Descriere
Attachment este un utilitar pentru asocierea unui obiect cu altul. Obiectul asociat este legat de celălalt obiect, ceea ce înseamnă că dacă poziționarea acestuia este modificată ulterior, obiectul asociat se actualizează în noua sa poziție.
Attacher engines
The attachment of an object is controlled by one of four attacher engines. The default engine that is used for an object depends on its type. An object's attacher engine can be changed via its DateAttacher Engine property (introduced in 1.0) or its hidden DateAttacher Type property.
The available engines are listed in the table below. Attacher engines control the DatePlacement of objects. All engines can be used for all objects that have this property. But the results of the last three make the most sense if the shape of the object matches the mentioned 'Logical Shape'.
| Attacher Engine | Attacher Type | Logical Shape |
|---|---|---|
| Engine 3D | Attacher::AttachEngine3D | |
| Engine Plane | Attacher::AttachEnginePlane | Planar face coincident with the XY plane of the Placement |
| Engine Line | Attacher::AttachEngineLine | Straight edge collinear with the Z axis of the Placement |
| Engine Point | Attacher::AttachEnginePoint | Vertex coincident with the origin of the Placement |
The rest of this page focuses on the Engine 3D. The modes of the other engines are only listed. Note that the modes of Engine Plane are in fact identical to those of Engine 3D.
Cum se foloseste
- Selectați obiectul de atașat.
- Mergeți la meniul Part → Attachment....
- Notă: Atunci când se lucrează în PartDesign pentru a crea schițe, geometrie de referință sau primitive, etapele 1 și 2 nu sunt necesare: caseta de dialog Atașamentul este activat automat.
- Mai jos, în parametrii Attachment, Not attached poate fi citit. Primul buton de jos este etichetat Selecting… pentru a indica că se așteaptă o selecție în vizualizarea 3D .
- Selectați un element topologic pe obiectul care urmează să fie asociat: un vârf, o margine, o fațetă sau un plan. De asemenea, pot fi selectate geometrii de referință ale unei piese Part containers .
- Eticheta primului buton adoptă acum tipul de topologie selectat. În câmpul alb spre dreapta, se adaugă obiectul de referință și elementul său de referință. De exemplu, dacă o fațetă este selectată pe o primitivă tip cub, câmpul arată Box:Face6.
- Selectați un Attachment mode din listă. Modurile disponibile sunt filtrate prin referințele selectate. Sub titlul Attached with mode <mode description> este afișat sub antetul/headerul Attachment.
- Pentru informații în timp real despre modul de asociere, plasați cursorul mouse-ului peste unul dintre modurile în listă pentru a afișa un indiciu.
- Opțional, adăugați până la 3 referințe apăsând butoanele Reference2, Reference3, și Reference4 și repetând pasul 4.
- Optional deefiniți un Attachment Offset.
- Apăsați OK.

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.
If no vertex is linked the DateMap Path Parameter property determines the point. The object's origin is translated to the vertex if the vertex is first, or kept at the curve if the curve is first.
Frenet NBT is similar to Z tangent to edge, except that the X axis is well-defined.

- Curve, Vertex
- Vertex, Curve
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.
See Frenet NBT.
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.
See Frenet NBT.
Concentric
Aligns to plane to osculating circle of an edge. Optional Vertex link defines where .

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 .
- Roll: rotates the attached object along the reference object's X axis .
- Pitch: rotates the attached object along the reference object's Y axis .
- Yaw: rotates the attached object along the reference object's Z axis .
- Flip sides: if checked, the attached object is reversed from its XY plane .
