Draft

Beskrivning

Two overlapping faces are downgraded to a Part Cut object, which is downgraded to a face. That face is then downgraded to a closed wire, which is finally downgraded to separate edges.

1. Optionally select one or more objects.
2. There are several ways to invoke the command:
   • Press the Downgrade button.
   • Draft: Select the Modification → Downgrade option from the menu.
   • BIM: Select the Modify → Downgrade option from the menu.
   • Use the keyboard shortcut: D then N.
3. If you have not yet selected an object: select an object in the 3D View.

Scripting

To downgrade objects use the downgrade method of the Draft module.

downgrade_list = downgrade(objects, delete=False, force=None)

• objects contains the objects to be downgraded. It is either a single object or a list of objects.
• If delete is True the source objects are deleted.
• force forces a certain way of downgrading by calling a specific internal function. It can be: "explode", "shapify", "subtr", "splitFaces", "cut2", "getWire", "splitWires" or "splitCompounds".
• downgrade_list is returned. It is a list containing two lists: a list of new objects and a list of objects to be deleted. If delete is True the second list is empty.

Example:

import FreeCAD as App
import Draft

doc = App.newDocument()

circle = Draft.make_circle(1000)
rectangle = Draft.make_rectangle(2000, 800)
doc.recompute()

add_list1, delete_list1 = Draft.upgrade([circle, rectangle], delete=True)

compound = add_list1[0]
add_list2, delete_list2 = Draft.downgrade(compound, delete=False)
face = add_list2[0]
add_list3, delete_list3 = Draft.downgrade(face, delete=False)

box = doc.addObject("Part::Box", "Box")
box.Length = 2300
box.Width = 800
box.Height = 1000

add_list4, delete_list4 = Draft.downgrade(box, delete=True)

doc.recompute()
