The PathArray tool can be used on any object that has a [[Part_TopoShape|Part TopoShape]], meaning 2D shapes created with the [[Draft_Workbench|Draft Workbench]], but also 3D solids created with other workbenches, for example, [[Part_Workbench|Part]], [[PartDesign_Workbench|PartDesign]], or [[Arch_Workbench|Arch]].
Both commands can be used on 2D objects created with the [[Draft_Workbench|Draft Workbench]] or [[Sketcher_Workbench|Sketcher Workbench]], but also on many 3D objects such as those created with the [[Part_Workbench|Part Workbench]], [[PartDesign_Workbench|PartDesign Workbench]] or [[Arch_Workbench|Arch Workbench]].

==Alignment==
Each element in the array is an exact clone of the original object, but the entire array is considered a single unit in terms of properties and appearance.


The alignment of the elements in a Draft PathArray depends on the properties of the array and the orientation of the source object. The position of the source object is ignored: for the purpose of the array the {{Value|x}}, {{Value|y}} and {{Value|z}} are set to {{Value|0}}. If the {{PropertyData|Align}} property of the array is set to {{FALSE}} the orientation of the array elements is identical to that of the source object. If it is set to {{TRUE}} the X axis of the local coordinate system of each element placement is tangent to the path. The Y and Z axes of the local coordinate systems depend on the {{PropertyData|Align Mode}} property of the array. Other array properties involved in the alignment include {{PropertyData|Tangent Vector}}, {{PropertyData|Force Vertical}} and {{PropertyData|Vertical Vector}}.
{{Emphasis|Note:}} if the {{PropertyData|Base}} object doesn't seem to be positioned correctly in the path, check that its {{PropertyData|Placement}} is in the origin {{Value|(0,0,0)}}. Certain objects can be placed anywhere in the 3D space when used with the {{Button|[[Image:Draft_PathArray.svg|16px]] [[Draft_PathArray|PathArray]]}} tool, but others must be at the origin, particularly those created by using {{Button|[[File:Part_Extrude.svg|16px]] [[Part_Extrude|Part Extrude]]}} with a 2D profile like a {{Button|[[File:Sketcher_NewSketch.svg|16px]] [[Sketch|Sketch]]}}.

===Align Mode===

Three modes are available:

====Original====

This mode comes closest to the single {{PropertyData|Align Mode}} available in version 0.18. It relies on a fixed normal vector. If the path is planar this vector is perpendicular to the plane of the path, else a default vector, the positive Z axis, is used. From this normal vector and the local tangent vector (the local X axis) a [https://en.wikipedia.org/wiki/Cross_product cross product] is calculated. This new vector is used as the local Z axis. The orientation of the local Y axis is determined from the local X and Z axes.

====Frenet====

This mode uses the local normal vector derived from the path at each element placement. If this vector cannot be determined (for example in the case of a straight segment) a default vector, again the positive Z axis, is used instead. With this vector and the local tangent vector the local coordinate system is determined using the same procedure as in the previous paragraph.

====Tangent====

This mode is similar to {{PropertyData|Align Mode}} {{Value|Original}} but includes the possibility to pre-rotate the source object by specifying a {{PropertyData|Tangent Vector}}.

===Force Vertical and Vertical Vector===

These properties are only available if {{PropertyData|Align Mode}} is {{Value|Original}} or {{Value|Tangent}}. If {{PropertyData|Force Vertical}} is set to {{TRUE}} the local coordinate system is calculated in a different manner. The {{PropertyData|Vertical Vector}} is used as a fixed normal vector. From this normal vector and the local tangent vector (the local X axis) again a cross product is calculated. But now this vector is used as the local Y axis. The orientation of the local Z axis is determined from the local X and Y axes.

Using these properties can be required if one of the edged of the path is (almost) parallel to the default normal of the path.

A [[Draft_PathArray|PathArray]] is derived from a [[Part_Feature|Part Feature]] ({{incode|Part::Feature}} class), therefore it shares all the latter's properties. In addition to the properties described in [[Part_Feature|Part Feature]], the PathArray has the following properties in the [[property_editor|property editor]].

A Draft PathArray object is derived from a [[Part_Feature|Part Feature]] object and inherits all its properties (with the exception of some View properties that are not inherited by Link arrays). The following properties are additional unless otherwise stated:

==Additional alignment modes and options introduced in v0.19==

'''Original''' mode (the default) is the historic alignment mode as in version 0.18.
It is not really the Frenet alignment. Original mode uses the normal parameter
from Draft.getNormal (or the default) as a constant - it does not calculate
curve normal. X follows the curve tangent, Y is the normal parameter, Z is
X.Cross(Y).

'''Tangent''' mode is similar to '''Original''', but includes a rotation to align the
Base object's X to the TangentVector before placing copies. After the
rotation, Tangent behaves the same as Original. In previous versions this
rotation would be performed manually before invoking PathArray.

'''Frenet''' mode orients the copies to a coordinate system along the path. X is
tangent to curve, Y is curve normal, Z is curve binormal. If a normal can not
be computed (ex a straight line), the default is used.

The ForceVertical option applies to Original and Tangent modes. When this
option is applied, the normal parameter from Draft.getNormal is ignored. X
follows the curve tangent, Z is the VerticalVector property and Y is
X.Cross(Z).

Descriere

Instrumentul PathArray plasează copii ale unei forme selectate de-a lungul unei căi selectate. Calea poate fi un Filament sau una sau mai multe muchii. Formele pot fi opțional aliniate cu tangenta traiectoriei. Dacă este necesar, poate fi specificat un Vector de tranlație pentru a deplasa formele astfel încât centroidul să fie pe traiectorie. Dacă nu sunt selectate obiecte, veți fi invitat să le selectați.

Both commands can be used on 2D objects created with the Draft Workbench or Sketcher Workbench, but also on many 3D objects such as those created with the Part Workbench, PartDesign Workbench or Arch Workbench.

Draft PathArray

Cum se folosește

  1. Creați un obiect tip formă pe care doriți să îl distribuiți/multiplicați. Veți obține cele mai bune rezultate dacă obiectul dvs. este centrat în jurul originii, chiar dacă calea începe în altă parte.
  2. Selectați un obiect tip traiectorie de-a lungul căruia vor fi distribuite formele. -sau-
  3. Selectați unele margini ale unui obiect traiectorie.
  4. Apasați pe butonul Draft PathArray.

Alignment

The alignment of the elements in a Draft PathArray depends on the properties of the array and the orientation of the source object. The position of the source object is ignored: for the purpose of the array the x, y and z are set to 0. If the DateAlign property of the array is set to false the orientation of the array elements is identical to that of the source object. If it is set to true the X axis of the local coordinate system of each element placement is tangent to the path. The Y and Z axes of the local coordinate systems depend on the DateAlign Mode property of the array. Other array properties involved in the alignment include DateTangent Vector, DateForce Vertical and DateVertical Vector.

3 arrays based on the same non-planar path. From left to right: Align is false, Align is true with Align Mode Original and Align is true with Align Mode Frenet

.

Align Mode

Three modes are available:

Original

This mode comes closest to the single DateAlign Mode available in version 0.18. It relies on a fixed normal vector. If the path is planar this vector is perpendicular to the plane of the path, else a default vector, the positive Z axis, is used. From this normal vector and the local tangent vector (the local X axis) a cross product is calculated. This new vector is used as the local Z axis. The orientation of the local Y axis is determined from the local X and Z axes.

Frenet

This mode uses the local normal vector derived from the path at each element placement. If this vector cannot be determined (for example in the case of a straight segment) a default vector, again the positive Z axis, is used instead. With this vector and the local tangent vector the local coordinate system is determined using the same procedure as in the previous paragraph.

Tangent

This mode is similar to DateAlign Mode Original but includes the possibility to pre-rotate the source object by specifying a DateTangent Vector.

Force Vertical and Vertical Vector

These properties are only available if DateAlign Mode is Original or Tangent. If DateForce Vertical is set to true the local coordinate system is calculated in a different manner. The DateVertical Vector is used as a fixed normal vector. From this normal vector and the local tangent vector (the local X axis) again a cross product is calculated. But now this vector is used as the local Y axis. The orientation of the local Z axis is determined from the local X and Y axes.

Using these properties can be required if one of the edged of the path is (almost) parallel to the default normal of the path.

                             use_link=True)
  • Plasează un numpr de copii ale unui obiect tip formă al documentului de-a lungul unui obiect tip traiectorie sau sub-obiecte ale unui path-object. Opțional translatează fiecare copie prin FreeCAD.Vector xlate pe direcția și la distanța pentru a ajusta pentru diferența de formă centru vs punct de referință. Opțional, aliniază elementul de bază la calea tangentă/normală/binormală.
