Nota: questa descrizione è in parte obsoleta. Con la versione 0.13 e successive l'operazione è analoga, ma la selezione dell'asse avviene diversamente da come descritto in questa pagina. Ora è possibile utilizzare l'asse normale allo schizzo oppure utilizzare uno spigolo dell'oggetto e quindi produrre schiere orientate in qualsiasi direzione espressa con uno spigolo. Anche le finestre dello opzioni hanno un aspetto diverso.

''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.''
</div>


<span id="Usage"></span>
Con i pulsanti di opzione, si può scegliere uno degli assi standard '''X''', '''Y''' o '''Z'''. La direzione della schiera può essere invertita spuntando '''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.

== Ordering features ==
==Options==
When creating a polar pattern feature, the 'polar pattern parameters' dialogue offers two different ways of specifying the pattern rotation axis.
===Normal sketch axis===
An axis being normal to the sketch and starting in the origin of the sketch of the feature being used is taken as axis for the polar pattern.<br />
The pattern direction can be reversed by ticking 'Reverse direction'.
===Select reference===
Here you can select an edge as a reference.<br />
If that option is chosen only the edge of a feature being used just before the polar pattern-operation is choosable.
So you are able to use this option by:
*creating a helper feature (for example a pad) with on of the edges being the axis of the polar pattern
*create feature (pad or pocket) to be patterned
*select polar pattern feature and select edge as reference
*use another helper feature (for example pocket) to remove your first helper feature.
The pattern direction can be reversed by ticking 'Reverse direction'.


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.

<span id="Limitations"></span>
===Angle and Occurrences ===
==Limitazioni==
Specifies the angle to be covered by the pattern, and the total number of pattern shapes (including the original feature). For example, four occurrences in an angle of 180 degrees would give a spacing of 60 degrees between patterns. There is one exception: If the angle is 360 degrees, since first and last occurrence are identical, four occurrences will be spaced 90 degrees apart.


* 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.
===Limitazioni===
* 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|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 [https://forum.freecadweb.org/viewtopic.php?f=3&t=55192 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|PartDesign MultiTransform]].

Serie lineare

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.
