Draft Array/es

Descripción
La herramienta Matriz crea matrices ortogonalea (3 ejes) o polares a partir de los objetos seleccionados. Si no se selecciona ningún objeto, te solicitará que selecciones uno.

This tool can be used on 2D shapes created with the Draft Workbench but can also be used on many types of 3D objects such as those created with the Part Workbench or PartDesign Workbench.

To position copies along a path use Draft PathArray; to position copies at specified points use Draft PointArray; to create copies or clones, and manually place them use Draft Move, Draft Rotate, and Draft Clone.



Circular Array has been added to FreeCAD 0.19



Utilizaación

 * 1) Selecciona un objeto a partir del que desees crear una matriz
 * 2) Presiona el botón

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.

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

Properties

 * : specifies the object to duplicate in the array.
 * : specifies the type of array to create, either "ortho" or "polar".
 * : if it is, and the copies intersect with each other, they will be fused together into a single shape.

For orthogonal arrays:
 * : specifies the interval between each copy on the X axis.
 * : specifies the interval between each copy on the Y axis.
 * : specifies the interval between each copy on the Z axis.
 * : specifies the number of copies on the X axis.
 * : specifies the number of copies on the Y axis.
 * : specifies the number of copies on the Z axis.

For polar arrays:
 * : specifies the normal direction of the array circle.
 * : specifies the center point of the array circle.
 * : specifies the aperture of the circular arc to cover with copies; use 360 to cover an entire circle.
 * : specifies the number of copies to place in the circular arrangement.
 * : specifies the interval between each copy on the direction.

For circular arrays:

The number property, either X, Y, Z, or Polar, also includes the original object, so this number will be at least one.

An interval is not a simple distance, but a vector (x, y, z). If more than one value is non-zero, the copy will be created in the main direction, but will also be displaced in the other non-zero directions.

For example, if is (2 m, 1 m, 1 m), and  is 3, it will create 3 copies in the X direction; the first copy will be at the original position, the second will be displaced 2 m on X, 1 m on Y, and 1 m on Z; the third copy will be displaced 4 m on X, 2 m on Y, and 2 m on Z. Each array element will be moved slightly to one side (Y direction) and up (Z direction) beside the main X direction.

The property works in the same way. If the original shape lies on the XY plane, creating a polar array with (0, 0, z) allows you to make spiral arrangements.

Scripting
Draft API and FreeCAD Scripting Basics.

The Array tool can be used in macros and from the Python console by using two different functions, depending on if you wish to obtain standalone copies of your base object, or a parametric array object that stays linked to the original object.

Opciones

 * La matriz se inicia como ortogonal por defecto, puedes cambiar su modo en las propiedades.

To create a rectangular array, use it like this:

Propiedades

 * : Especifica el tipo de matriz orto o polar

Ejemplo:

This function internally uses and  with.

Example:

Para matrices polares:


 * : La dirección normal a la circunferencia de la matriz
 * : El punto centro de la matriz
 * : El ángulo a cubrir con las copias
 * : El número de copias

The basic signature is as follows:

Para matrices ortogonales:

Archivos de guión
La herramienta Matriz se puede utilizar en macros y desde la consola de Python utilizando la siguiente función:

Para matrices ortogonales:

Para matrices polares:
