Descripción
La herramienta PathArray coloca copias de una forma seleccionada a lo largo de una ruta seleccionada. La ruta puede ser un alambre o uno o más bordes. Las formas pueden alinearse opcionalmente con la tangente del camino. Si es necesario, se puede especificar un vector de translación para cambiar las formas de modo que el centroide esté en la ruta. Si no se seleccionan objetos, se le invitará a seleccionarlos.
Both commands 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 Arch Workbench.
Draft PathArray
Como utilizar
- Crea un objeto de forma que desees distribuir. Obtendrá los mejores resultados si su objeto está centrado en el origen, incluso si la ruta comienza en otro lugar.
- Seleccione un objeto de ruta a lo largo del cual se distribuirán las formas. -o-
- Seleccione algunos bordes de un objeto de ruta.
- Presiona el botón Draft PathArray .
Alignment
The alignment of the elements in a Draft PathArray depends on the properties of the array and the orientation of the source object. The position of the source object is ignored: for the purpose of the array the x
, y
and z
are set to 0
. If the DatosAlign property of the array is set to false
the orientation of the array elements is identical to that of the source object. If it is set to true
the X axis of the local coordinate system of each element placement is tangent to the path. The Y and Z axes of the local coordinate systems depend on the DatosAlign Mode property of the array. Other array properties involved in the alignment include DatosTangent Vector, DatosForce Vertical and DatosVertical Vector.
3 arrays based on the same non-planar path. From left to right: Align is false, Align is true with Align Mode Original and Align is true with Align Mode Frenet
.
Align Mode
Three modes are available:
Original
This mode comes closest to the single DatosAlign Mode available in version 0.18. It relies on a fixed normal vector. If the path is planar this vector is perpendicular to the plane of the path, else a default vector, the positive Z axis, is used. From this normal vector and the local tangent vector (the local X axis) a cross product is calculated. This new vector is used as the local Z axis. The orientation of the local Y axis is determined from the local X and Z axes.
Frenet
This mode uses the local normal vector derived from the path at each element placement. If this vector cannot be determined (for example in the case of a straight segment) a default vector, again the positive Z axis, is used instead. With this vector and the local tangent vector the local coordinate system is determined using the same procedure as in the previous paragraph.
Tangent
This mode is similar to DatosAlign Mode Original
but includes the possibility to pre-rotate the source object by specifying a DatosTangent Vector.
Force Vertical and Vertical Vector
These properties are only available if DatosAlign Mode is Original
or Tangent
. If DatosForce Vertical is set to true
the local coordinate system is calculated in a different manner. The DatosVertical Vector is used as a fixed normal vector. From this normal vector and the local tangent vector (the local X axis) again a cross product is calculated. But now this vector is used as the local Y axis. The orientation of the local Z axis is determined from the local X and Y axes.
Using these properties can be required if one of the edged of the path is (almost) parallel to the default normal of the path.

Scripting
Programación
La herramienta PathArray puede usarse en macros y desde la consola de Python utilizando la siguiente función:
path_array = make_path_array(base_object, path_object,
count=4, extra=App.Vector(0, 0, 0), subelements=None,
align=False, align_mode="Original", tan_vector=App.Vector(1, 0, 0),
force_vertical=False, vertical_vector=App.Vector(0, 0, 1),
use_link=True)
- Distribuir recuento de copias de un objeto de forma de documento a lo largo de un objeto de ruta o subobjetos de un objeto de ruta. Opcionalmente, traduce cada copia por FreeCAD.Vector xlate la dirección y la distancia para ajustar la diferencia entre el centro de la forma y el punto de referencia de la forma. Opcionalmente alinea el objeto base con la tangente / normal / binormal de la ruta.
Ejemplo:
import FreeCAD as App
import Draft
doc = App.newDocument()
p1 = App.Vector(500, -1000, 0)
p2 = App.Vector(1500, 1000, 0)
p3 = App.Vector(3000, 500, 0)
p4 = App.Vector(4500, 100, 0)
spline = Draft.make_bspline([p1, p2, p3, p4])
obj = Draft.make_polygon(3, 500)
path_array = Draft.make_path_array(obj, spline, 6)
doc.recompute()
wire = Draft.make_wire([p1, -p2, -p3, -p4])
path_array2 = Draft.make_path_array(obj, wire, count=3, extra=App.Vector(0, -500, 0), subelements=["Edge2", "Edge3"], align=True, force_vertical=True)
doc.recompute()
