Tanım

The Draft PointArray tool places copies of a selected shape along various selected points.

The PointArray 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.

To create orthogonal, polar or circular arrays, use the corresponding OrthoArray, PolarArray, or CircularArray tools.
To position copies along a path use PathArray or PathLinkArray.
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.

Object arranged at specific points

Usage

Select the object that you wish to distribute.
Select a point compound.
Press the PointArray button.

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.

Point compound

The point compound object can be created in different ways.

Create various Draft Points or Part Points, and then press Part Compound to create the compound.
Repeat the previous method but instead of a compound use Draft Upgrade to create a "Block".
Create a Sketch, and inside add various Sketcher Points.

In essence, the object to be used as the compound must have one of three properties, VeriComponents, VeriLinks, or VeriGeometry, and inside that compound, there must be at least one point with VeriX, VeriY, and VeriZ properties.

Note: in the case of Draft Point and Part Point the array will try to position the copies using the VeriPlacement of the point. In the case of a Sketcher Point, the position will be taken from its internal X, Y, and Z attributes.

Note 2: for Draft Point its VeriPlacement always follows the values of VeriX, VeriY, VeriZ, so modifying these values is enough to produce the desired displacement. However, for Part Point, the net displacement is given by the sum of VeriPlacement with the vector with components VeriX, VeriY, and VeriZ.

Options

There are no options for this tool. Either it works with the selected objects or not.

Properties

A PointArray is derived from a Part Feature (Part::Feature class), therefore it shares all the latter's properties. In addition to the properties described in Part Feature, the PointArray has the following properties in the property editor.

Objects

VeriBase (Link): the object to duplicate; it must have a Part TopoShape.
VeriCount (Integer): (read-only) specifies the number of copies in the array. This property is read-only because the number of copies is determined by the number of points inside of VeriPoint Object.
VeriExtra Placement (Placement): specifies an additional placement, translation and rotation, that will be applied to each copy in the array. Each copy normally appears with the same rotation as the VeriBase object; with this property it is possible to provide additional rotation, or counter the original rotation, and make small adjustments to the position of the copies. introduced in version 0.19
VeriPoint Object (Link): specifies a compound object with points that indicate where the copies of the VeriBase object will appear. The compound object needs to have one of VeriLinks, VeriComponents, or VeriGeometry properties, and contain at least one element with VeriX, VeriY, and VeriZ attributes.

Scripting

See also: Draft API and FreeCAD Scripting Basics.

The PointArray tool can be used in macros and from the Python console by using the following function:

Older call

point_array = makePointArray(base_object, point_object)

New call

point_array = make_point_array(base_object, point_object, extra=None):

Creates a "PointArray" object from the base_object, by placing the copies in the points contained within point_object.
- point_object should have one of Geometry, Links, or Components attributes containing points.
- Instead of a reference to an object, base_object and point_object can also be Labels (strings) of objects existing in the current document.
- extra can be a full App.Placement, or just an App.Vector or App.Rotation.

Example:

import FreeCAD as App
import Draft

doc = App.newDocument()

polygon = Draft.make_polygon(3, radius=500.0)

p1 = Draft.make_point(App.Vector(1500, 0, 0))
p2 = Draft.make_point(App.Vector(2500, 0, 0))
p3 = Draft.make_point(App.Vector(2000, 1000, 0))

compound = doc.addObject("Part::Compound", "Compound")
compound.Links = [p1, p2, p3]

point_array = Draft.make_point_array(polygon, compound)
doc.recompute()
