Part Attachment/it

Descrizione
Attachment è un'utilità per associare un oggetto a un altro. L'oggetto associato è collegato all'altro oggetto, il che significa che se in seguito il posizionamento di quest'ultimo viene modificato, l'oggetto associato si aggiorna alla sua nuova posizione.

Utilizzo

 * 1) Selezionare l'oggetto da associare.
 * 2) Andare al menu Part → Attachment....
 * Nota: quando si lavora in PartDesign per creare schizzi, geometria di riferimento o primitive, i passaggi 1 e 2 non sono necessari: il dialogo Attachment si attiva automaticamente.
 * 1) Sotto i parametri Attachment, può essere letto Not attached. Il primo pulsante sotto è etichettato  per indicare che si aspetta una selezione nella vista 3D.
 * 2) Selezionare un elemento di topologia sull'oggetto da collegare a un: vertice, bordo o faccia o piano. Sono anche selezionabili le geometrie di riferimento da un contenitore Part.
 * 3) L'etichetta del primo pulsante ora adotta il tipo di topologia selezionata. Nel campo bianco alla sua destra, vengono aggiunti l'oggetto di riferimento e il suo elemento. Ad esempio, se viene selezionata una faccia su un cubo primitivo, il campo mostra Box:Face6.
 * 4) Selezionare una modalità di Attachment nella lista. Le modalità disponibili sono filtrate dai riferimenti selezionati. Sotto al titolo Attachment viene visualizzato Attached with mode .
 * Per informazioni in tempo reale sulle modalità di Attachment, posizionare il puntatore del mouse su una delle modalità nell'elenco per visualizzare un suggerimento.
 * 1) Facoltativamente, aggiungere altri 3 ulteriori riferimenti premendo i pulsanti, , e  e ripetere il passo 4.
 * 2) Opzionalmente impostare un Attachment Offset.
 * 3) Premere.

 * Plane

Tangent to surface
Plane is made tangent to surface at vertex.

Frenet NB
Plane is set to normal-binormal (NB) axes of Frenet-Serret coordinates at the point of the edge's curve that is closest to the vertex (or defined by MapPathParameter property, if vertex is not linked). The object's origin is translated to the vertex if the vertex is first, or kept at the curve if edge is first. This mode is similar to Normal to edge, except that X axis is well-defined.

 * Curve
 * Curve, Vertex
 * Vertex, Curve
 * Attacher mode FrenetNB.png

Frenet TN
Plane is set to tangent-normal (TN) axes of Frenet-Serret coordinates at the point of the edge's curve that is closest to the vertex (or defined by MapPathParameter property, if vertex is not linked). The origin of sketch is translated to the vertex if the vertex is first, or kept at the curve if edge is first. Effectively, if the curve is planar, the sketching plane is the plane of the curve.


 * Reference combinations:

 * Curve, Vertex
 * Vertex, Curve

Frenet TB
Plane is set tangent-binormal (TB) axes of Frenet-Serret coordinates at the point of the edge's curve that is closest to the vertex (or defined by MapPathParameter property, if vertex is not linked). The origin of sketch is translated to the vertex if the vertex is first, or kept at the curve if edge is first.

 * Reference combinations:
 * Any
 * Any, Any
 * Any, Any, Any
 * Any, Any, Any, Any

Attachment Offset
Attachment Offset is used to apply a linear or rotary offset from the referenced object. It becomes active when an attachment mode other than Deactivated has been selected.


 * X: sets an offset distance in the X axis of the reference object.


 * Y: sets an offset distance in the Y axis of the reference object.


 * Z: sets an offset distance in the Z axis of the reference object.


 * Yaw: rotates the attached object along the reference object's Z axis.


 * Pitch: rotates the attached object along the reference object's Y axis.


 * Roll: rotates the attached object along the reference object's X axis.


 * Flip sides: if checked, the attached object is reversed from its XY plane.

Limitations

 * Part and Body containers are not supported. While it's possible to use Attachment to align them, the attachment won't be parametrically linked.
