{{GuiCommand/it
Durante la creazione di una funzione di schiera polare, il dialogo 'Parametri schiera polare' offre due modi diversi per specificare l'asse di rotazione del modello.

<span id="Description"></span>
===Asse normale dello schizzo===
==Descrizione==
Come asse della schiera viene preso un asse essendo perpendicolare al disegno e posto nell'origine del disegno.<br />
La direzione della schiera può essere invertita barrando 'direzione inversa'.


<div class="mw-translate-fuzzy">
===Selezionare un asse di riferimento===
Lo strumento '''Serie polare''' prende una funzione selezionata e ne crea una serie di copie ruotate attorno a un asse prescelto. A partire da v0.17, è in grado di replicare più funzioni.
In questo modo è possibile selezionare uno spigolo come asse di rotazione.<br />
</div>
Con tale opzione è usabile solo il bordo di una funzione utilizzata appena prima dell'operazione polare in atto.
Per utilizzare questa opzione:
*creare una funzione di supporto, per esempio un pad, in cui uno dei bordi possa essere usato come asse della schiera polare
*creare la funzione (pad o tasca) da replicare
*selezionare la funzione schiera polare e selezionare il bordo di riferimento
*utilizzare una nuova funzione di supporto, ad esempio una tasca, per rimuovere la precedente funzione di supporto.
La direzione della schiera può essere invertita barrando 'direzione inversa'.

Specifica l'angolo da coprire con la schiera e il numero totale di forme della schiera (inclusa la forma originale). Per esempio, la combinazione quattro copie in un angolo di 180 gradi produce una spaziatura di 60 gradi tra ogni copia. C'è una eccezione: quando l'angolo è di 360 gradi e la prima e l'ultima copia sono identiche, vengono prodotte quattro copie distanziate 90 gradi.

Descrizione

Lo strumento Serie polare prende una funzione selezionata e ne crea una serie di copie ruotate attorno a un asse prescelto. A partire da v0.17, è in grado di replicare più funzioni.

Sopra: una tasca a forma di slot (B) realizzata sopra un solido di base (A, indicato anche come supporto) viene utilizzata per un modello polare. Il risultato (C) è mostrato a destra.

Utilizzo

Create

  1. Optionally activate the correct Body.
  2. Optionally select one or more features in the Tree view or the 3D view.
  3. There are several ways to invoke the tool:
    • Press the PolarPattern button.
    • Select the Part Design → Apply a pattern → PolarPattern option from the menu.
  4. If there is no active Body, and there are two or more Bodies in the document, the Active Body Required dialog will open and prompt you to activate one. If there is a single Body it will be activated automatically.
  5. If no features were selected the Select feature task panel opens: select one or more (hold down the Ctrl key) from the list and press the OK button.
  6. The PolarPattern parameters task panel opens. See Options for more information.
  7. Press the OK button to finish.

Edit

  1. Do one of the following:
    • Double-click the PolarPattern object in the Tree view.
    • Right-click the PolarPattern object in the Tree view and select Edit PolarPattern from the context menu.
  2. The PolarPattern parameters task panel opens. See Options for more information.
  3. Press the OK button to finish.

Opzioni

  • To add features:
    1. Press the Add feature button.
    2. Select a feature in the Tree view or the 3D view.
    3. Repeat to add more features.
  • To remove features:
    1. Press the Remove feature button.
    2. Do one of the following:
      • Select a feature in the Tree view or the 3D view.
      • Select a feature in the list and press the Del key.
      • Right-click a feature in the list and select Remove from the context menu.
    3. Repeat to remove more features.
  • If there are several features in the pattern, their order can be important. See Ordering features.
  • Specify the Axis of the pattern:
    • Normal sketch axis: The Z axis of the sketch (only available for sketch-based features).
    • Vertical sketch axis: The Y axis of the sketch (idem).
    • Horizontal sketch axis: The X axis of the sketch (idem).
    • Construction line #: A separate entry for each construction line in the sketch (idem).
    • Base X axis: The X axis of the Body.
    • Base Y axis: The Y axis of the Body.
    • Base Z axis: The Z axis of the Body.
    • Select reference...: Select a Datum Line in the Tree view or a Datum Line or edge in the 3D view.
  • Check the Reverse direction checkbox to reverse the pattern.
  • introduced in version 1.0: Specify the angle Mode:
    • Overall Angle: Enter the overall Angle. If the angle is less than 360°, the occurrences are evenly distributed from 0° (first occurrence) to the given angle (last occurrence). If the angle is 360°, the occurrences are evenly distributed around the circle. For n occurrences an angle of 360° is equivalent to an angle of 360°*(1-1/n).
    • introduced in version 1.0: Offset Angle: Enter the Offset angle from a given point on the first occurrence to the same point on the next occurrence. For n occurrences: OverallAngle=(n-1)*Offset.
  • Specify the number of Occurrences (including the original feature).
  • If the Update view checkbox is checked the view will update in real time.

Ordering features

If some of the selected features are additive and others subtractive, their order can have have an impact on the final result. You can change the order by dragging individual features in the list.

Effect of the feature order

Limitazioni

  • Any shape in the pattern that does not overlap the parent feature will be excluded. This ensures that a PartDesign Body always consists of a single, connected solid.
  • The PartDesign patterns are not yet as optimized as their Draft counterparts. So for a large number of instances you should consider using a Draft PolarArray instead, combined with a Part boolean operation. This may require major changes to your model as you are leaving PartDesign and therefore cannot simply continue with further PartDesign features in the same body. An example is shown in this Forum topic.
  • A pattern cannot be applied directly to another pattern, be it polar, linear or a mirror. For this you need a PartDesign MultiTransform.
