Lo strumento Matrice crea una schiera (array) ortogonale (3 assi) o polare utilizzando gli oggetti selezionati. Se non è selezionato nessun oggetto, lo strumento chiede di selezionarne uno.

Utilizzo

  1. Selezionare gli oggetti con si desidera creare una schiera, che si desidera duplicare secondo un certo ordine
  2. Premere il pulsante Template:KEY/it

Opzioni

  • La matrice ha come impostazione iniziale predefinita quella ortogonale, è possibile modificare questa modalità nelle sue proprietà.

Proprietà

  • DatiArray Type: Specifica il tipo di matrice: ortho o polar

For orthogonal arrays:

  • DatiInterval X: The interval between each copy on the first axis
  • DatiInterval Y: The interval between each copy on the second axis
  • DatiInterval Z: The interval between each copy on the third axis
  • DatiNumber X: The number of copies on the first axis
  • DatiNumber Y: The number of copies on the second axis
  • DatiNumber Z: The number of copies on the third axis

For polar arrays:

  • DatiAxis: The normal direction of the array circle
  • DatiCenter: The center point of the array
  • DatiAngle: The angle to cover with copies
  • DatiNumber Polar: The number of copies

Scripting

The Array tool can by used in macros and from the python console by using one of the following functions.

For rectangular array:

 array (objectslist,xvector,yvector,xnum,ynum,[zvector,znum])

For polar array:

 array (objectslist,center,totalangle,totalnum)
  • Creates an array of the objects contained in list (that can be an object or a list of objects) with, in case of rectangular array, xnum of iterations in the x direction at xvector distance between iterations, and same for y direction with yvector and ynum. In case of polar array, center is a vector, totalangle is the angle to cover (in degrees) and totalnum is the number of objects, including the original.
  • This function produces standalone copies of the base object(s)

Or

For rectangular array:

 makeArray (object,xvector,yvector,xnum,ynum)

For polar array:

 makeArray (object,center,totalangle,totalnum)
  • Creates an array of the given object with, in case of rectangular array, xnum of iterations in the x direction at xvector distance between iterations, and same for y direction with yvector and ynum. In case of polar array, center is a vector, totalangle is the angle to cover (in degrees) and totalnum is the number of objects, including the original.
  • The result of this function is a parametric Draft Array object.

Example:

 import FreeCAD,Draft
 Draft.array(FreeCAD.ActiveDocument.ActiveObject,FreeCAD.Vector(2,0,0),FreeCAD.Vector(0,2,0),2,2)
