Описание
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 App Link copies at specified points use PointLinkArray.
- 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, ДанныеComponents, ДанныеLinks, or ДанныеGeometry, and inside that compound, there must be at least one point with ДанныеX, ДанныеY, and ДанныеZ properties.
Note: in the case of Draft Point and Part Point the array will try to position the copies using the ДанныеPlacement 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 ДанныеPlacement always follows the values of ДанныеX, ДанныеY, ДанныеZ, so modifying these values is enough to produce the desired displacement. However, for Part Point, the net displacement is given by the sum of ДанныеPlacement with the vector with components ДанныеX, ДанныеY, and ДанныеZ.
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
- ДанныеBase (
Link
): the object to duplicate; it must have a Part TopoShape. - ДанныеCount (
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 ДанныеPoint Object. - ДанныеExtra 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 ДанныеBase 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 - ДанныеPoint Object (
Link
): specifies a compound object with points that indicate where the copies of the ДанныеBase object will appear. The compound object needs to have one of ДанныеLinks, ДанныеComponents, or ДанныеGeometry properties, and contain at least one element with ДанныеX, ДанныеY, and ДанныеZ 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 thebase_object
, by placing the copies in the points contained withinpoint_object
.point_object
should have one ofGeometry
,Links
, orComponents
attributes containing points.- Instead of a reference to an object,
base_object
andpoint_object
can also beLabels
(strings) of objects existing in the current document. extra
can be a fullApp.Placement
, or just anApp.Vector
orApp.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()
