Draft OrthoArray

Description

The Draft OrthoArray command creates an orthogonal (3-axes) array from a selected object. The command can optionally create a Link array, which is more efficient than a regular array.

The command 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 BIM Workbench.

Usage

1. Optionally select one object.
2. There are several ways to invoke the command:
   • Press the Array button.
   • Draft: Select the Modification → Array tools → Array option from the menu.
   • BIM: Select the Modify → Array option from the menu.
3. The Orthogonal array task panel opens. See Options for more information.
4. If you have not yet selected an object: select one object.
5. Enter the required parameters in the task panel.
6. To finish the command do one of the following:
   • Click in the 3D view.
   • Press Enter.
   • Press the OK button.

Options

• Enter the Number of elements for the X, Y and Z directions. This number must be at least {{Value|1}} for every direction.
• Enter the X intervals to specify the displacement for the elements in the X direction. For a rectangular array the Y and Z values must be {{Value|0}}.
• Enter the Y intervals to specify the displacement for the elements in the Y direction. For a rectangular array the X and Z values must be {{Value|0}}.
• Enter the Z intervals to specify the displacement for the elements in the Z direction. For a rectangular array the X and Y values must be {{Value|0}}.
• Press the Reset X, Y or Z button to reset the displacement in the given direction to the default values.
• If the Fuse checkbox is checked overlapping elements in the array are fused. This does not work for Link arrays.
• If the Link array checkbox is checked a Link array instead of a regular array is created. A Link array is more efficient because its elements are App Link objects.
• Press Esc or the Cancel button to abort the command.

Notes

• A Draft OrthoArray can be turned into a Draft PolarArray or a Draft CircularArray by changing its Array Type property.
• A Link array cannot be turned into a regular array or vice versa. The type of array must be decided 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:

Scripting

See also: Autogenerated API documentation and FreeCAD Scripting Basics.

Parametric array

To create a parametric orthogonal array use the make_array method ((v0.19) ) 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_objectis the object to be arrayed. It can also be the Label (string) of an object in the current document.

• v_x, v_y, and v_z are the vectors between the base points of the elements in the respective directions.

• d_x, d_y, and d_z are the distances between the base points of the elements in the respective directions.

• n_x, n_y, and n_z are the numbers of elements in the respective directions.

• If use_link is True the created elements are App Links instead of regular copies.

• arrayis 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()
