Descriere

Acest instrument downgradează/ retrogradează/ descompune/ explodează obiectele selectate în moduri diferite. Dacă nu este selectat niciun obiect, veți putea selecta unul.

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

Cum se folosește

Selectați unul sau mi multe obiecte pe caer vreți să le downgradați
apăsați pe butonul Draft Downgrade sau apăsați pe tasta D și apoi pe N

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.

Opţiuni

Les objets sélectionnés sont modifiés / rétrogradés, dans les conditions suivantes (dans l’ordre):

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
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

Exemplu

Complete shape
Downgraded shape, with disconnected and split faces

Script

Instrumentul Downgrade poate fi folosit în scripturile python și macros utilizând următoarea funcție:

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

Downgradează obiectul/e dat/e (poate fi un obiect sau o listă de obiecte).
Dacă ștergerea este True, obiectele vechi sunt șterse.
Atributul de forță poate fi folosit pentru a forța un anumit mod de dezasambalre. Acesta poate fi: explode, shapify, subtr, splitFaces, cut2, getWire, splitWires.
Returnează un dicționar care conține două liste, o listă de obiecte noi și o listă de obiecte care trebuie șterse

Exempluː

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)
