Описание

Этот инструмент разбивает выбранные объекты (преобразует объект в несколько объектов нижнего уровня). Если объекты не выбраны, попросите их выбрать.

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.

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

Использование

  1. Выберите один или несколько объектов, которые вы хотите понизить
  2. Нажмите кнопку Draft Downgrade или нажмите D, затем клавиши 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.

Опции

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

Пример

Скриптование

Инструмент Даунгрейд можно использовать в сценариях python и макросы, используя следующую функцию:

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).

Пример:

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)
