Описание
Прикрепить - это утилита для прикрепления объекта к другому объекту. Прикрепленный объект связан с другим объектом, что означает, что если впоследствии расположение базового объекта будет изменено, то положение прикрепленного объекта тоже обновится до нового положения.

Attach engines
The attachment of an object is controlled by one of four attach engines. The default engine that is used for an object depends on its type.

The four engines are:
 * Attacher::AttachEnginePoint
 * Attacher::AttachEngineLine
 * Attacher::AttachEnginePlane
 * Attacher::AttachEngine3D

The rest of this page focuses on the AttachEngine3D. The modes of the other engines are only listed. Note that the modes of AttachEnginePlane are in fact identical to those of AttachEngine3D.

Применение

 * 1) Select the object to be attached.
 * 2) Select the  option from the menu.
 * 3) The  task panel opens.
 * 4) At the top of the task panel Not attached can be read. The first button labeled  is highlighted to indicate a selection in the 3D view is expected.
 * 5) Select a vertex, edge or face/plane belonging to another object.
 * 6) In the input field to the right of the button, the referenced object and subelement are shown. For example, if a face of a Part Box is selected, the field may show.
 * 7) The available modes are filtered based on the selected references and their order. For example, for modes Align O-Z-X to Align O-Y-X the first reference must be a vertex. If the first reference is a subelement of a different type, they are removed from the list.
 * 8) Select an Attachment mode in the list. For information on the attachment modes, hover the mouse over them for a tooltip to appear.
 * 9) Attached with mode  is now displayed at the top of the task panel.
 * 10) Depending on the selected  mode, add up to three more references by pressing the, , and  buttons and repeating step 5. It is also possible to specify all references before selecting an attachment mode.
 * 11) When selecting an additional reference the label of the previous button will change and display the type of subelement of that reference.
 * 12) Optionally set an Attachment Offset.
 * 13) Press.
 * 14) If applicable, optionally change the  property in the Property editor.

Change attach engine
It is possible to manually change the attach engine of an object:
 * 1) Select the object.
 * 2) Right-click in the Property editor and select  from the context menu.
 * 3) Edit the  property of the object.

Deactivated
Attachment is disabled. The object can be moved by editing its Placement property.

Translate origin
The origin is matched with a vertex. The orientation is still controlled by the Placement property of the attached object.


 * Reference combinations:
 * Vertex.

Object's X Y Z
The Placement is made equal to the Placement of a linked object.


 * Reference combinations:
 * Any
 * Conic

Object's X Z Y
The X, Y and Z axes are matched with a linked object's local X, Z and -Y axes, respectively.


 * Reference combinations:
 * Any
 * Conic

Object's Y Z X
The X, Y and Z axes are matched with a linked object's local Y, Z and X axes, respectively.


 * Reference combinations:
 * Any
 * Conic

XY on plane
The XY plane is aligned to coincide with a planar face.


 * Reference combinations:
 * Plane

XY tangent to surface
The XY plane is made tangent to a face at a vertex.


 * Reference combinations:
 * Face, Vertex
 * Vertex, Face

Z tangent to edge
The Z axis is aligned to be tangent to an edge. An optional vertex defines where.

If no vertex is linked the property determines the point.


 * Reference combinations:
 * Edge
 * Edge, Vertex
 * Vertex, Edge

Frenet NBT


The X and Y axes are aligned to the normal (N) and binormal (B) axes of the Frenet-Serret coordinate system at a point on a curved edge. An optional vertex defines where.

If no vertex is linked the 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.


 * Reference combinations:
 * Curve
 * Curve, Vertex
 * Vertex, Curve

Frenet TNB


The X and Y axes are aligned to the tangent (T) and normal (N) axes of the Frenet-Serret coordinate system at a point on a curved edge. An optional vertex defines where.

See Frenet NBT.

Frenet TBN


The X and Y axes are aligned to the tangent (T) and binormal (B) axes of the Frenet-Serret coordinate system at a point on a curved edge. An optional vertex defines where.

See Frenet NBT.

Concentric
The XY plane is aligned to the osculating circle at a point on an edge. An optional vertex defines where.

If no vertex is linked the property determines the point.


 * Reference combinations:
 * Curve
 * Circle
 * Curve, Vertex
 * Circle, Vertex
 * Vertex, Curve
 * Vertex, Circle

Revolution Section
The Y axis is aligned to match the axis of the osculating circle at a point on an edge. An optional vertex defines where.

See Concentric.

XY plane by 3 points
The XY plane is aligned to pass through three vertices. The X axis will pass through the first two vertices.

Folding


This is a special mode for folding polyhedra. Select four lines that share a common point in this order: contour line (1), fold line (2), other fold line (3), other contour line (4). To determine the coordinate system the selected contour lines are made coincident by rotating line 1 around line 2, and line 4 around line 3. The origin is matched with the common point, the X axis is matched with line 2, the Y axis is aligned towards the direction of the coincident contour lines.


 * Reference combinations
 * Line, Line, Line, Line

Inertia CS
The X, Y and Z axes are matched with those of an inertial coordinate system, constructed on principal axes of inertia and center of mass.


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

Align O-Z-X

Attachment offset
Attachment Offset becomes active when an attachment mode other than Deactivated has been selected. It is used to apply a linear or rotary offset within the attachment coordinate system (ACS), as defined by the attachment mode and the referenced object(s).


 * In x-direction: sets an offset distance along the X axis of the ACS.


 * In y-direction: sets an offset distance along the Y axis of the ACS.


 * In z-direction: sets an offset distance along the Z axis of the ACS.


 * Around x-axis: rotates the attached object around the X axis of the ACS.


 * Around y-axis: rotates the attached object around the Y axis of the ACS.


 * Around z-axis: rotates the attached object around the Z axis of the ACS.


 * Flip sides: if checked, the attachment is reversed. This is equivalent to rotating the object 180° around the Y axis of the ACS.

Ограничения

 * If selecting two lines results in an error: "Points are collinear. Can't make a plane", try selecting three vertices instead.
