizione
L'utilità Convalida lo schizzo può essere usata per riparare uno schizzo che non è più modificabile, cha ha vincoli non validi, o per aggiungere vincoli di coincidenza a uno schizzo creato da una geometria importata come file DXF. Può anche essere utile individuare una coincidenza mancante in uno schizzo nativo che genera un errore "can't validate broken face" quando si tenta di applicare una funzione di PartDesign.
Utilizzo
- Selezionare lo schizzo da convalidare, dall'albero del modello o facendo clic su uno dei suoi bordi nella vista 3D. Nota: lo schizzo non deve essere in modalità di modifica. Se si è in modalità di modifica dello schizzo, è necessario usire dallo schizzo.
- Aprire l'utility di convalida dal menu Schizzo o Part Design.
- Selezionare le sottostanto opzioni per l'operazione.
- Premere il pulsante Chiudi quando fatto.
Opzioni
Missing coincidences
Finds out missing coincidences for overlapping vertices, and adds them. Press the Find button; a pop up dialog will appear to report how many missing coincidences were found; they will be shown in the 3D view as yellow crosses. Press OK to close the dialog, then press the Fix button to add the missing coincidences.
If necessary, define a larger tolerance value in the drop-down field.
Leave the "Ignore construction geometry" checkbox checked to disregard construction geometry in the analysis.
