Description
The Draft Downgrade tool downgrades the selected objects in different ways.
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
Usage
- Select one or more objects that you want to downgrade.
- Invoke the Draft Downgrade tool several ways:
- Press the
Draft Downgrade button in the Draft toolbar
- Press the D then N keyboard shortcut
- Use the Draft → Downgrade entry in the Draft menu
- Press the
- Note: If no object is selected, you will be invited to select one.
The selected objects are modified or downgraded, according to the following conditions, in order:
- If only one object is selected and it contains more than one face, each face becomes a separate object.
- If there are more than one face in the selection, the subsequent objects are subtracted from the first one. This modification is similar to
Part Cut.
- If there is only one face in the selection, it gets converted into a wire.
- Otherwise all wires found in the selection are exploded into single edges.
Options
There are no options for this tool. Either it works with the selected objects or not.
Example
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
isTrue
, 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
).
Example:
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)
