Descripción

Esta herramienta degrada (convirtiendo entidades complejas en otras más simples) los objetos seleccionado de diversos modos. Si no se ha seleccionado ningún objeto, te invitará a seleccionar uno.

The Downgrade tool performs things such as breaking faces, and deconstructing wires into their individual edges. It can cut a shape with another shape in similar way to Part Cut.

The counterpart to this tool is the Draft Upgrade operation.

Draft Downgrade example.jpg

Face cut from another face; then face downgraded into a closed wire; then downgraded into individual lines


Utilización

  1. Selecciona uno o más objetos que desees degradar
  2. Presiona el botón Draft Downgrade.png Degradar o presiona las teclas D y N

The selected objects are modified or downgraded, according to the following conditions, in order:

  1. If only one object is selected and it contains more than one face, each face becomes a separate object.
  2. If there are more than one face in the selection, the subsequent objects are subtracted from the first one.
  3. If there is only one face in the selection, it gets converted into a wire.
  4. Otherwise all wires found in the selection are exploded into single edges.

Opciones

Los objetos seleccionados son modificados/degradados, de acuerdo con las siguientes condiciones lista (en orden):

  • Si sólo está seleccionado un objeto y contiene más de una cara, cada cara se convierte en un objeto independiente
  • Si hay más de una cara en la selección, las caras resultantes se eliminan de la primera
  • si sólo hay una cara, se convierte en un contorno (wire)
  • en otro caso todos los contornos se descomponen en segmentos individuales

Ejemplo

Scripting

See also: Draft API and FreeCAD Scripting Basics.

The Downgrade tool can be used in macros and from the Python console by using the following function:

downgrade_list = downgrade(objects, delete=False, force=None)
addList, deleteList = downgrade(objects, delete=False, force=None)
  • Downgrades the given objects, which can be a single object or a list of objects.
  • If delete is True, old objects are deleted.
  • If force is given, it is the internal function to call to force a certain way of downgrading. It can be: "explode", "shapify", "subtr", "splitFaces", "cut2", "getWire", or "splitWires".
  • upgrade_list is returned, which is a list containing two lists: a list of new objects (addList) and a list of objects to be deleted (deleteList).

Ejemplo:

import FreeCAD, Draft

# Create an union
Circle = Draft.makeCircle(1000)
Rectangle = Draft.makeRectangle(2000, 800)

addList1, deleteList1 = Draft.upgrade([Circle, Rectangle], delete=True)
union = addList1[0]

# Downgrade the union twice
addList2, deleteList2 = Draft.downgrade(union, delete=False)
wire = addList2[0]

list_edges, deleteList3 = Draft.downgrade(wire, delete=False)

# Insert a solid box
Box = FreeCAD.ActiveDocument.addObject("Part::Box", "Box")
Box.Length = 2300
Box.Width = 800
Box.Height = 1000

list_faces, deleteList4 = Draft.downgrade(Box, delete=True)
