Description

The Draft Upgrade tool upgrades the selected objects in different ways.

The Upgrade tool performs things such as creating faces and fusing different elements. This tool works with 2D Draft elements. To fuse 3D solids use Part Fuse and related Boolean operations of the Part Workbench, and PartDesign Boolean of the PartDesign Workbench.

The counterpart to this tool is the Draft Downgrade operation.

Open wire upgraded to a closed wire, then to a face; a closed square upgraded to a face, and then fused with the previous face

Usage

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

Example

It is worth trying to upgrade a selection several times to see if a better result can be obtained. For example:

  1. Upgrading two Draft Lines connected at one end will result in a non-editable wire.
  2. Upgrading this element again will add a third line and close the non-editable wire.
  3. Upgrading this element again will add a face to the closed, non-editable wire.
  4. Upgrading this element again will turn it into a fully editable Draft Wire.

Scripting

See also: Autogenerated API documentation and FreeCAD Scripting Basics.

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

upgrade_list = upgrade(objects, delete=False, force=None)
  • objects contains the objects to be upgraded. 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 upgrading by calling a specific internal function. It can be: "makeCompound", "closeGroupWires", "makeSolid", "closeWire", "turnToParts", "makeFusion", "makeShell", "makeFaces", "draftify", "joinFaces", "makeSketchFace", "makeWires" or "turnToLine".
  • upgrade_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=False)

line1 = Draft.make_line(App.Vector(2000, 0, 0), App.Vector(2500, 1500, 0))
line2 = Draft.make_line(App.Vector(2500, 1500, 0), App.Vector(3000, -1000, 0))
doc.recompute()

add_list2, delete_list2 = Draft.upgrade([line1, line2], delete=False)

simple_wire = add_list2[0]
add_list3, delete_list3 = Draft.upgrade(simple_wire, delete=False)

closed_wire = add_list3[0]
add_list4, delete_list4 = Draft.upgrade(closed_wire, delete=False)

face = add_list4[0]
add_list5, delete_list5 = Draft.upgrade(face, delete=False)

doc.recompute()
