The [[Image:Draft_PathArray.svg|24px]] '''Draft PathArray''' command creates a regular array from a selected object by placing copies along a path. Use the [[Draft_PathLinkArray|Draft PathLinkArray]] command to create a more efficient [[App_Link|Link]] array instead. Except for the type of array that is created, Link array or regular array, the [[Draft_PathLinkArray|Draft PathLinkArray]] command is identical to this command. |
||
Both commands can be used on 2D objects created with the [[Draft_Module|Draft Workbench]] or [[Sketcher_Workbench|Sketcher Workbench]], but also on many 3D objects such as those created with the [[Part_Module|Part Workbench]], [[PartDesign_Workbench|PartDesign Workbench]] or [[Arch_Module|Arch Workbench]]. |

* To create orthogonal, polar or circular arrays, use the corresponding {{Button|[[File:Draft_OrthoArray.svg|16px]] [[Draft_OrthoArray|OrthoArray]]}}, {{Button|[[File:Draft_PolarArray.svg|16px]] [[Draft_PolarArray|PolarArray]]}}, or {{Button|[[File:Draft_CircularArray.svg|16px]] [[Draft_CircularArray|CircularArray]]}} tools. |
|||
* To position [[App_Link|App Link]] copies along a path use {{Button|[[File:Draft_PathLinkArray.svg|16px]] [[Draft_PathLinkArray|PathLinkArray]]}}. |

* To position copies at specified points use {{Button|[[File:Draft_PointArray.svg|16px]] [[Draft_PointArray|PointArray]]}} or {{Button|[[File:Draft_PointLinkArray.svg|16px]] [[Draft_PointLinkArray|PointLinkArray]]}}. |
|||
* To create copies and manually place them use {{Button|[[File:Draft_Move.svg|16px]] [[Draft_Move|Move]]}} or {{Button|[[File:Draft_Rotate.svg|16px]] [[Draft_Rotate|Rotate]]}}. |

==Usage== |
==Usage== |
||
# Select the object |
# Select the object you wish to array. |
||
# |
# Add the path object to the selection. It is also possible to select edges instead. The edges must belong to the same object, they must be connected, and they must be selected in the correct order. |
||
# There are several ways to invoke the command: |
|||
# Press the {{Button|[[Image:Draft_PathArray.svg|16px]] [[Draft_PathArray|PathArray]]}} button. |
|||
#* Press the {{Button|[[Image:Draft_PathArray.svg|16px]] [[Draft_PathArray|Draft PathArray]]}} button. |
|||
# The Array object is immediately created. You must change the properties of the array to change the number and direction of copies created. |
|||
#* Select the {{MenuCommand|Modification → Array tools → [[Image:Draft_PathArray.svg|16px]] Path array}} option from the menu. |
|||
# The array is created. |
|||
# Optionally change the [[#Properties|properties]] of the array in the [[property_editor|Property editor]]. |
|||
==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 position and orientation of the subelements of the source object, relative to its local coordinates system. The {{PropertyData|Placement}} of the source object is ignored. If the {{PropertyData|Align}} property of the array is set to {{FALSE}} the orientation of the array elements is identical to that of the original subelements. 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]]}}. |

==Options== |

{{Caption|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=== |
|||
There are no options for this tool. Either it works with the selected objects or not. |
|||
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: |

==Technical explanation for the Align property== |
|||
When {{PropertyData|Align}} is {{FALSE}}, the placement of the copied shapes is easy to understand; they are just moved to a different position in their original orientation. |

|||
{{clear}} |
|||
{{Caption|Object arranged along a closed path in the original orientation}} |
|||
When {{PropertyData|Align}} is {{TRUE}}, the positioning of the shapes becomes a bit more complex: |
|||
# First, Frenet coordinate systems are built on the path: X is tangent, Z is normal, Y is binormal. |
|||
# Then the original object is copied to every on-path coordinate system, so that the global origin is matched with the on-path coordinate system origin. |

As you reorient the path but not the object, the result is consistent: the object remains aligned to the path the way it was before reorienting the path. |
|||
{{Emphasis|Editor:}} thank you to user DeepSOIC for this explanation. |
|||
==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). |

Draft Array |
Description
The Draft PathArray command creates a regular array from a selected object by placing copies along a path. Use the Draft PathLinkArray command to create a more efficient Link array instead. Except for the type of array that is created, Link array or regular array, the Draft PathLinkArray command is identical to this command.
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
Usage
- Select the object you wish to array.
- Add the path object to the selection. It is also possible to select edges instead. The edges must belong to the same object, they must be connected, and they must be selected in the correct order.
- There are several ways to invoke the command:
- Press the Draft PathArray button.
- Select the Modification → Array tools → Path array option from the menu.
- The array is created.
- Optionally change the properties of the array in the Property editor.
Alignment
The alignment of the elements in a Draft PathArray depends on the properties of the array, and the position and orientation of the subelements of the source object, relative to its local coordinates system. The VeriPlacement of the source object is ignored. If the VeriAlign property of the array is set to false
the orientation of the array elements is identical to that of the original subelements. 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 VeriAlign Mode property of the array. Other array properties involved in the alignment include VeriTangent Vector, VeriForce Vertical and VeriVertical 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 VeriAlign 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 VeriAlign Mode Original
but includes the possibility to pre-rotate the source object by specifying a VeriTangent Vector.
Force Vertical and Vertical Vector
These properties are only available if VeriAlign Mode is Original
or Tangent
. If VeriForce Vertical is set to true
the local coordinate system is calculated in a different manner. The VeriVertical 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.

Scripting
See also: Autogenerated API documentation and FreeCAD Scripting Basics.
To create a path array use the make_path_array
method (introduced in version 0.19) of the Draft module. This method replaces the deprecated makePathArray
method.
path_array = make_path_array(base_object, path_object,
count=4, extra=App.Vector(0, 0, 0), subelements=None,
align=False, align_mode="Original", tan_vector=App.Vector(1, 0, 0),
force_vertical=False, vertical_vector=App.Vector(0, 0, 1),
use_link=True)
base_object
is the object to be arrayed. It can also be theLabel
(string) of an object in the current document.path_object
is the path object. It can also be theLabel
(string) of an object in the current document.count
is the number of elements in the array.extra
is a vector that displaces each element.subelements
is a list of edges ofpath_object
, for example["Edge1", "Edge2"]
. If supplied only these edges are used for the path.- If
align
isTrue
the elements are aligned along the path depending on the value ofalign_mode
, which can be"Original"
,"Frenet"
or"Tangent"
. tan_vector
is a unit vector that defines the local tangent direction of the elements along the path. It is used whenalign_mode
is"Tangent"
.- If
force_vertical
isTrue
vertical_vector
is used for the local Z direction of the elements along the path. It is used whenalign_mode
is"Original"
or"Tangent"
. - If
use_link
isTrue
the created elements are App Links instead of regular copies. path_array
is returned with the created array object.
Example:
import FreeCAD as App
import Draft
doc = App.newDocument()
p1 = App.Vector(500, -1000, 0)
p2 = App.Vector(1500, 1000, 0)
p3 = App.Vector(3000, 500, 0)
p4 = App.Vector(4500, 100, 0)
spline = Draft.make_bspline([p1, p2, p3, p4])
obj = Draft.make_polygon(3, 500)
path_array = Draft.make_path_array(obj, spline, 6)
doc.recompute()
wire = Draft.make_wire([p1, -p2, -p3, -p4])
path_array2 = Draft.make_path_array(obj, wire, count=3, extra=App.Vector(0, -500, 0), subelements=["Edge2", "Edge3"], align=True, force_vertical=True)
doc.recompute()
