Description
The Draft PointArray tool places copies of a selected shape along various selected points.
The PointArray tool can be used on any object that was a Part TopoShape, meaning 2D shapes created with the Draft Workbench, but also 3D solids created with the Part, PartDesign, or the Arch Workbenches.
To position copies in an orthogonal array use Draft Array; to position copies along a path use Draft PathArray; to create copies or clones, and manually place them use Draft Move, Draft Rotate, and Draft Clone.
Object arranged at specific points
Usage
- Select the object that you wish to distribute.
- Select a point compound.
- Press the Draft 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 Vertices, and then press Part Compound to create the compound.
- Repeat the previous method but use Draft Upgrade to create a "Block".
- Create a Sketch, and inside add various Points.
In essence, the object to be used as the compound must have one of three properties, DataComponents, DataLinks, or DataGeometry, and inside that compound, there must be at least one point with DataX, DataY, and DataZ properties defining its position.
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
- DataBase (
Link
): the object to duplicate; it must have a Part TopoShape. - DataCount (
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 DataPoint Object. - DataExtra 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 DataBase 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 - DataPoint Object (
Link
): specifies a compound object with points that indicate where the copies of the DataBase object will appear. The compound object needs to have one of DataLinks, DataComponents, or DataGeometry properties, and contain at least one element with DataX, DataY, and DataZ 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:
PointArray = makePointArray(base, ptlst)
- Creates a
PointArray
object from thebase
object, by placing the copies alongptlst
. ptlst
is an object withGeometry
,Links
, orComponents
attributes that define the position of the copies.
Example:
import FreeCAD, Draft
Polygon = Draft.makePolygon(3, radius=500.0)
p1 = Draft.makePoint(FreeCAD.Vector(1500, 0, 0))
p2 = Draft.makePoint(FreeCAD.Vector(2500, 0, 0))
p3 = Draft.makePoint(FreeCAD.Vector(2000, 1000, 0))
# Create a compound of points
addList, deleteList = Draft.upgrade([p1, p2, p3])
# Extract the compound from the list
compound = addList[0]
PointArray = Draft.makePointArray(Polygon, compound)
