Descrizione

Questa macro crea un'elica attorno a un oggetto solido qualunque sia la sua forma, l'elica segue l'intera superficie dell'oggetto. (Python2 è richiesto)

Utilizzo

Seleziona l'oggetto (solido), la macro calcola per valore predefinito:

• Il valore dell'altezza del BoundBox dell'oggetto, il valore X del centro del BoundBox, il valore Y del centro del BoundBox e il valore Z della base del BoundBox.

Configurazione:

• Pas : Il tono dell'elica (Difetto: 1)
• Height : L'altezza dell'elica. Difetto, l'altezza è l'altezza massima del boundBox dell'oggetto.
• Precision : Numero di punti per un giro dell'oggetto, massimo 360 (Difetto: 36)

Coordinate Begin:

• X : Il valore X. Se l'oggetto è sfalsato, il valore dell'asse centrale X BoundBox viene rilevato e utilizzato per difetto.
• Y : Il valore Y. Se l'oggetto è sfalsato, il valore dell'asse centrale Y BoundBox viene rilevato e utilizzato per difetto.
• Z : Il valore Z. La Z della base del BoundBox viene rilevata e utilizzata per impostazione predefinita.

Options:

• BSpline : Viene creata un'elica Bspline.
• Wire : Viene creato un Wire per elica.
• Points : Viene creato un punto in tutte le coordinate create per la creazione di Bspline o Wire.
• Reverse : L'elica è invertita (Difetto: antiorario).
• Se è selezionato si può vedere la progressione nella vista 3D.

Command:

• Quit : Chiude FCSpring_On_Surface
• Ok : Lancia la creazione
