Description
The Draft OrthoArray tool creates an orthogonal (3-axes) array from a selected object.
This tool can be used on any object that has a Part TopoShape, meaning 2D shapes created with the Draft Workbench, but also 3D solids created with other workbenches, for example, Part, PartDesign, or Arch. It can also create App Links instead of simple copies.
- To create polar or circular arrays, use the corresponding PolarArray and CircularArray tools.
- To position copies along a path use PathArray or PathLinkArray.
- To position copies at specified points use PointArray or PointLinkArray.
- To create copies and manually place them use Move or Rotate.
- To create exact copies and manually place or scale them, use Clone or Std LinkMake.
This command deprecates the previously existing Array as well as the short lived LinkArray tools.
Orthogonal array from a solid object.
Usage
- Select the object that you wish to duplicate.
- Press the Array button. If no object is selected, you will be invited to select one.
- The task panel is launched, where you can select the number of elements in each X, Y, Z direction; and the interval between each created element.
- You can click on the 3D view to set up all the numbers and intervals, and complete the command. Otherwise, just press Enter or the OK button to complete the operation.
Notes
- 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.
- This command creates the same parametric "Array" object as the one created with the PolarArray and CircularArray tools. Therefore, the array can be converted to orthogonal, polar, or circular by changing its DataArray Type property.
Options
These are the options displayed in the task panel.
- Number of elements: the elements in the X, Y, and Z directions. A copy of the original object is always produced, so this number must be at least
1
in every direction. - X intervals: the values of displacement for the copies in the X direction. To create strictly rectangular arrays, the Y and Z values should be zero
(x, 0, 0)
. - Y intervals: the values of displacement for the copies in the Y direction. To create strictly rectangular arrays, the X and Z values should be zero
(0, y, 0)
. - Z intervals: the values of displacement for the copies in the Z direction. To create strictly rectangular arrays, the X and Y values should be zero
(0, 0, z)
. - Reset X, Y, Z: it resets the interval vectors to a rectangular displacement, that is
(x, 0, 0)
,(0, y, 0)
, and(0, 0, z)
. - Fuse: if it is checked, the resulting objects in the array will fuse together if they touch each other. This only works if Link array is unchecked.
- Link array: if it is checked, the resulting array will be a "Link array". This array internally uses App Link objects, so it is more efficient when handling many copies of complex shapes. However, in this case, the objects cannot be fused together.
- Press Esc or the Cancel button to abort the current command.
Note: if a Link array is created, this object cannot be converted to a regular array. And similarly, a regular array cannot be converted to a Link array. Therefore, you must choose the type of array that you want at creation time.
Properties
See also: Property editor.
The Draft OrthoArray command, the Draft PolarArray command and the Draft CircularArray command create the same object. This object is derived from a 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:
Data
Link
The properties in this group are only available for Link arrays. See Std LinkMake for more information.
- DataScale (
Float
) - Data (Hidden)Scale Vector (
Vector
) - DataScale List (

PlacementList
) - Data (Hidden)Element List (
LinkList
) - Data (Hidden)_ Link Touched (
Bool

) - Data (Hidden)Colored Elements (
LinkSubHidden
) - DataLink Transform (
Bool
)
Circular array
The properties in this group are hidden for Orthogonal arrays and Polar array.
- DataNumber Circles (
Integer
): the number of circular layers to create. The DataBase object counts as one layer; it must be at least1
. - DataRadial Distance (
Distance
): the distance between circular layers. - DataSymmetry (
Integer
): a number that indicates the symmetry lines in the circular layers. This number changes the distribution of the objects and making it very large may eliminate the more central layers. - DataTangential Distance (
Distance
): the distance between copies in the same circular layer.
Objects
- DataArray Type (
Enumeration
): specifies the type of array to create,"ortho"
,"polar"
, or"circular"
. - DataAxis Reference (
LinkGlobal
): specifies the object and edge that can be used as reference for polar and circular arrays; for example, it can be the edge of a Wire or a PartDesign DatumLine. If this property exists, it overrides both DataAxis and DataCenter, for polar and circular arrays. - DataBase (
Link
): specifies the object to duplicate in the array. - DataCount (
Integer
): (only available for Link arrays, read-only) it is the total number of objects in the array including the original object. This property is read-only as the value depends on the other "Number" properties, whether they are orthogonal, polar, or circular. - DataExpand Array (
Bool
): (only available for Link arrays) if it istrue
, the individual App Link objects will be available to select in the tree view. - DataFuse (
Bool
): it defaults tofalse
; if it istrue
, and the copies intersect with each other, they will be fused together into a single shape. This only works if the initial array was not a "Link array".
Orthogonal array
The properties in this group are hidden for Circular arrays and Polar array.
- DataInterval X (
VectorDistance
): a vector specifying the interval between each copy on the X axis. - DataInterval Y (
VectorDistance
): a vector specifying the interval between each copy on the Y axis. - DataInterval Z (
VectorDistance
): a vector specifying the interval between each copy on the Z axis. - DataNumber X (
Integer
): the number of copies on the X direction. The DataBase object counts as one copy; it must be at least1
. - DataNumber Y (
Integer
): the number of copies on the Y direction. - DataNumber Z (
Integer
): the number of copies on the Z direction.
Polar array
The properties in this group are hidden for Circular arrays and Orthogonal array.
- DataAngle (
Angle
): specifies the aperture of the circular arc to cover with copies; use 360 to cover an entire circle. - DataInterval Axis (
VectorDistance
): distance and orientation of each copy in DataAxis direction. - DataNumber Polar (
Integer

The properties in this group are hidden for Orthogonal array.
- DataAxis (
Vector
): the axis direction around which the elements in a polar or circular array are created. - DataCenter (
VectorDistance

Scripting
See also: Autogenerated API documentation and FreeCAD Scripting Basics.
Parametric array
To create a parametric orthogonal array use the make_array
method (introduced in version 0.19) of the Draft module. This method replaces the deprecated makeArray
method. The make_array
method can create Draft OrthoArrays, Draft PolarArrays and Draft CircularArrays. For each array type one or more wrappers are available.
The main method:
array = make_array(base_object, arg1, arg2, arg3, arg4=None, arg5=None, arg6=None, use_link=True)
The wrappers for orthogonal arrays are:
array = make_ortho_array(base_object,
v_x=App.Vector(10, 0, 0), v_y=App.Vector(0, 10, 0), v_z=App.Vector(0, 0, 10),
n_x=2, n_y=2, n_z=1,
use_link=True)
array = make_ortho_array2d(base_object,
v_x=App.Vector(10, 0, 0), v_y=App.Vector(0, 10, 0),
n_x=2, n_y=2,
use_link=True)
The wrappers for rectangular arrays are:
array = make_rect_array(base_object,
d_x=10, d_y=10, d_z=10,
n_x=2, n_y=2, n_z=1,
use_link=True)
array = make_rect_array2d(base_object,
d_x=10, d_y=10,
n_x=2, n_y=2,
use_link=True)
base_object
is the object to be arrayed. It can also be theLabel
(string) of an object in the current document.v_x
,v_y
, andv_z
are the vectors between the base points of the elements in the respective directions.d_x
,d_y
, andd_z
are the distances between the base points of the elements in the respective directions.n_x
,n_y
, andn_z
are the numbers of elements in the respective directions.- If
use_link
isTrue
the created elements are App Links instead of regular copies. array
is returned with the created array object.
Example:
import FreeCAD as App
import Draft
doc = App.newDocument()
rect = Draft.make_rectangle(1500, 500)
v_x = App.Vector(1600, 0, 0)
v_y = App.Vector(0, 600, 0)
array = Draft.make_ortho_array2d(rect, v_x, v_y, 3, 4)
doc.recompute()
Non-parametric array
To create a non-parametric orthogonal array use the array
method of the Draft module. This method returns None
.
array(objectslist, xvector, yvector, xnum, ynum)
array(objectslist, xvector, yvector, zvector, xnum, ynum, znum)
Example:
import FreeCAD as App
import Draft
doc = App.newDocument()
rect = Draft.make_rectangle(1500, 500)
v_x = App.Vector(1600, 0, 0)
v_y = App.Vector(0, 600, 0)
Draft.array(rect, v_x, v_y, 3, 4)
doc.recompute()
